5 Little Known Facts About Electric Vehicle Charging Station Installations

A 2020 report published by the International Energy Association estimates that there will be 245 million electric vehicles on the roads by 2030. This means that there has to be a robust electric charging station infrastructure installed and in place by that time. This creates a need for widespread electric vehicle charging station installations in homes, offices, and other businesses. Here are a few little-known facts about electric vehicle charging stations:

1 – Experts Expect the Percentage of Electric Vehicles within the Overall Vehicle Stock to be 30% by 2030

The EV30@30 initiative aims for the global passenger electric vehicle stock to consist of at least 30% EVs by 2030. This target assumes an annual growth rate of about 36% between 2019 and 2030.

2 – Interest in Electric Vehicles Has Been Increasing Steadily

As of 2020, nearly 1.8 million EVs were registered in the U.S., more than three times as many as in 2016, according to the International Energy Agency (IEA). In a recent Pew Research Center survey, 7% of U.S. adults already have an electric or hybrid vehicle, and 39% stated they are very or somewhat likely to seriously consider buying an electric vehicle the next time they’re in the market for a new vehicle.

3 – Electrical Vehicle Charging Station Installations Also Rising Steadily

According to the evadoption.com website, the number of DC fast chargers grew by more than 4,200 ports, a 24 percent increase at the end of 2021 versus year-end 2020. EV charging infrastructure construction initiatives have been earmarked with $7.5 billion, combined with the Department of Energy’s low-interest loan program, an expected doubling of new EV sales in the US, and nationwide companies such as Circle K and 7-Eleven getting into providing EV charging infrastructure, ensures more significant growth in 2022.

4 – New Homes Required to Provide EV Charging Stations

In the UK, EV charging stations installed in new homes have been a standard practice for several years.  In 2020 the International Code Council (ICC) approved US building code changes to ensure that all new homes are “EV ready” by mandating EV charging station installation. Soon the electrical infrastructure for EVs will be as common as installing a 240-volt outlet for home appliances.

5 – Off-Grid Solar Charging Stations Technology Emerging

A combination of highly efficient solar panels and solar storage solutions makes an electric vehicle charging station feasible. This is especially helpful for those who don’t travel far or often in their electric vehicles.

Radial vs. Ring Power Distribution Systems – What Are the Differences?

Most commercial and industrial electrical system installations involve an electrical power distribution system. An electric power distribution system is between the transmission station and individual industrial and commercial customers. Typically, this power is transmitted at a lower voltage than the transmission of power over long transmission lines over great distances. The distribution system tends to step down power to commercial and industrial electrical systems.

The most common electrical power distribution systems include:

  • Radial Power Distribution Systems
  • Ring Power Distribution Systems

What is a Radial Power Distribution System?

A radial power distribution system is used for substations or generating stations located at the center of the customer’s location. For a radial PDS In this system, the feeders push electricity from one end to the distributors located at the other end. The energy can only flow in one direction.

Advantages of Radial PDS

  • Simple design and setup
  • Low initial cost

Disadvantages of Radial PDS

  • Not as reliable as other systems
  • A fault in one feeder cuts off power to the distributor and doesn’t provide any backup feeder

Radial Parallel Feeder Distribution Systems

There is a version of the radial power distribution system called a parallel feeder power distribution system. This doubles the number of feeders within the system, which improves reliability but adds considerable expense due to the doubling of the feeders.

What is a Ring Power Distribution System?

Ring distribution systems are designed so that every distribution transformer connects with two feeders using different paths. These feeders form a loop that starts at the substation bus bars, goes through the load area feeding distribution transformers and returns to the substation bus bars.

Advantages of a Ring PDS

  • Very reliable system
  • Fewer voltage fluctuations at terminal locations
  • Improved continuity of the power supply

Disadvantages of a Ring Main Distribution System

  • High initial cost.

CCTV installation by Tri-State Electrical a premier CCTV installation company in Chattanooga

7 Beneficial Uses of CCTV

CCTV is the abbreviation for Closed-Circuit Television. The difference between CCTV and standard TV is that in CCTV, the video only broadcasts to a limited network of monitors, not over the airwaves. CCTV has been around for decades, and installing a Closed-Circuit Television network is still a cost-effective way to transmit video within your home or business. Here are just a few of the ways to use CCTV.

1 – Video Surveillance

Most uses of CCTV involve video surveillance of some sort. Most commonly to prevent or prosecute criminal activity. Using video surveillance in high-crime areas helps gather evidence for investigations, deter illegal activity, and provide eyes on more secluded sites such as stairwells, garages, rooftops, and back alleys.

2 – Workplace Surveillance

Video surveillance via CCTV helps reduce incidences of internal theft, sexual harassment, and other inappropriate activities at the workplace. The presence of cameras make employees think twice before misbehaving.

3 – Emergency Information

A CCTV camera can be moved into dangerous emergencies such as a hostage situation, a fire, or weather-related calamity and the first responders can safely review and monitor these situations without putting them in danger.

4 – Monitoring Traffic

Not only can CCTV be used at traffic lights to catch drivers speeding or running red lights, but they can also monitor traffic and other events and conditions in real-time or monitor community street activities. This information can also be used for research purposes to improve traffic flow and provide up-to-the-minute information about the traffic within the city.


5 – Child Safety

A video baby monitor is a simple CCTV system. This allows you to monitor the kids to ensure they are safe and alert you if they are awake or in distress.

6 – Improving Safety at Your Business

Having CCTV cameras active in the parking lots, hallways, stairwells, and other public spaces of your business creates a sense of security among your employees and customers. CCTV can also deter potential thieves by making them look for easier targets with less surveillance.

7 – Marketing Research

CCTV can provide valuable data about shoppers who visit brick-and-mortar stores such as:

  • How customers move around the store
  • Which areas of the store attract the most traffic
  • Which aisles get the most traffic within the store
  • When are the busiest times for the store

These are just a few of the ways that CCTV can be used to improve your home, workplace, or business.

What is Involved in an Electric Vehicle Charging Station Installation?

If you have recently purchased a hybrid or electric vehicle (EV) or own or manage a business, there will be a time very soon when you will need to install a charging station. There are several steps involved with installing an EV charging station.

Electric vehicle charging station installation in Nashville

Location Assessment

One of the most important parts of installing an electric vehicle charging station is finding the right location for it. For a home charging station, this is easy. Install it where you park the vehicle. For a business, this can be complicated because you have to consider several other factors:

  • How many employees or customers have an EV
  • A location where to construct the EV charging station
  • How many vehicles can be charged at one time
  • Does the location have an adequate power infrastructure in place to support the EV charging station(s) to be installed? Or does the power infrastructure require an upgrade to handle the workload?
  • Is the location well-lit and secure?

Infrastructure Assessment

A reputable team of EV charging station installers takes time to review the infrastructure that will support the charging station. In addition to reviewing the power infrastructure, the team may determine if any construction, concrete work, or excavation needs to happen within and around the charging station site.

Obtaining Permits and Inspections (if applicable)

The EV charging station team will work with local officials and agencies to line up the proper permits and inspections for the construction of the charging station.

Incentive Review

There are many city, state, and Federal incentives and rebates available for customers who install green energy infrastructure. These can be tax breaks, utility company rebates, and local and state credits. These vary from location to location. Be sure to work with an experienced electric vehicle charging station installer to help apply for all the rebates you qualify for.


This stage of the process may involve some excavation, running electrical cables to buildings, building the infrastructure surrounding the EV charging station, such as a charging bay, light poles, landscaping, and much more.

7 Benefits of Installing Optical Fiber Cabling Over Copper Wire

Copper cables have been the gold standard for most wiring jobs for over 100 years. They are highly conductive and great for voice transmission. But fiber optic cable is superior in many ways for structured network and backbone cabling. Here are some of them.

1 — Transmits Faster

Because fiber optic cables use a light core to carry and transmit data, the signals travel at about 70% of the speed of light (or close to 470,000,000 MPH). This is much faster than any copper cable can manage. As a result, there is also less signal degradation with fiber cables.

2 – Carries Signals Over Longer Distances

Copper wiring has a limitation of around 328 feet before the signal degrades. Fiber optic cables can carry signals much farther—miles instead of feet. The distance depends on the fiber optic cable type used, the signal’s wavelength, and the network that supports it.

3 – Greater Bandwidth

When comparing copper cables to optical fiber cables of a similar size, fiber optic cable carries far more data than copper cables can.

4 – More Reliable

Copper carries electricity. As a result, bad weather, extreme temperature changes, and even a little moisture can reduce copper cables’ connectivity and effectiveness. Also, because it carries electric current, it is susceptible to electromagnetic interference (EMI), which can disrupt transmission. Because fiber uses light instead of an electric current, it is immune to extreme temperatures, bad weather, EMI, and moisture. It is also corrosion-resistant.

5 – Lighter and More Rugged

Copper is heavy and bulky. When comparing fiber cables to copper cables, fiber optic cables are thinner and lighter. Because of the nature of fiber optic cable, it is far less fragile than copper. It can be pulled, bent, and twisted in ways that copper cannot.

6 – Easier to Install

When installing cabling, copper can be more challenging because it has to be thicker to handle the bandwidth of a typical organization. For this reason, it is challenging to run copper wire through walls, it requires bigger holes to run them through and more construction to make the copper cable work smoothly. Because fiber optic cable is significantly thinner, it requires a lot less space and work to get them where they need to go in a building.

7 – Integrates Well Into Existing Technology

Today’s network equipment manufacturers produce components that allow you to integrate fiber-optic-cable into existing networks. Because fiber optic cable uses light instead of electricity, it can be installed along old electrical cables without causing interference.

Two Things You Need to Know About Electric Vehicle Chargers

Since 2010, over 2.4 million hybrid and electric vehicles have been sold in the US. Between January 2021 and January 2022, there has been a 37% increase in the number of “plug-in” electric vehicles and hybrids sold. With a Biden Administration executive order targeting 50% of all vehicle sales to be electric vehicle sales by 2030, US drivers have numerous incentives to purchase these vehicles. What does this mean for you? A greater need for infrastructure to support electric cars. But what are some of the things you should know about electric vehicle chargers?

Electric vehicle charging station in Chattanooga

There Are Different “Levels” of Electric Vehicle Chargers

A Level 1 charger uses a standard 120-volt electric outlet which most homes already have in their garages or near where they park their vehicles. The convenience is great, but the speed of charging using a 120-volt is very slow, up to 8 hours to fully charge a hybrid and up to 20 for an electric vehicle. And for commuters who drive a lot, that might be a problem.

Level 2 chargers use a 240-volt outlet—like the one used by your dryer and allow you to charge your vehicles up to 5 times faster than a Level 1 charging station.

Level 1 and Level 2 charging stations are designed for residential use. Level 3 charging stations use very high voltages to charge electric vehicles quickly and are better used in commercial applications when many vehicles need one charging station.

The Cost of Electric Vehicle Chargers

There are two significant expenses associated with powering electric vehicles; the cost of hiring a qualified commercial electrical company to install an electric vehicle charging station and the cost of electricity.

The cost of charging the average electric vehicle is about the same as running the average central air conditioning system for 6 to 12 hours. When compared to the price of gas, this cost is a bargain.

Although you can install an electric vehicle charging station yourself, that might not be a good idea. If it isn’t done correctly, the charging station may damage the vehicle’s battery which is (by far) the most expensive component in the vehicle. Instead, having a trained professional such as the commercial electricians at Tri-State Electrical Contractors is a better idea. At Tri-State Electrical, our electricians have been trained to properly install electric vehicle charging stations and can do it for residential, commercial, or industrial electrical customers.

Industrial electrical contractors troubleshooting industrial electrical problems

4 Common Challenges Industrial Electrical Contractors Face

Industrial electrical contractors are highly-specialized workers in a highly specialized field. Although many of the challenges they encounter are not unique, awareness of them is critical to avoid damage, injury, and potential work stoppage due to these issues.

Industrial electrical contractors troubleshooting industrial electrical problems

1 – Power Surges

Where surge protectors protect personal computers and other electronic items in our homes, power surges are more common in industrial environments and more damaging because of the size and power needed by the equipment used in the building. Industrial electrical contractors understand this and design power systems that can handle these surges while protecting the company’s equipment and employees.

2 – Power Loss

Whether due to storm damage, accident, or planned maintenance, industrial businesses must keep running regardless of the situation. As a result, industrial electrical companies provide a variety of backup power generation sources such as backup generators or off-grid power sources such as solar and wind. In most industrial environments, downtime is never a good thing.

3 – Worn Out Equipment

Most industrial equipment gets a lot of use; as a result, wear and tear are inevitable. However, some of these problems are easy to resolve because they are designed to be replaceable, such as bulbs, fuses, and switches.

Other problems require some troubleshooting, and because of the nature of industrial equipment and environments, this may require industrial electrical troubleshooting to identify the issue. This type of troubleshooting requires extensive knowledge and experience with the company’s environment and variety of equipment. In addition, this type of troubleshooting may involve using highly-specialized equipment for issues that are particularly difficult to track down.

4 – Defective Wiring

Wiring is the most common point of failure within industrial electrical equipment and, in many ways, the most dangerous. When wiring isn’t installed correctly, is the wrong gauge for the job, or the insulation is worn away, it is unsafe and sometimes tricky to find. A knowledgeable industrial electrical contractor can help mitigate these issues and fix them when they encounter them.

Testing by one of the best structured cabling field testing companies in Knoxville

What is Structured Cabling Field Testing?

To understand structured cabling field testing, you need to understand about structured cabling is. According to the Fiber Optic Association, structured cabling is “the standardized architecture and components for communications cabling specified by the EIA/TIA TR42 committee and used as a voluntary standard by manufacturers to ensure interoperability.”

Testing by one of the best structured cabling field testing companies in Knoxville

Defining Structured Cabling

In plainer language, it is the communications cabling infrastructure for a home or business. Most modern companies and businesses require a lot of connectivity, whether these are computer networks, phone systems, or other communication systems supporting the company’s business operations. In addition, the performance of these systems must be

  • Consistent and predictable—the performance of the operation must meet the expectations of everyone, including workers, managers, and customers
  • Flexible – to make changes, additions, removals, and transferal of connectivity
  • Redundant – so problems in one area won’t bring operations to a screeching halt

Structured Cabling Field Testing

The Telecommunications Industry Association (TIA) develops and publishes the voice and data communications infrastructure standards. These standards include performance specifications for twisted-pair cable, connecting hardware, and how well this equipment is installed within the location. The TIA telecommunications systems bulletin TSB-67, defines the guidelines for field testing the two models for the installed link: channel and basic link. It also defines

  • The parameters that need to be measured and verified
  • The frequency range over which the evaluation needs to be executed
  • The performance or pass/fail limits for this evaluation.
  • The framework for performance analysis

Field-testing a structured cabling system ensures that a completed installation meets the desired transmission performance outlined by TSB-67. The test verifies that the installed link transmits signals with a high degree of integrity to ensure reliable communications. By reviewing the signal-to-noise ratio (SNR) of the transmission link over the frequency range required by the application, the tester determines the strength of the signal to be received from the sender–relative to external disturbances such as noise on the transmission link. If your signal is strong compared to the effect of unwanted disturbances, the signal has a low bit-error-rate.

Running a series of structured cabling field tests helps identify issues within the hardware, configuration, and the installation of the structured cabling and supporting hardware. This is an essential component of keeping your communication network running smoothly and identifying potential issues before they can slow down (or even stop) production.
