The term “arc flash” is used to describe low impedance connections in an electrical system, which allows movement of unwanted electric discharge through the air from one voltage phase to another, or to ground. This leads to a rapid rise in temperature and pressure in the air between electrical conductors, causing an explosion known as an arc blast.

Arc blasts and the resulting heat can lead to fires, pressure waves and flying shrapnel that result in serious damage to life and property. These explosions typically occur without any warning, destroy electrical equipment completely and lead to severe injury or death of personnel present within the boundary of the arc flash.

What Are the Main Causes of Arc Flash?

Arc flash occurs when several electrical conductors are placed close to each other, with significant fault currents flowing through them. In this situation, ionization of the air can take place as a result of various factors – such as differences in potential – which leads to a low resistance path and allows current to flow through the air gap between conductors.

Many people assume that low voltage equipment is safe from arc flash, but arc flash hazard levels may be higher at low voltages, due to the high fault currents. Most incidents that occur in low voltage systems are caused by human error, e.g. a tool slipping while a technician works on electrical equipment.

Arc flash can also be caused due to:

Electric cars are increasing in popularity as more people realize how economical the cars are. Gas prices are constantly on the rise and people are desperate to find a way to save money. Not to mention, electric cars are great options for those who are interested in preserving fossil fuels. If you have bought an electric car already or plan on purchasing one, you are probably interested in learning about how you can charge the car.

Your electrician in Glendale explains what you need if you are planning on charging your car at home. Depending on where you live, this may be a necessity. While public charging stations are becoming more popular, it is not always convenient to drive to a station and wait. At The Electric Connection, we understand the desire many people have to install a charger in order to charge the car overnight or whenever the car is not in use.

Electric car chargers are available in two main sizes. The smaller, slower charging station can be plugged in virtually anywhere. This station will not typically require an electrician’s help. The only time you would need to call a Glendale electrician is if you do not have enough outlets near where you park the car or you need an additional breaker to support the charging station.

If you are interested in the stations that charge the car in half the time, you will definitely need an electrician’s services. A new, higher voltage outlet will need to be installed. Depending on the current breaker panel in your home, you may also need an electric panel upgrade. A dedicated breaker will need to be installed that will be solely for the car charger.

If you are interested in learning more about your electric car charging options, please give The Electric Connection a call. We would love to assist you.
