Dedicated Electrical Circuits and Required Appliances, Part 2

In part one of this two-part blog, we went over some basics on dedicated electrical circuits and the kinds of appliances or equipment that tend to require them. Commonly used for high-powered or larger appliances, dedicated circuits power a single appliance or application within a structure, never diverting power to any other source.

At My Buddy the Electrician, we’re proud to offer a range of residential and commercial electrical services, including expertise on dedicated circuits and all other related areas you might have concerns in. For many home or building owners, you might be unsure whether a given appliance is on a dedicated circuit in your structure – today’s part two of our series will go over how you can make this determination and identify the dedicated circuits being used for certain appliances.

What Trips Breakers?

We went over some basics on circuits in part one, and as many home and building owners are well aware, these connect to a central circuit box, or group of circuit breakers. In cases where your structure’s electrical capacity is dwindling or being overused, certain breakers assigned to various appliances may trip, or shut off power to their assignments.

One simple way to determine which of your appliances is on a dedicated circuit, if you’re unaware, is to test their tripping points. Have you noticed that certain appliance combinations, for instance, trip the breaker and cause an outage? This is a clear sign that none of the appliances involved in this combination are on a dedicated circuit – and if this problem persists with certain appliances, you should strongly consider a dedicated circuit for them to stop these issues from taking place.

Electrical Box Labels

Now, there are many cases where you will not have to perform any of those tests because the electrician who wired your home did the work for you. The best electricians will label all the circuits in the breaker box, including dedicated circuits only meant for a single appliance.

Outlet Tests

Now, sadly, this isn’t the case for all electricians. There are plenty of cases where circuit boxes are not properly labeled, or not labeled at all.

An alternative test method here for dedicated circuits is testing the outlets themselves using an approved testing product. Such products include neon testers, voltmeters and tick-tracers, all of which can be plugged into a given outlet and will light up if the circuit is hot (or stay unlit if it’s dead). Before doing this, turn off all the labels in your electrical box except one, then test the outlet or group of outlets you think is being powered using your test device. This allows you to not only match up your devices or areas with your breaker box labels, but also to identify dedicated circuits for certain high-power appliances.
