Over the years, our clients have asked many questions about their electrical systems; how to best care for them, what the cause of certain issues are, and more. We’ve compiled just a few of the most common questions we get below, with our responses.

A: Is the switch all the way in the “off” position? You have to feel it click off before you can reset it. If you are able to return it to the “on” position—you’ll feel another click—and it does not trip again, then you were successful. If it continues to trip, then there could be a chance that you have a short circuit or an overloaded circuit. Quite often, an electrical panel upgrade is the solution.

A: There are a number of possible reasons this can be occurring. First, check for a tripped circuit breaker. Then, if it’s a GFCI outlet, check for a reset button right on the outlet itself. Push that, if there is one. In the absence of either of these issues, then it may just be an old outlet that needs replacing. Just like any other electrical component, it can wear out over time and is usually no reason for huge concern.

Do, though, make sure you don’t smell or see any smoke or smoldering—this can be indicative of frayed wires starting an electrical fire. If you do detect smoke, your next step is to call the fire department.

Flickering can happen with certain types of lightbulbs and are sometimes not a cause for concern at all. However, if either of flickering or dimmer are occurring when you turn something on or an appliance cycles on in your home, then you probably have an overloaded electrical panel. Another possibility is that the lightbulbs you have installed in whatever fixture is creating the issues are not adequate bulbs for that fixture.

When you are using an electronic device and need to charge it, you look for the closest power point to plug it in. There are times when you just can”t find a plug point within easy reach; that’s when you look for an electrical extension cord and plug in the device you need to charge.

This is something most of us do as a matter of routine and we don’t give much thought to it. Extension cords are undoubtedly a very handy tool that solves some very basic charging problems. When there is a shortage of outlets or if an electronic device is just a little too far from the closest electrical point, these extension cords prove very useful.

However, it’s important to keep in view the fact that an extension cord isn’t meant to be a permanent electrical fixture; it’s to be used for a specific reason and it can be hazardous to use them incorrectly.

Here, we talk about the different hazards of electrical extension cords and how they can be avoided:
