Just like any other electrical tasks, it is important for any homeowners to learn a couple of troubleshooting tips before starting with any DIY light switch wiring projects. In fact, there are many factors to examine when you plan to troubleshoot an electrical area, but the followings are 4 most basic things.
Understanding those useful tips, and you will find it much simpler to do any light switch wiring tasks.
Before getting started
As usual, you need to ask yourself a couple of questions before starting the project. First, is the power or switch off? Or, are the light bulbs burned out? In addition, it is necessary to check if the GFCI is tripped or the GFI receptacle. Lastly, is the fuse blown or the breaker tripped? If this is the case, you should identify the underlying cause.
Safety is the top priority
A safety tip to remember before the examination is that you should never work with an energized wire or circuit. Thus, it is necessary to find out and turn off the circuits. After that, mark the circuit to inform other people in the family that you are working on it and they should leave it off.
Before any wire testing, make sure to insulate the wires with a good piece of electrical tape or cap them with wire nuts. This is especially necessary if you need to turn the circuits on.
In addition, keep in mind to keep the hot wire with either red or black electrical tape. By doing this, you can differentiate it from other wires in the system.
Identify loose connections
One of the main problems that you might face while troubleshooting the light switch wiring might be loose connections. Thus, ensure that the wires are firmly attached to the switch. What’s more, double check to make sure that the screws are properly tightened to keep those wires in place.
Check the wire ends
Similarly, have a look at the wire ends for any sights of frayed, nicked or bent areas. If one of these problems happens, the connection might be negatively affected. To resolve this problem, you should cut those wire ends and remove the plastic cover until it reveals about 1 inch of raw wire.
Examine exposed bare wires
Another thing to consider might be the bare wires, which would be exposed to and touch the electrical box. As a result, it would trip the circuit breaker or blow the fuse.
To avoid this issue, make sure to coat your wires with adequate plastic sheathing. If they are not protected enough on the outer.
Replace the switch
In most cases, a complete replacement of the switch is the only solution to wiring issues in your house. This is simply because switches work as mechanical components that are able to stop and break down functioning. After using for several years, those units will quickly wear out. Thus, it is advisable to replace the old switch with a new one.
But before making this replacement, keep in mind to choose a good switch that can work well with the circuit, A common way to check a new switch is that it should have the same terminals and screws like the one.
