"I had a car charger installed and was really happy with the work. He was responsive, showed up when he said he would, and the install came out clean and professional. Everything was explained clearly, the work area was left neat, and the charger works exactly as it should. Definitely someone I?d recommend if you need electrical work done."

"The problem turned out to be a burned out small electric door switch. I believe the price was way too expensive for the service performed and the price of the door switch. What more can I say? It got done."

Electrical questions, answered by experts

Light switches can last for decades when installed and maintained correctly. Improper wiring, heavy wear and tear, or too much wattage draw can cause light switch failure long before the expected end of a light switch’s life. Light switches that are hot to the touch, making a buzzing noise, or failing to work consistently should be inspected to find and repair the underlying cause.

The common, marked as COM or C, is one of the terminals found in your light switch. It houses the live wire that supplies the input voltage. The other terminals, marked as L1 or L2, are the outputs to the light fixtures. Depending on if you have a one-way or two-way switch, you’ll either have just an L1 terminal or both an L1 and L2 terminal.

Local building codes typically require conduit around exterior wiring. Conduit protects the wire from moisture, extreme temperatures, sun exposure, and harsh weather conditions to prolong its lifespan. When a wire is worn out, it can be dangerous as the risk of electric shock or fire increases.

A light switch should be at least 2 inches from the edge of the trim of a door. The location of wall studs will often help determine where to put the light switch by your doorway, and in most cases, wall studs make it impossible to install the switch closer than 2 inches. When possible, try to keep the switch within arm’s length of the entryway.

Be careful not to drop your voltmeter or multimeter. Even a small fall can affect the tool’s ability to measure with accuracy. Always store your tools in their cases in a cool, dark place. Also, avoid touching the probes to each other while they’re connected to a circuit or another electrical component, and never tamper with anything inside the device.
