"I have a very good impression of Mr. Morton and appreciate his efficiency and speed in getting my generator back in service. I have asked him to put me on his list for a yearly evaluation. I am trusting that the next time there is a power failure my generator will be back in operation."

Electrical questions, answered by experts

It’s possible to distinguish a positive black wire from a negative black wire if you know what type of circuit the wires are in. If it’s an alternating current (AC), then black wires are positive. If it’s a direct current (DC), then black wires are negative. 

Sometimes, a circuit has two black wires. In that case, the positive black wire will be solid black while the negative black wire will have a white stripe on it. If you’re still unsure, you can use a multimeter to check.

Thankfully, LED lights use less electricity than incandescent lights, meaning you won’t spend as much on utility bills by using these light strips. Each 5-meter LED light strip will cost about $3 per year on your energy bill.

When wiring a switch, the power typically comes into the receptacle first. The neutral wire goes straight to the outlet, while the hot wire is split. You'll need a wire nut to splice the hot wire back to one of the receptacles, but you will also tie another wire into that same wire nut and run to the switch. That way, you can control the flow of electricity to that particular receptacle by turning the switch on and off.

Unfortunately, a partial power outage without a tripped breaker often means you have a major wiring issue or that the breaker itself is going bad. When the power is out in one room but the breaker is not tripped, you need to call an electrician as soon as possible to identify the cause of the problem and repair it.

There are several reasons why an electrical outlet would suddenly stop working, including:

  • Broken parts in the outlet

  • Outlet burnout

  • Circuit breaker tripped

  • Damaged circuit breaker

  • GFCI outlet tripped

  • Damaged or loose wires

  • Failed connectors

  • Appliance failure
