"Antonio, was very friendly, he replaced the outside light and the kitchen light. The kitchen fan had a down pole. I wasn’t satisfied with the movement. He took the fan down numerous times to make sure I was satisfied. He did a great job and I will use his services again."

Electrical questions, answered by experts

You can use a double-pole switch for a regular light fixture, but it's unnecessary and won’t be the most efficient choice. A single-pole switch works perfectly for standard lights. Double-pole handle high-power appliances that require both hot wires to be disconnected. Using a single-pole switch for regular lights is more cost-effective, simpler, and more common in residential settings.

It's less expensive to run power overhead because it doesn’t require excavation, and the power cables are less costly. However, underground electric service is better protected from weather and general wear and tear, so it’s less likely to get damaged. When determining which way to run power, consult a local electrician to get an expect opinion.

Knowing if and when your circuit breaker is failing or faulty can prevent costly damage. If you notice any of the following signs, call a local electrician to help. 

  • The breaker frequently trips

  • The breaker doesn't stay in the 'on' position or reset properly

  • You hear buzzing or humming noises coming from the breaker

  • There's discoloration around the breaker switch

  • There's a burning smell or visible signs of damage on the breaker

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.

You should never plug a normal 120v appliance into a special 240v outlet, as it can quickly burn out the appliance. This will cause irreparable damage to the appliance and, in worse case scenarios, cause damage to your circuit breaker. Check your appliance’s rating before plugging it into a 220v outlet to avoid electrical disaster.
