"A great experience. Met with owner, Mohammed within 1 hour of contact. He looked at job, explain the issues in plain English. Gave me several options to resolve electrical problem. Promised to follow-up with phone call after he got pricing on parts. Called me bright and early very next morning, we agreed on work to be done and pricing, he said he could complete today. Within 1 hour he started repairs and within a few hours, the A/C and entire home was up and running. He checked/confirmed that every electrical appliance had power. His work area was left clean and free of trash. It was a pleasure to have Mohammed in my home, a true professional"

Electrical FAQs, answered by experts

Yes, if something sparks when you plug it in or turn it on, it's important to unplug it immediately. A spark from an electrical appliance or device could indicate a short circuit, damaged wiring, or other electrical problems that could cause electrical fires or electrical shock. By unplugging the appliance, you can reduce the risk of electrical hazards and prevent damage to the device itself. It's important to avoid using the appliance until it has been inspected and repaired by a licensed professional to ensure that it’s safe to use.

That depends on your setup. If a circuit breaker already has GFCI protection, then everything connected to that specific circuit is being monitored. You don’t need additional GFCI outlets on that breaker.

However, if the breaker is not GFCI, then you should have GFCI receptacles for at-risk outlets nearby water sources, because they are not receiving protection. Breakers in a breaker box can vary between GFCI and non-GFCI. Look for GFCI labels on the breaker or try to find the breaker model number to look it up if you aren’t sure.

Check the matching breaker in your panel, since the number is printed on the switch. You can also tell them apart by sight. A 15-amp outlet has two straight vertical slots, while a 20-amp outlet has one vertical slot and one sideways T-slot.

The National Electric Code states that outlets should not be spaced more than 12 feet apart, and there should be an outlet placed every 6 feet at the floor line in areas designated as living spaces. Most homes in the United States have 75 outlets, but it will depend on the amount you need based on your home's size and your needs.

You can test an electric fence with a multimeter, but you’ll need to set the multimeter to the correct voltage measurement—such as alternative current (AC) or direct current (DC) and range—depending on your fence. You can find the voltage type and range in the fence’s user manual.
