"Turned out that only a few plugs were bad and needed to be switched out and the rest of the plugs on the circuit begin to work . He explained what he was doing and showed me the problem and how to correct on my own if happens again. Will definitely be hiring again in the future for any electrical needs ."

"William, the Technician was very professional and discovered the problem right away. Then informed me that he would perform a safety check on all the electrical connections in the electrical panel free as part of the agreed on pricing. This was a really good experience and would highly recommend Mr Electric North West to anyone who need electrical help!"

Electrical questions, answered by experts

A sump pump can be plugged into a regular, 110-volt outlet with three-prong openings, but it must have GFCI protections per the NEC, meaning you’ll need a GFCI outlet and circuit. Sump pumps require two outlet openings, one for the plug to the motor and one for the float switch.

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.

Yes—if a breaker is old or damaged, it might not be able to detect power surges or electrical overload. If that happens, the breaker won’t trip. Instead, it will begin to overheat, putting your electrical system at risk of fire or total electrical failure. Circuit breakers don’t last forever, so you can proactively replace old or damaged breakers before they stop working.

In the United States, home outlets support a standard 15 amps, but you can upgrade per outlet if necessary. Most single-family residential homes have a maximum overall amp rating, usually 100 to 200 amps. Very old houses may have less than 100 amps, but that’s rare. Large homes often come with amp services above 200 amps to support modern lifestyles.

Outdoor outlets should be at least 15-amp, but preferably 20-amp. The exact rating will depend on the electrical load of the devices that will be plugged into the outlet and the capacity of the circuit. It's important not to overload the circuit, which can cause safety hazards such as tripped breakers or electrical fires. In general, a circuit rated for at least 20 amps is recommended for outdoor outlets, while each outlet should be rated for at least 15 amps.
