"I would highly recommend Naymar Electric to anyone looking for an excellent electrician. Their prices were very fair and competitive, their estimated timeframes given were more than reasonable and turned out to be accurate. I appreciated that David was readily available to answer my basic questions, as well as use his experience and creativity to wire the house in a way that would provide for future inhabitants and household configurations. He was very knowledgeable and informative, as well as creative and aesthetic, and he and his crew were hard workers that paid attention to detail and left the house easy to patch when they were through. I am so glad I went with Naymar Electric, they are now my go-to!!"

Electrical FAQs, answered by experts

The size of the microwave you choose may change this answer, but for standard over-the-range microwaves, 120 volts and a three-prong grounded outlet is needed for your device.

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.

If you connect the wrong electrical wires together, it can lead to a very dangerous electrical shock. All wires should be matched with wires of the same color. It’s very important to consult an electrician if you’re unsure about how to wire your fixture.

Usually, a light switch goes bad due to normal wear and tear. Light switches are mechanical devices with internal moving parts. These parts make contact with each other, and, over time, the friction can wear them down, causing the switch to feel loose, arc, or fail to operate. 

There are several indicators that a single-pole switch is bad: the switch is warm or hot to the touch, sparks are sometimes present when turning the switch on or off, you hear a buzzing sound or other weird noise coming from the switch, the connected light flickers when you turn on the switch, and the light doesn't turn on at all with the switch. If you notice any of these, replace the switch or call a pro straight away.
