"Ted and Robert arrived, got right t to it and within a few hours we had 2 ceiling fans installed, one which had no existing light so it was a more involved project. They were professional and stuck to their original quote! To say we are impressed is an understatement. We strongly recommend using Connole Electric."

"They came out in the middle of a storm and promptly hooked the generator to my panel. While I thought I’d be running extension cords to my appliances it turned out that the whole house was up and running. I wish I had done this earlier. I would recommend MGT for any electrical needs. I will surely use them again."

"WB Lightning Rods did an excellent job installing lightening rods on our home. The owner stayed onsite the entire time to supervise the work. He took extra care to plan the rod and cable placement to ensure the proper protection and retain the aesthetics of our home. His crew were knowledgeable, polite, neat and efficient. We could not be more pleased with the results."

Electrical questions, answered by experts

Yes, the majority of appliances that run at 240v will work with a 220v outlet, but will often run slower and may have a slight delay in turning on. This could also cause long term damage to the appliance being used, so it’s recommended to always use the correct voltage for your appliance and upgrade to a 240v outlet if needed.

To avoid drilling into wire, you will need to trace your home's wiring using a stud finder, wire detector, circuit tracer, or voltage finder. Since locating wires in your home can be difficult for some homeowners, hire a professional electrician with the experience and knowledge needed to safely handle electrical systems before drilling into any walls in your home.

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.

The National Electrical Codebook indicates that there should be at least 6 inches of wiring in the breaker box for connecting purposes. When in doubt, err on the side more, because you can always cut some wire off but you can never add it back on, and if you don’t have enough you may struggle to finish wiring your breaker box properly.

Most LED bulbs have a plastic covering, while incandescent bulbs will be made from glass. This is because LED bulbs don’t produce as much heat as incandescent bulbs, so the covering doesn’t need to be as heat resistant. Also, an LED light bulb will usually have a marking on its base that identifies it as an LED.
