"My experience with Apollo Electric was wonderful. I needed some normal electrical work done, and also some detailed more involved work. He handled everything with care as if it was his own home. He was very detailed oriented, neat, clean and very honest. Mike worked hard during the entirety of the job, I was very pleased and I would call him for any job I need involving electrical work for the future"

Electrical questions, answered by experts

To install an outlet from existing wiring, you’ll need to choose a location where you can already access existing wiring. The easiest way to do this is to install an outlet on the other side of the wall of an existing outlet. 

Since the wiring is already in place, all you have to do is connect a new cable to the existing wiring and then connect the correct wires through the wall—to the new electrical outlet. Place your new outlet into the opening in the wall and then connect the correct wires to the appropriate terminal screws.

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.

Yes, a hot or overheating outlet is a fire hazard and can cause a fire. An outlet becoming hot indicates an electrical problem, such as an overloaded circuit, loose connections, or a faulty component. The heat from these issues can ignite nearby flammable materials like curtains or furniture. If you notice an outlet is hot to the touch, turn off the power at the circuit breaker, unplug any connected devices, and consult a qualified electrician. If a fire does start, use a Class C fire extinguisher or baking soda to suppress it, or evacuate immediately and call the fire department.

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.

A larger heater requires a larger breaker—unless there’s one already installed. The longer answer to this question is more nuanced. Do you place demands on the heater at the same time as running other heavy-duty appliances like ovens and washing machines? Do you live in an older home that may not have considered the higher electrical demands we have now? Breakers need to be sized at 125% of the load. To find that load, you should call a local electrical pro.
