"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."

Electrical questions, answered by experts

No. Do not use a 14-gauge wire on a 20-amp outlet. A certified licensed electrician would know that the National Electrical Code (as per Section 240.4(D) subsection 3) requires 14-gauge wires to be used with a maximum amplitude of 15. Therefore, you should only use 12-gauge wires on 20-amp outlets.

A 100 amp electrical service panel can't convert into a 200 amp panel simply by switching the breakers or adding circuits. Upgrading from 100 to 200 amps typically requires replacing the circuit box and updating the electrical service coming into the house. Your electrician will handle the details of the project to ensure a safe and thorough installation.

No. When applied properly, electrical tape is designed to be an insulating material with high resistance to electricity. It can reinforce electrical connections and act as a safeguard to help ensure the electrical current stays within its designated pathways. However, it’s important to note that it can break down over time and you should never use it as a replacement for electrical wire caps.

No, outdoor outlets are not required to be on a separate circuit. However, you should always defer to local electrical codes when making decisions about how to install your new outlet. An experienced local electrician will be able to inform you of all codes and requirements in place at your home.

Unless you’re a licensed electrician, you should not DIY any electrical work in your home. Working with wires and electricity is potentially dangerous to both you and the structure you’re working on, and it could lead to house fires or electric shock if you’re not 100% sure what you’re doing. There’s a big difference between changing a light switch cover and rewiring an entire home. If you’re staring down a potentially difficult electrical job, give a pro a call.
