"James came out to price install of a box to plug in my portable generator. After we started talking and me asking questions James was able to give me an outstanding price on a whole house Generac generator with panel upgrade and included a whole house surge protector. They ran into additional costs with running the gas line but James kept to his word and honored the original price! The crew were professional and proficient in their work! Marcie was outstanding with communication and explaining any questions I had! I would definitely recommend this company and would use J&M for any future electrical needs!"

"Called and was scheduled for the appointment 2 days later. They called before coming over and actually arrived faster than expected. He was able to determine what was wrong with the door bells and fixed them quickly. He said he would have to trouble shoot the light fixture but suggested changing all 3 of the light bulbs. Well, that was all that was needed. Color me embarrassed. He asked if there was anything else he should look at, which was very nice. We will call them for any future electrical needs."

Electrical questions, answered by experts

Wiring or installing a light the wrong way can lead to potentially dangerous scenarios, including shock and even electrical fires. If you’re the least bit uncertain whether you’ve wired something correctly, the best and safest approach is to call in a professional electrician to handle the installation for you.

Yes, the National Electrical Code (NEC) requires that outdoor Christmas lights be plugged into a ground-fault circuit interrupter (GFCI) outlet to prevent hazardous electrical shocks or an electrical fire. It’s a code violation to plug outdoor Christmas lights into a non-GFCI outlet, so be sure to follow these guidelines for a safe and successful installation.

Yes, a dead outlet can be dangerous and may cause a fire. The lack of power can be due to a hazardous electrical issue that poses a fire risk. If you notice a burning smell, discoloration, or sparks from a non-working outlet, it is a serious issue. It is vital to have a professional electrician investigate and fix the problem as soon as possible.

Yes, one wire is always hot on the 3-way switch, meaning it carries the electricity from the power source to the switch. If you have a 3-wire cable in your home, you have two hot wires, or line wires, coming from the power source. Typically, you’d connect the hot black wire from the power source to the traveler wire and the hot red wire from the power source to the first 3-way switch. For the second 3-way switch, you’d then connect the hot black traveler wire to the switch.

There are several reasons why an electrical outlet would suddenly stop working, including:

  • Broken parts in the outlet

  • Outlet burnout

  • Circuit breaker tripped

  • Damaged circuit breaker

  • GFCI outlet tripped

  • Damaged or loose wires

  • Failed connectors

  • Appliance failure
