"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!"

"Excellent customer service after the sale. Electrical component failed on a Sunday morning, placed a service call and a real person answered. Received a return call from a technician quickly, 30 minutes later they were in our driveway. Diagnosed the problem, completed repairs, very friendly and smiling. Total time from making the call to repairs being completed less than 90 minutes. Thatâ s INCREDIBLE in todayâ s world."

They arrived at the house at the agreed upon time, were respectful of my property, explained the process and completed the work within the specified time frame. They were pleasant, easy to work with and installed a quality lightning rods system. I highly recommend them."

"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

Yes. A pellet stove should have its own 110V outlet and dedicated circuit breaker. Otherwise, it could overload the system. Pellet stoves can create major fire hazards if they aren’t wired properly or have to share circuits. Get in touch with a local electrician or pellet stove expert if you need to run new wiring for a pellet stove.

Different fences use different amounts of electricity, but their operating costs are very low overall. Electric fences pull between 4 and 25 watts from the system if you have an average-sized yard. Barring any complicated math, you can expect an average electric fence to cost less than $5 a month to run. Aboveground electric fences, which are not typical for residential use or small animals, can cost more, but you shouldn't notice a significant change in your electric bill. 

No, technically, the original Federal Pacific (FPE) breakers are no longer available. Stab-Lok® circuit breakers from the now-defunct Federal Pacific Electric Company (FPE) are no longer produced. However, the trademark and manufacture of the Stab-Lok® brand of breakers has been passed through a series of parent and subsidiary companies. Black and gray versions of the circuit breaker have been produced by these companies, with sales rights in the U.S. and Canada shifting back and forth.

When selecting a pool heater, it’s important to think not just about the cost of the unit itself but also about how much it costs to run. Expect to pay about $100 per month to run a heat pump pool heater. A natural gas heater will cost twice that amount, while an electric pool heater costs about $250 a month.

The American Wire Gauge system calculates wire size diameters using the complicated formula D(AWG)=.005·92((36-AWG)/39) inch. A simpler rule of thumb is that every six-gauge decrease doubles the wire diameter, and every three-gauge decrease doubles the wire’s cross-sectional area. On the other hand, wavenumbers are typically measured in reciprocal meters (1/m or m−1) or reciprocal centimeters (1/cm or cm−1).
