"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!"

"After a lightning surge caused electrical issues in our house, Your Electric Solutions scheduled us much faster than other companies. Bill was fantastic! He troubleshot the issues, installed a surge protector, inspected our outlets, and replaced damaged ones. His work was neat, his prices were very reasonable compared to competitors, and he patiently answered every single question without making me feel silly. Highly professional. I’ll definitely hire them again!"

"Tolliver Electrical did a commercial job for me at Fleetpride. (a heavy duty truck parts store) The company did an excellent job in completing the electrical work before the staff reported back to work the following morning. Tolliver Electrical is the only electrical company that I call on for all my electrical needs"

Electrical questions, answered by experts

You can install a dimmer switch on almost any light as long as the switch, bulb, wiring, and wattage are compatible. Check what kind of light you have, the type of light bulb, and the total wattage of the bulbs to ensure your dimmer is a match. You’ll want to choose a non-neutral wire dimmer if you don't have neutral wiring. Homes built before 1985 that don't have updated electrical systems may not have neutral wiring.

A small sump pump running infrequently uses an average of 10 kilowatt-hours (kWh) of electricity per month. The average cost for electricity is $0.171 per kWh. The size and use frequency affect how much electricity it uses. Sump pumps average one-third to one horsepower (hp) motors. One hp is equal to 745.7 watts. Watts multiplied by the time your pump is running divided by 1,000 equals your average kWh. Multiply kWh by your average cost of electricity. In areas with high rain or a marsh basin, the average cost can be as high as $15-$25 a month.

Labor, materials, job complexity, and urgency affect costs for switches and outlets; expect from $150 for simple sets to $600+ for significant upgrades.

A piggyback circuit breaker, also known as a tandem or double-stuff breaker, combines two separate circuits into a single slot in a breaker panel. This design allows adding more circuits without a larger panel, making it a space-saving solution. Each breaker in the piggyback unit operates independently, protecting two circuits in one standard breaker slot. This is especially useful in older panels with limited space for additional breakers.

For a 200-amp underground service, you need a minimum of #2/0 American Wire Gauge (AWG) copper or #4/0 AWG aluminum or copper-clad wire. Don’t forget that, at minimum, you’ll need to use a 1 1/2-inch schedule 40 or 80 PVC conduit to successfully run a 200-amp underground service.
