"I recently had Best Dressed Electric replace my doorbell chime and fix some lighting issues in my home, and I’m extremely satisfied with the service. They were prompt, courteous, and efficiently resolved both issues. The doorbell chime works perfectly now, and the lighting is brighter than ever. I highly recommend them for their excellent workmanship and professionalism. Thank you for your excellent work!"

"Received $11000 project quote for a solar panel installation with 0% finance. The quote was attractive, and I decided to go with this company. Applied for 0% financing card and got approved for it. However, after receiving permits, the company changed the contract to 6% financing option. The company insisted that the contract was originally 6%. After much discussion, it provided me with a very ambiguous and small fine prints as part of the contract. The installation was done cheap. The guys used cheap plastic pipe to get the electrical work done and also made a hole in the roof to run the electrical line through. All of these works were done without discussing it with the owner. After receiving the payments, no help or guidance for setting up SREC. You get what you pay for. I regret that I chose this vendor for solar panel project."

Great technicians who have amazing skill and are just good humans too.

Electrical questions, answered by experts

Electric water heaters use a high amount of electricity, so they’re best for homeowners who subsidize their electric bill with solar or who live in an area with inexpensive electricity. For others, gas water heaters versus electric water heaters may be the more cost-effective solution, with the added bonus of heating water quickly and efficiently. No matter which you choose, you can lower your water temperature as low as possible to keep costs down.

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).

Three-way switches work in pairs, allowing an operator to control a single light or series of lights from two separate switch locations. Most often, a three-way switch controls a light or light series in a single room.

It’s possible to distinguish a positive black wire from a negative black wire if you know what type of circuit the wires are in. If it’s an alternating current (AC), then black wires are positive. If it’s a direct current (DC), then black wires are negative. 

Sometimes, a circuit has two black wires. In that case, the positive black wire will be solid black while the negative black wire will have a white stripe on it. If you’re still unsure, you can use a multimeter to check.

A ceiling light will usually have two or three wires: black, white, and sometimes green. Black wires are positive, or hot, while white wires are negative, or neutral. The green wire is the grounding wire. 

When you’re wiring the light, connect black to black, white to white, and green to the grounding screw.
