"Mike re-wired my basement outlets at my apartment. He figured out that all of them were wired incorrectly. Not only did he restore power to my basement outlets, he prevented an electrical fire from the previous incorrect wiring. He also installed a new bathroom fan/light combo, with Bluetooth speaker capabilities and multiple led light colors. He was efficient, fairly priced and honest. Highly recommend! Thank you again Mike!"

Electrical questions, answered by experts

Volts and watts aren’t directly convertible units—they measure different aspects of electricity. Volts measure electrical potential, while watts quantify the power. The relationship between the two is defined by the equation: Power (watts)= Voltage (volts) x Current (amperes). In other words, the product of volts and amps results in watts, but there is no fixed conversion of volts into watts.

Most household circuits can handle about 70 strings of 50 standard mini lights, or up to 600 strings of LED lights, which consume less power than the incandescent variety. Make sure to factor in any appliances also running on the circuit.

Modern homes have a lot of devices and appliances running at once. That means there are many different wires and cables throughout the house. Service entrance conductors (also known as service entrance cables or service feed wires) connect the external weatherhead for the utility pole to the circuit breaker box. This is your home’s connection to your local power grid.

Yes. You should always turn off the power to the work area before beginning, use a voltage tester to ensure it’s off, and wear protective gear, such as insulated gloves or safety glasses, to prevent risk of injury. Proper wiring and grounding techniques are also necessary to make sure the job is done right the first time and won’t harm any future homeowners. 

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.
