"Omesh exhibited his excellent electrical surgical skills while working on my electrical problem. The hallway lights in my apartment building were out and I needed them fixed quickly before nightfall so my tenants could avoid injury walking down darkened staircases. Omesh arrived without delay; completed his work quickly and now my hallway lights are working fine. The cost was very reasonable compared to quotes by other electricians. I highly recommend Omesh and G & R Electrical Contractors."

"As a Building & General Contractor myself Newgrange electric is one of my best electrical sub contractors. Eddie the owner is very hard working. Always reliable, extremely professional and maintains an office manager Nicole who knows what's going on, on all their projects so you always have someone to contact during business hours. Eddies crew is based of long time employees that are very knowledgeable in there work. Eddie will always get back to you even after business hours, which is not the norm for many vendors. We need more contractors like this. Joe Algeri, Orchard Builders & Construction & Skyline Plumbing & Heating."

Electrical questions, answered by experts

Dehumidifiers typically use 300 to 700 watts of electricity per hour, whereas portable dehumidifiers use about 40 watts per hour. The exact amount of electricity your dehumidifier will generate depends on its capacity and energy efficiency. Generally, higher-capacity dehumidifiers generate more electricity than lower-capacity units, but they also usually have better energy efficiency over the long run.

How far you can run underground electric depends on the wire gauge (generally AWG) and the circuit voltage. Too much voltage drop in an electrical circuit can negatively affect performance, so the smaller the voltage drop, the better. Ideally, it shouldn't exceed 3%. The smaller the wire and the longer the run, the more significant the voltage drop. 

For example, with a 120-volt circuit, you can run 60 feet of 12 AWG cable without losing more than 3% voltage. With a 240-volt circuit, you can run 120 feet of 12 AWG wire while maintaining a voltage drop of 3% or less.

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.

Three-way switches are only replaceable with three-way switches. A single-pole switch won't work if you replace one or more of a pair of three-way switches. By electrical code, three-way switch configurations are necessary at the top and bottom of a staircase between residential floors.

Yes, the majority of appliances that run at 240v will work with a 220v outlet, but will often run slower and may have a slight delay in turning on. This could also cause long term damage to the appliance being used, so it’s recommended to always use the correct voltage for your appliance and upgrade to a 240v outlet if needed.
