"These guys were super professional and easy to be around. Were good at explaining what they were doing so i could understand.  Didn't ruin my garden where they were working outside the house.  Every time they came in the house, they put on little scrub-type-booties over their workboots!  Owner, John, brought them lunch, then stayed to inspect and personally help with labelling the new electric panel (which many electricians fail to do at all).  I highly, highly recommend these guys.

"Mike came to give an estimate and was able to meet a short timeline as I needed 2 electrical outlets installed before the plumber came to install the water heater. Elliott came and got the job done on time and did good work. Elliot was very professional."

"JDV Electric recently replaced my electrical panel and delivered outstanding service from start to finish. The technicians were professional, courteous, and extremely knowledgeable. Before beginning the work, they took the time to remove the panel cover and thoroughly explain the existing damage, as well as how to prevent similar issues in the future. Unlike other companies that simply provided quotes without any explanation, JDV made sure I fully understood both the problem and their proposed solution. Their attention to detail and clear communication set them apart. The team worked efficiently and left the work area spotless, it was as if they had never been there. It?s rare to have a contractor complete a job without needing any cleanup afterward. I highly recommend JDV Electric for any electrical needs, and I will absolutely be using them again for future projects."

Electrical questions, answered by experts

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.

To determine if an electrical outlet is blown, look for visible signs of damage such as a burning or smoky smell, burn marks, or a melted or discolored plastic cover. If you notice a burning smell, contact an electrician immediately. Other signs include a plug that keeps falling out or the outlet not working when you test it with different devices. For further troubleshooting, you can use a voltage tester or multimeter to check for power; a reading of zero indicates a problem. Also, check your circuit breaker or fuse box to see if the circuit was tripped and reset it if necessary. If these steps don't resolve the issue, the outlet may need to be replaced.

If you strictly adhere to electrical safety rules, including assuming that a circuit is hot until proven otherwise, and have some knowledge of how an electrical circuit works, you can likely replace a light switch by yourself without too much trouble. However, it's always advisable to call a nearby electrical pro to do the job if you're unsure of any steps necessary to change a light switch. 

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.

Switching the hot and neutral wires in an outlet or receptacle, a condition known as reverse polarity, is dangerous. While the outlet will still function and provide power, it creates a significant electrical shock hazard because anything plugged into it will remain electrified even when switched off. If you touch a conductive part of the appliance, such as the metal components of a toaster, you could receive an electric shock.
