"Jimmy was able to schedule me the same day and came in less than 2 hours. Once arrived, he checked and identified the issues and got it fixed. In addition, he installed a new outlet as well as disconnected a device per my request. Everything was done is a very professional manner. Will hire B & H Electric again."

"William, the Technician was very professional and discovered the problem right away. Then informed me that he would perform a safety check on all the electrical connections in the electrical panel free as part of the agreed on pricing. This was a really good experience and would highly recommend Mr Electric North West to anyone who need electrical help!"

Electrical questions, answered by experts

For most applications, you won’t need a neutral for 240V. There are certain codes and regulations that differ between areas so just because you technically may not need one in order for the device to function properly, it may still be a local requirement. Professionals in your area know the requirements, which is just another reason to hire one instead of taking on a project that is frankly not very DIY-friendly.

The lifespan of an average breaker box is 25 to 40 years, depending on the type and electrical events that occur in your home. Frequent power outages or surges can cause the breaker box’s lifespan to shorten. Maintain this essential electrical component by avoiding turning it off and inspecting it regularly for signs of damage.

You can make a pigtail with either thermoplastic high-heat-resistant nylon-coated (THHN) wire or non-metallic (NM) cable, often referred to as “Romex.” Each pigtail requires a neutral wire, a ground wire, and a live wire. The gauge of your pigtail wires must match the gauge of those on the device. 

Short circuits can cause significant damage to electrical appliances, bodily harm, and potentially death to humans. For this reason, they are a serious occurrence. If you’re unable to find and fix a short circuit on your own, you must reach out to a licensed electrician for help.

The most common gauge for indoor outlets around your home is 12- and 14-gauge wires. But if you’re working with larger appliances like ovens, washing machines, or dryers (all of which require more amplitude), you might find 10-, eight-, or six-gauge wires to help support those hefty appliances.
