"Good service. Got reminders of technician arrival day and time. Call from dispatch on day of service. Fantastic technician. Took me through what I saw as needs, made suggestions that I had no way of knowing that made way more sense. Provided thorough analysis of our home electrical service and made corrections along with suggestions for what next service improvement could be after this completed job. Most important, when work was all done it got a big smile of approval from my wife. Super deal. Will call on them again."

"I was contacted by a Tech at the assigned time and had to run to the store for a cable I needed. When I called back, I had a different Tech, but he was able to continue right where I had left off. There was no need to explain anything again. Awesome."

"There were many things wrong in my computer (my fault and letting grandchildren on computer) Robert was so helpful, gave me many good instructions to keep everything safe, which I have written down, feel like I have a new computer. He was so excellent and experienced, took his time and was meticulous about what needed to be done. He was a pleasure to work with and I will use this company again! Linda Disy"

Electrical questions, answered by experts

Different types of light switches include single-pole switches (the standard switch in your home), double-pole switches, toggle switches, three-way switches, four-way switches, dimmer switches, and more. 

A single-pole light switch controls the power to a single device, whereas two-way, three-way, and four-way light switches control lights from different locations, increasing the number of connections in the home.

Removing a fuse from the fuse box is relatively safe under normal circumstances. The task becomes dangerous if wires or wire terminals are exposed or in the case of a disaster such as flooding in the home where water can act as an electrical conductor.

Most people don’t think twice when using loose outlets, but they are a safety hazard. Loose outlets can cause issues with the flow of electricity in your home, resulting in electricity jumping from one connection point to another. When this happens, it can cause a spark that could start an electrical fire in your walls.

240V is the standard for more demanding appliances in the United States, whereas 220V is more common elsewhere. The voltage isn’t very different in any practical sense. The United States is a newer country compared to many other regions in the world with a faster adoption of new electrical needs. Appliances in the United States are often bigger than other parts of the world.

Incorrectly wiring a single-pole switch results in the connected light or device not turning on or tripping the circuit breaker. Although it doesn't matter which terminal the hot wire and the load wire connect to, mixing up a circuit wire with a ground or having loose connections can prevent the switch from working.
