"I have a very good impression of Mr. Morton and appreciate his efficiency and speed in getting my generator back in service. I have asked him to put me on his list for a yearly evaluation. I am trusting that the next time there is a power failure my generator will be back in operation."

"Electrical & Security Solutions are the best! I have needed their services more than once to replace lights, a ceiling fan and also to install a new electrical box and breaker for our garbage disposal. Tyler promptly responded every time I called and he and Casey are both friendly, efficient and skillful. Aside from the excellent service, the qualities I appreciate the most is honesty for what work needs to be done and how Tyler is also very budget consciousness."

Electrical questions, answered by experts

A GFCI outlet is a type of electrical outlet that monitors the electricity flowing through the circuit and shuts off power immediately when it detects a loss or acceleration of current. They are particularly important in areas that may come in contact with water, which is why they're most common in kitchens, bathrooms, laundry rooms, and garages.

No. Blue wires and black wires are different. Even though both are used as hot wires, they serve different functions. Black wires are far more common in residential properties. They are always hot, can be positive or negative, and usually carry electricity from a power source to an outlet. Blue wires have a specialized usage in residential properties, generally as traveler wires, and are more common in commercial properties.

No, because amps and volts measure very different things. However, you can use basic equations to find amps or volts by using data about one of the measurements to calculate the other.

Professional services ensure safe installations, reliable repairs, and compliance with codes emphasizing safety in electrical networks.

Yes, you can use a 3/0 AWG wire for a 200 amp service, but only if it is made of copper, as 3/0 copper wire has an allowable ampacity of 225 amps. If you are using aluminum or aluminum copper-clad wire, you need to use at least 4/0 AWG.
