"I came home on a 90 degree day with half my bedroom having no electrical including AC. He called me right back. He went through and fixed the problem and explained everything along the way. The price was very reasonable. I would absolutely recommend him to anyone needing electrical work. Didn't push anything extra either. Great guy too!"

"Dustin is a reliable, easy-to-work-with, knowledgeable professional and I would recommend him to anyone! He quoted us a very fair price for a generator hookup and interlock kit installation, and was pleasantly surprised at how competitive his pricing is. He showed up exactly on time, maintained excellent communication throughout the process and 100% stands behind his work. If I need more electrical work done I will certainly be contacting Dustin again!"

Electrical questions, answered by experts

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.

Many wire nuts can accommodate three wires of various gauges; you should check the packaging of the nut to confirm you are buying the correct size. In addition, there are screw terminals that accommodate various numbers of wires; these might also be called “terminal blocks,” and exist to connect multiple wires. 

Outdoor outlets should be at least 15-amp, but preferably 20-amp. The exact rating will depend on the electrical load of the devices that will be plugged into the outlet and the capacity of the circuit. It's important not to overload the circuit, which can cause safety hazards such as tripped breakers or electrical fires. In general, a circuit rated for at least 20 amps is recommended for outdoor outlets, while each outlet should be rated for at least 15 amps.

There are several tools available to help prevent electrical fires. First, ensure that you have GFCI outlets installed in necessary areas, along with an AFCI, which is a circuit breaker that can help prevent arc-faults. Investing in surge protectors is also wise, as they can safeguard your appliances and other items against power surges that may overload your outlet and cause sparking.

A Tesla Powerwall comes with a standard 10-year warranty that guarantees the unit will provide at least 80% power during this period. After this time, a Powerwall may continue to operate, even if at a reduced capacity for another 10 to 15 years. Other factors can affect the long-term performance and durability of your Powerwall, such as energy consumption and how often you charge the battery.
