"From estimate, to selection of The Juice Company, to scheduling, they made the entire process painless. Had 2 15 amp "peanut" breakers installed to replace an existing breaker and establish a new circuit, and 2 new outlets installed. We also had low voltage network cable roughed in so I could terminate it later, and everything was done not only properly, but quickly. I would definitely recommend them to anyone needing electrical work done in the South Sound region."

"I had told them I would be buying an EV and they said to give them a ring when I was ready to install the charger. Bought the car on Saturday, called them on Monday, installed on Thursday with no drama, apparently excellent workmanship, and in a timely manner. They were even able to do it without disturbing our internet access despite having to move breakers around."

"We had In-House Electrical replace/upgrade our main panel as well as setup a generator hook-up and A/C outlet outside. Adam and Avery were phenomenal - they were thorough, kept in constant communication with me during the project to ensure things were being done as I liked, and left the place looking better than when they showed up. They'll be my first call in the future for any electrical work I need done."

"I called Voltlab and Evan Cade to advise me on what to do about some ungrounded outlets in my house. After helpful discussion during a complimentary inspection of the rest of my electrical system it was clear I needed serious attention to more than a few outlets. What I thought would be a simple service call turned into a service upgrade and partial rewire. Though I was surprised with the amount of work required to bring the house up to code, Evan's obvious knowledge and straightforward approach to the work made me comfortable trusting Voltlab and Evan with the project. About 9 days of work was spread over a month from first visit to last inspection and all went smoothly. Evan coordinated scheduling with city officials and inspectors and kept me informed at all times. His crew of electricians did a great job and respected me, my home and property. They are a talented and very experienced team. Evan is rightfully proud of the company he is building. Highly recommended."

Generator Install questions, answered by experts

Whole-house generators need to be installed on level ground several feet away from walls and other objects. Because they tap into the electrical system directly, they usually need to be close to your home electrical panel for a transfer switch installation. It also helps with installation if they are near to a gas line or propane tank installation.

It is safe to run a generator continuously, but you must follow safety protocols to ensure personal and home safety. Read the manufacturer’s instructions for specific recommendations, but the general recommendation is to turn generators off overnight or when you’re away from the house. Overworked generators can pose a fire hazard and if your generator is not in a well-ventilated area, running it continuously could lead to carbon monoxide poisoning.

A 10,000-watt generator can run a small to mid-sized central AC unit (typically up to 3 tons or 36,000 BTU) along with a few other appliances. However, larger AC units or additional loads will require a bigger generator. Consult a local generator installer to ensure you add the correct size generator to your home.

It might seem counterintuitive, but installing a generator transfer switch will save you money in the long run. While you’ll have to pay between $400 and $2,500 to have the transfer switch installed, you’ll recoup that amount later on when you don’t have to pay for expensive repairs to your appliances, devices, and electrical system that may have burned out, overloaded, or stopped working due to a sudden loss of power or an incorrect hook up of a generator to your home. 

Sizing a generator is a careful process that requires calculating the electrical load of your entire house. You have to take into account every device you want to use and their wattage requirements, plus the wattage needed to start them, and look for a generator that can safely run all that at around 80% capacity.

In more practical terms, a small home can run on a 10,000-watt generator (and if you only want to power a few key appliances, much less than that). A mid-sized home may need something between 15,000 and 22,000 watts. Larger homes require 25,000 watts or more.
