"This was the first time I used Angi. I needed the job done very quickly so my GC can continue his work. What were done including, replacing electrical panel, updating amp from 100 to 200, and completing a list of miscellaneous projects such as adding dimmers, replacing recess lights throughout the house. I normally only use people that I know for work around my house. To my very pleasant surprise, they did a very fantastic job. On their website, it says they are perfectionists. No kidding! I would definitely go back to them for future projects and would highly recommend Odinson."

"Fred was very communicative and flexible in helping me, my landlord and my fellow tenants work out the solution for adding a new 220V circuit and isolating some of my circuitry from the panel in my neighboring tenants office!. After understanding a relatively complex set of issues quickly he provided a fair estimate and proceeded with the job to fit the schedule of my neighbors to avoid interrupting their service by working on a Saturday. Fred arrived fully equipped and was able to finish the job in one day to my specifications and well done! Amber Electric Service is my new go to electrician. I am very pleased!"

Generator Install questions, answered by experts

A 1,500 square foot home will likely need a 15kW to 20kW generator. When deciding on whole-house generator size, add up the total wattage of the devices that you’d like to continue running during a power outage. That way, you can ensure you purchase a generator that can power your necessary appliances or medical equipment during an electrical emergency.

Whole-house generators can last 20 to 40 years with normal operation and proper maintenance. If you look up the specifications for your generator, you may be able to find a lifespan rated in hours of operation. Life expectancy will vary depending on how often and for how long you use the generator each year. Choosing a fuel with low impact like natural gas or diesel can help generators last as long as possible.

If you have a transfer switch properly installed, the generator and main electrical power cannot feed the system at the same time. However, you should still shut off the power at your main circuit breaker panel before activating the generator. If you do that, you’ll simply need to shut off the generator and reset your circuit breaker once the local power comes back on.

You may need a permit for a portable generator if you’ll be installing a transfer switch for your primary residence or similar work. Otherwise, a permit for other uses may not be necessary. Check your local building codes or ask a local generator installer for more information about your local regulations.

Yes. You can connect your home back-up battery to a generator with its designated charger. Be sure that the output of the generator matches the input requirements for the battery for best results.
