"Sergio and his assistant installed an EV charger at my place, and they did an amazing job. I’m so glad I hired them. Their price was reasonable compared to other contractors. I highly recommend them and would definitely use their company again for any future jobs."

"We hired ADI Electrical on 2/5/24 to do 5 different electrical jobs on our home, replace a fixture under the cabinet in the kitchen, supply and install floor outlet in the family room, supply and install new outlet for the garage ceiling, remove outlet in an old furnace closet, install new doorbell by move existing doorbell transformer to attic and fish ethernet cable from attic to junction box on side of house. Alvaro gave us a detailed estimate on 1/26 and we like their website which is very thorough and precise in its presentation. Michael the administrator in the office was very helpful in setting up appointments and anything else that was needed. Santo, Alex and Sam Adi came out on 2/6 to do the electrical work and we are extremely pleased with their attentiveness to detail and accomplishing everything that needed to be done. All the areas were cleaned up and everything was left spotless. We are very satisfied with the electrical services, and we highly recommend them."

Generator Install FAQs, answered by experts

You can determine what size generator you need for a transfer switch by matching the switch to the largest outlet on your generator. Larger generators can power up to 10 circuits, while most 5,000-watt generators can provide power to six circuits. So, if your generator’s largest outlet is 30 amps, you’ll need a 30-amp transfer switch.

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.

Yes, in some locations, it is required by the National Electric Code (NEC) to have a transfer switch installed for electrical emergencies. In addition to following electrical code, generator transfer switches ensure your home is fully protected during a power outage. By switching the power from the main breaker to the generator breaker, you can seamlessly operate your HVAC, lights, appliances, devices, and more during an emergency. 

DIY is possible for basic setups. Professional installation ensures safe and proper electrical connections.

To reduce AC startup power for a whole-house generator, install a soft start kit or hard start capacitor, which lowers the initial surge by gradually ramping up the compressor. Using a smart load manager can also help by staggering startup loads, preventing a system overload and future costly repairs.
