"Very professional. Prompt responses to all my questions both in person and over email. Electrician arrived on time for both the circuit installation as well as meeting with the city inspector for permit sign off on the follow-up appointment. Installation work was very clean and neat since I am very keen on attention to detail. Highly recommend!"

"The electrician responded promptly and gave me estimates for several different ways to solve the problem. The work was done quickly - it looks beautiful and he answered questions about several other issues in the house. He even changed the light bulbs in a very tall chandelier for me! I expect to be calling him again for another project."

"Ray was instrumental in upgrading the electrical in my townhome, including installing new recessed lights, light fixtures, replacing receptacles with new ones and modern cover plates. He also relocated and installed a new subpanel providing dedicated circuits to appliances and the newly installed recessed lights. Ray is incredibly knowledgeable and very easy to work with and I would recommend him and happily use his services again."

Generator Install questions, 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.

Here’s what you can run with different wattages and types of generators:

Portable generator:

  • 2,000 watts can handle a large appliance like a freezer or refrigerator, plus a few smaller items like phones or computer chargers. 

  • 4,000 watts will keep two large appliances operating and a few smaller devices.

  • 8,000 watts should power most essential appliances and other devices, including a sump pump, well pump, or your dishwasher.

Partial to whole-house generator:

  • 20,000 watts and above will make it seem like your home’s power is still on.

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.

If your home already has a grinder pump and you’re still noticing issues (like frequently clogged toilets and sinks), it could be time to upgrade your grinder pump. Start by checking your existing horsepower. If there are four or fewer people living in your home, using a 1/2-horsepower grinder pump should be sufficient. Larger households should consider investing in a 1-horsepower grinder pump to maximize wastewater removal efforts.

To power a central air system during a power outage, the whole-house generator will need to be at least 5,000 watts, and this number will significantly increase for larger units. Check the specific wattage requirements of your AC unit to choose the right generator size. Consider consulting a generator installer to ensure your whole-house generator meets your electrical load needs.
