"We were so lucky to have Marella respond again to our Home Advisor Inquiry. We had used these excellent guys before and loved them , but lost their card and so we couldn't re-contact them for this project. Once again, we were totally satisfied. They are courteous, prompt, efficient, and offered us the best price for the install. Believe us, you won't do any better than Marella Electric."

Customers say: Quick response

"We received excellent service from NILES HULL, who performed a pipe repair for a hose attachment in our driveway. The job was $533, and was done well, with pleasant, knowledgeable service. I highly recommend Harris as we've used them for many plumbing and electric projects in recent years. NILES HULL was knowledgeable, caring, and attentive to detail. They stand behind their work.

Generator Install questions, answered by experts

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.

Natural gas generators are designed to run for extended periods of time, such as power outages during a natural disaster. Since there’s no limit to the supply of natural gas, they don’t need to stop for refills. However, generators do need maintenance, including pauses to check and add oil. Constantly running them will also cause a lot more wear and tear, leading to a shorter lifespan.

Generators are usually sized by running watts and starting watts. Ideally, you’ll want a generator that can offer both the necessary running watts and starting watts for everything you need to power without going beyond 90% of its capacity. Calculate your home’s electrical load based on the breakers in your home or adding up the appliance and lighting needs of connected rooms.

Many services include assembling the unit and securing it in the window. Confirm with your provider.

Generally, you’ll want to keep between 60 and 70 feet between the generator and the transfer switch. There are a few reasons for this, including:

  • The distance reduces the noise coming from the generator into your home.

  • It increases efficiency because you won’t have a voltage drop from this short of a distance.

  • Prevents carbon monoxide poisoning: keep at least 15 feet between your generator and an open window.
