"I had a great experience working with M&L Electrical Solutions. They were professional, communicated well, and completed the electrical work in a timely manner. They installed the exit signs and handled the wiring efficiently, and everything looks clean and well done. They also provided a referral for drywall repair, which I appreciated. Overall, very reliable and easy to work with. I would definitely use them again."

"He showed up in a timely manner. He did the job quickly. There was a shorted wire that he had to re-run and pull through the existing pipe. So far it's all working great and has not needed to return. So far everything working great."

"Gary arrived to perform the work on time as promised. He did an excellent installation job (as also mentioned by the building inspector) and delivered everything promised in his bid for the job. He was very polite and responded to all of our questions. He also did an excellent job cleaning up after the work was completed. Would definitely hire him again."

"First, they were recommended to us for the whole house generator by home depot.  We were so happy with the generator that we had him do a bathroom fan at my house and a bathroom fan at my son's house.  I did some checking and that was a reasonable price.  With the work he did, it was more than reasonable.  The job was a little more involved than he thought it would be and he didn't have any problem with any of it.  Without anything to judge the pricing from, other than online and a couple of guys I had come over who weren't on the same page as me, I'd say excellent.  The quality was top of the line.  As soon as he got the generator, he got over here to put it in. As a matter of fact, I am thinking about calling him again for something."

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.

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. 

With proper maintenance, a whole-house generator can last between 20 and 40 years. The specific lifespan depends on how often and for how long the generator is used, and some models may have their life expectancy rated in hours of operation. To maximize its lifespan, expect to spend around $150 to $300 per year for annual maintenance checks from a qualified technician. During these checks, a technician will inspect the engine filter, starting mechanism, fuel, lubrication, and coolant levels. Consulting your installer and choosing a low-impact fuel like natural gas or diesel can also help ensure your generator lasts as long as possible.

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. 

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.
