I offer troubleshooting, running new wire or conduit for electrical, and replacing existing devices

"After finding ETM Electrical through Angi, I contacted Eric at ETM. He responded that morning and arrived at my home promptly the same afternoon. There was no power going to my sprinkler controller box. Eric found the breaker and rewired my box, all within 15 minutes. He cleaned up my wiring, reinstalled my box and now I'm good to go, and all for a reasonable price. Thanks Eric! I would definitely use ETM again!"

Generator Install questions, answered by experts

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.

In some situations, yes. Never try to put biofuel into any home generator without checking the specifics first. If a generator has the ability to run on diesel, it can also run pure biofuel (the clear kind made from seed oils, for example). But if you are using biofuel made from animal fats or vegetable oils, the generator will need significant modifications before it can handle a sludgier type of biofuel.

You can expect a diesel generator to last for up to 30,000 hours of use, which works out to 20 to 25 years with the proper maintenance, of course. That depends on how much you use it, so a diesel generator used for emergencies a couple of times a year will last a lot longer than a generator that takes over for a faulty electrical grid every month for a day or two. 

When properly maintained, natural gas generators can last a long time, as much as 20 to 40 years. They have relatively few needs compared to generators with other fuel types. However, the generator’s lifespan ultimately depends on how often the generator is used and for how long it’s left running.

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.
