"Daniel from Imperial Electric did an excellent job for us. We had a relatively small issue that he rectified for us very quickly and then did a very thorough inspection of our entire house at our request. He made a number of recommendations to upgrade our old electrical system that were practical, reasonable and in line with current codes."

"Pete was very nice and he was very knowledgeable about his job. I would recommend Watts Electrical to my friends and family. Pete gave my son in law a great idea and explained how to do it, he said that it was a good idea to save money, they just bought the house and he was very very nice. He did not make it the day before but he called to reschedule and he showed up the next day and was very quick to find the problem and explained how to fix one. We would recommend him for all of your electrical needs."

"My experience working with Carlos at Enable Electric was seemless. Carlos was extremely attentive with communication, on time for visits and completed my electrical panel swap successfully. I highly recommend Enable Electric and will most definitely be hiring them again for additional projects in the very near future!"

Generator Install questions, answered by experts

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. 

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.

It is safe to run a generator continuously, but you must follow safety protocols to ensure personal and home safety. Read the manufacturer’s instructions for specific recommendations, but the general recommendation is to turn generators off overnight or when you’re away from the house. Overworked generators can pose a fire hazard and if your generator is not in a well-ventilated area, running it continuously could lead to carbon monoxide poisoning.

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. 

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.
