"Jordan Blake from Exceptional Electric rocks! His communication prior to coming out was very thorough, and he was able to schedule us in two days. While he was onsite he found multiple items from years of DIY wiring, one major one. He clearly communicated al recommended changes to better match current code. As to the major item, he discovered the transformer was causing over-voltage delivery into our main! He had me call United Electric, and the linemen were out even before Jordan left – kudos to U.E. Cooperative – and replaced the transformer on the pole. All this for what started out as just putting a new 30A circuit in for a mini-split! Our mini-split is not yet on site, so we look forward to having Jordan back to the farm to complete the electrical plus a couple of the found issues next week. He is so knowledgeable. I highly recommend him. His sense of humor is also a delight, and my husband enjoyed learning and discussing many things with him. His prices are excellent."

"My wife says Iâ m â particularâ â ¦. ð Iâ m not sure Iâ m particular, I just expect contractors to do exactly as agreed and to do a good job just as they would want! Farm Creek Electric did exactly that on our electrical job north of Cameron, MO! We had a line ran 200â and two RV boxes installed with 50, 30, and 20 amp plugs installed. Dean communicated well, knew exactly what I wanted after telling him one time, completed the job quickly, and honestly exceeded my expectations!"

Generator Install questions, answered by experts

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. 

Costs depend on generator type, labor, and additional wiring or transfer switch requirements.

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.

No, you should never plug a generator directly into a wall outlet in your house. This practice is extremely dangerous, often illegal, and can cause "back-feeding," where power from the generator flows back into utility lines, creating a life-threatening hazard for utility workers. It can also damage your home's electrical system, including appliances like pumps and HVAC fans. If the main power is restored while the generator is connected, it can destroy the generator and cause an electrical fire. To safely connect a generator, you must use a professionally installed transfer switch or an interlocking kit, which prevents back-feeding by disconnecting your home from the utility grid before the generator provides power.

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.
