Full Service Electrical and installation provider. If you suspect your electrical system could be damaged or malfunctioning, contact us right away. We will send a knowledgeable electrician out to identify the exact issue that is affecting your system. However, we do far more than just repairs, from LED lighting installation to electrical panel upgrade. At Kelco Electric, it's our job to make sure that all our electrical repairs are done carefully and correctly. When your electrical system is in need of repairs, it's dangerous to let the problem remain unsolved. Electrical systems are complex and interconnected, so when one component isn't working properly, the entire system is at risk. We know that your life is busy and dealing with electrical problems or upgrades isn't exactly on the top of your list. However, electrical work isn't something to be taken lightly. This is why our electricians are here to make sure you and your family are safe from electrical problems.

Generator Install questions, answered by experts

As long as your generator is used as recommended by the manufacturer, it’s safe to use for auxiliary power. Make sure that fuel powered generators are used outdoors and that the fumes dissipate away from your home. A professional generator installer will ensure your generator’s placement and set-up meets safety standards when installing or repairing your back-up power source.

As long as they have enough fuel, whole-house generators can run for weeks at a time (400 to 500 hours) without suffering too much wear and tear. However, this type of extensive use isn’t ideal if you want to extend the life of your generator.

Two important points. First, some generators may need you to periodically check oil levels every day or so and refill as necessary for safe operation. Second, if your generator uses a fuel tank, keep it regularly full so it doesn’t suddenly shut off. Many backup generators can run through a full tank in a day when they are powering large portions of a home.

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. You can connect your home back-up battery to a generator with its designated charger. Be sure that the output of the generator matches the input requirements for the battery for best results.

An undersized whole-house generator has the potential to overheat and shut down when you try to run a central AC system. This scenario can not only damage the whole-house generator, but can also trip your home’s breakers or cause electrical damage. To avoid this situation, hire a local generator installer to correctly size your whole-house generator.
