Generator Install questions, answered by experts

While diesel is relatively stable, it won’t last nearly as long as propane and you may have to replace it if it sits unused for too long. Diesel can sometimes struggle to work efficiently or start engines during especially cold weather, so it’s not the best choice for every climate. Compared to fuels like propane and natural gas, diesel generators tend to be noisier and create more exhaust, which isn’t always ideal for home use.

Generators are usually sized by running watts and starting watts. Ideally, you’ll want a generator that can offer both the necessary running watts and starting watts for everything you need to power without going beyond 90% of its capacity. Calculate your home’s electrical load based on the breakers in your home or adding up the appliance and lighting needs of connected rooms.

You may need a permit for a portable generator if you’ll be installing a transfer switch for your primary residence or similar work. Otherwise, a permit for other uses may not be necessary. Check your local building codes or ask a local generator installer for more information about your local regulations.

You can determine what size generator you need by listing the various appliances it will power during an outage. Write down the start-up watt usage, and then add them all together. 

A 7,500-watt generator will run your refrigerator, freezer, well pump, and lighting circuits without a problem. However, you’ll need an extra 3,000 to 4,500 watts to run your water heater and another 5,000 to 25,000 watts to run your electric furnace. In these instances, a whole-home generator is your best bet for running your critical equipment.

You can determine what size generator you need for a transfer switch by matching the switch to the largest outlet on your generator. Larger generators can power up to 10 circuits, while most 5,000-watt generators can provide power to six circuits. So, if your generator’s largest outlet is 30 amps, you’ll need a 30-amp transfer switch.
