How to Install A Standby Generator with Automatic Transfer Switch?

Step 1 – Install the generator from all windows and doors at least 5 feet away.

Step 2 – The generator must be placed on a casted concrete pad because of its vibration.

Step 3 – You can then secure the generator on the pad with four strong steel bolts.

Step 4 – Contact a plumber to connect a natural gas line to the generator. That will be its source of fuel.

Step 5 – Run a line-voltage cable to the generator. This is the job of an electrician. Don’t do this yourself if you’re not a certified electrician.

Step 6 – Install a transfer switch near the electrical meter. The function of the switch is to direct electricity from the generator into the house when the generator starts working.

While we encourage you to do a lot of tasks yourself, we don’t think the installation of a standby generator is among. It is better to hire an expert for the installation. Don’t risk the wrong installation.

How Much is An Automatic Home Standby Generator?

Remember that standby generators come in various sizes, designs, and outputs. The most important factor that determines the cost of a generator is its power output. The higher the power output, the higher its cost will be, with all other factors being equal.

For instance, a 22KW generator will cost you more than a 20KW generator. So, if a 20KW can power all your appliances, you don’t need to pay more for a generator with a higher capacity.

The second factor that affects the cost of generators is size. Bigger generators are more expensive than smaller ones. Also, generators of popular brands are costlier than generators built by little-known brands. That being said, we can safely say that the prices of automatic generators begin from $6,750. There’s no cap to it.
