Electrical Question: We would like to install a Generac Guardian 20k with the 200amp Nexus Smart Switch.
We are trying to determine the cost of the electrical generator hookup. We already have prices for the gas hookup and town inspector.
The estimates we get for electrical hookup are for generator installation companies who gave us a range of $4000 to $7000 depending on the company. This seems ridiculous. Is this a rip off or is this reasonable?
How many man hours should hookup takes.
The cellar is open (no sheet rock in the way for cabling) and it’s a 200 amp service.
Any guidance on how we find a reasonable and qualified electrician.
Thanks for your help,
Michael

Thanks for your electrical wiring question Michael.

Michael, the cost of the generator installation will depend on a lot of things, such as listed here:

How to Estimate the Cost to Install a Home Generator

Factors that will Effect the Cost of a Home Generator Installation
1.) The location of the generator.
2.) The home electrical panel.
3.) The number of circuits you wish to have on generator power.
4.) The location of the fuel source.
5.) Access to all of these items which will have a impact on the time and materials required for the home generator installation.

Type of Fuel and the Amount of Fuel that will be Available for the Generator

More frequently are we hearing about wide spread storm related power outages that can leave us in the dark for days, so it would be wise to consider how much fuel will be available for your generator for extended hours of operation.

Fuel Considerations and Hours of Operation of a Home Generator
The gas or fuel tank that is standard equipment for the generator will only last for a certain number of hours which will depend on the size of the generator and the amount of electrical load that will be placed on the generator. Find out how long the generator will run and then determine how many spare fuel tanks you should have on hand and where they can safely and securely be stored.

Propane or Natural Gas Generators
If  you have natural gas or a propane tank at your home you should consider a generator that runs on this same type of fuel, that way the generator will operate for an extended period of time without the need to be constantly refueled. If you have a fuel tank on site, such as a propane tank, make sure it is filled up often, especially before winter weather sets in. If you experience power outages quite often then you might consider replacing the size of the fuel tank.

Dual Fuel Generators
Some generators may offer the option to operate with two different types of fuel, such as gasoline and propane or natural gas. This can be very handy when one fuel source becomes depleted but the alternative fuel is available.

Local Standards and Ordinances
Be sure to check with all local organizations that may affect the type of generator before making the final decision about the right generator for your home at your specific location. Make sure that the generator is installed with a perm,it and receives all applicable inspections.
