Q: Trying to determine if the lugs on the load side are two each so that they can be paralleled?
by Mike Kimler from Ohio on September 25, 2013

A: Thank you for your interest in Electric Generators Direct!

The Generac Guardian, RTSY300A3 Automatic Transfer Switch is capable of being paralleled, but not in the manner in which you intend.

These switches are designed for parallel operation in applications where there are multiple service panels coming directly off of the utility meter. Each panel would be fed with its own set of utility leads. When using multiple switches, they will be connected via the control wires, and communicate in a parallel method.

It is recommended that this configuration be performed by a qualified Generac installer.

Q: I need a 20kW natural gas generator. But they seem to only come with a 200A panel. I believe I need a 300A panel. Is there a big price difference in purchasing a 300A panel with the generator? I didn't see it on your website. Can you tell me the price?

by Peter Kearns from New Jersey on July 13, 2013

A: If you have a specific application that does not meet the prepackaged units you would purchase the items individually instead. The packaged systems are put together by the appropriate manufacturer and cannot be altered.

Briggs does not offer a 300A switch so you would need to go to the larger 400A switch if you intend on powering the entire home and that system is already prepackaged. (Model 40396).

Generac does offer a 300A switch so you would purchase the generator by itself (Model 6250) and the switch separately (Model RTSY300A3). Just add each item to the cart and enter your state and zip for the total.

We do recommend consulting with a certified electrician for proper generator sizing and installation.
