  1 Question
Q: Can you give ma a general idea on how to install the auxiliary transfer switch contact kit. I do not want one of my AC unites being protected by my backup generator.

I also want to buy the briggs riggs & Stratton 16kW Standby Generator System (200A Service Disconnect + AC Shedding) 4299. I need the front exhaust system for placement. Is this the best choice if I must have a front exhaust unit?

Anything I need to know?

Can you offer a better price or do you have any promotions on that unit?

by Ralph Cabage from Tennessee on September 21, 2013

A: You cannot use the Generac Guardian Auxiliary Transfer Switch Contact Kit with a Briggs & Stratton generator, they only install into the Generac whole house style transfer switches. Here is the installation instructions.....

Installation Instructions

Briggs & Stratton have the only models that exhaust out the front of the generator.
