  1 Question
Q: What's the maximum distance that the generator can be placed from the transfer switch? What is the length of the prewired cord and how far can it be extended?
by Howard from Washington on June 27, 2014

A: There is no specific distance stated by the manufacturer for distance from the switch.

The prewired whip is 25 feet long and you must follow national and local electric codes. So, to put it another way, Briggs & Stratton will not dictate the length after their whip because if you use the right materials, spelled out in code, there is no limit to the distance you can extend.

We recommend you consult with a "Certified" electrician who is familiar with all national and local electrical code requirements for proper installation.

Very Impressed!
Just set it up as the instructions, when it was connected it programmed itself. We have not had a power outage yet, but when I shut the main breaker, it starts immediately and transfers power smoothly
Pros: Features, Quiet, Price, High Quality

Generator seem fine. I did not like the pad for my application. The transfer switch was cheesy. All the circuit wires run right in front of the contactor, board and fuse block. The weather proof box was a waste in my application. Started right up, seem to delay on transfer when the utility returned.
Cons: Low Quality, Bad Instructions
