Title: Installing generator transfer switch -- question
Post by: john6221 on July 28, 2018, 01:42:27 PM
I'm a little confused about the transfer switch that I bought (got it new, never-opened, from Craiglist for $75). It is a kit, so it comes with two switch boxes (it's an older Generac system, it comes with 2 transfer switch boxes rated for 7200 W each, 6 circuits per box, 1 circuit for 240V), the outdoor outlet, and a generator cable. The outdoor outlet and generator cable are both wired for a 50-amp outlet (L14-50). 

Here's the problem--I can't install both transfer switch boxes. I don't have enough room next to my electrical panel. The previous owner finished the basement in the 70s and the walls do not give me enough room to mount both switch boxes. I am assuming that it would be OK to mount and use just one, right? I don't need more than 6 circuits anyway. I would use the outdoor outlet that came with the kit. 

It is this kit but it has two transfer switch boxes and a 50-amp outdoor outlet instead of 30A. https://www.amazon.com/Generac-Portable-1276-Discontinued-Manufacturer/dp/B00004WHKK/ref=cm_cr_arp_d_product_top?ie=UTF8

I'd call up a local electrician and have them answer your questions.  This is something that, if you're doing it properly, will require pulling a permit, and then what matters is "What the inspector thinks is legit."

This sits between your panel box and the circuits, or energizes full phases between your panel box and the feed?

I can't imagine a situation where an inspector would 1) expect a second box, and 2) have any reason to ding you.  I've personally only seen installations with one transfer switch and box.
