I've seen some of these generator back-up systems for residential(optional backup supply),either manual or automatic, some with more than 6 circuits with no main disconnect in the equipment.If they are hard wired are'nt we required to install a main disconnect for the power supply according to 225.31?
I was looking at some of the equipment and installation instructions on www.gen-tran.com and there is no mention of installing a main disconnect.
The installation that I am designing will locate the generator remote from the dwelling behind a detached garage.
