Transfer Switch Configuration


I have a 15 kw generator and a automatic transfer switch that came with a automatic stand by generator that crapped out on me. My question is how can I use the automatic transfer switch with 10 r 12 20amp breakers to feed my 200 amp main breaker panel as one live feed instead of 10 r 12 seperate 20 amp feeds? Rather not forking out another $600 for a manual transfer switch.

What crapped out? The generator or the transfer switch?

Does the existing tranfer switch unit have one large handle or 8 to 10 small handles?

The transfer switch unit with 8 to 10 small handles is actually a combination of 8 to 10 small transfer switches and one subpanel all in one unit. It can back feed the main panel as a whole only via one (120 volts) or two (for 240 volts) of the small switches each of which is limited to perhaps 20 amps, possibly 30 amps.

This transfer switch unit is meant to handle 8 to 10 selected circuits in your main panel and the panel bus bars and the rest of the branch circuits remain dead during the power outage.
