I have a 100-Amp 240-Volt Outdoor Non-Fused Transfer Switch and would like to wire it to the main panel outside. My main panel has 3 breakers (Oven [25 Amp], A/C [50 Amp], & House [100 Amp]) my desire is to tie the Transfer Switch into the service entrance wires that run from the main panel to the sub panel in the garage. (Diagram Below) I already own the hardware so I want to utilize what I have if I can, but don't want to look like a complete idiot when I get someone out there and they go "you can't do that!"
(Note: I plan to hire an electrician to actually wire this up)
I guess my questions are:
- Can this be done this way?
- Do I need a downline protection device (30-Amp 2-Pole Circuit Breaker) between the Generator and transfer switch?
- What are the pitfalls of doing it this way? (aside from the potential for the house to pull more than 30 Amps on that line and pop the breaker.)
