jlhmaint,
sparky66wvs Info is great and is cheaper by far then full-sized transfer switch Manual or Auto.
Transfer switch size would be based on highest current from either source so
200 amp main panel 30 amp Genset = 200amp transfer switch. Expensive and you still would need to buy more.
Reliance Makes a couple of panels 100 and 200 amp that have 2 mains 1 for Normal 1 for emergency that are mechanically interlocked so only 1 can close at a time.
UL listed for GE Square D and Siemens Breakers.
More Money then Gen Tran switch less then transfer, good solution for larger Gensets
and limited space
