This is a great deal! Been looking for a double throw transfer switch for awhile now. It was too expensive so I have been holding off. Might pull the trigger on this one.
NVM.. ONLY 30AMP. I'm looking for 200amp double throw. Was about to submit the order..

You want a 200 amp?! You must have a big generator

Not for a generator but for my house 200amp service lines to this switch and connecting the 2nd throw to my inverters. I installed a cheap 200amp transfer switch from Amazon which cost me about $150 currently and want to replace it with this UL listed one.
