I did have to move some breakers around so this would be close to the top of the buss and on the left hand side of my breaker panel. This was the only side I had access to. Unfortunately, there was a stud next to that side as well. Using an oscillating multi-tool and hole saw, I was able to cut the needed opening to install the surge protector within 6" off the new 50A breaker. My breaker box is flush mount and so is the surge protector. I wanted to buy the cover plate, but I refuse to pay $25 for something like that. I will fabricate my own.
Will it worK? Who knows, but after taking a big hit from lightening to a tree close to the house, I'll try anything. The specs sure seem to say it will. That said, I lost 3 cordless phone sets from this hit. It literally blew the cover open on the box where the underground telephone wires enter the house. I'm fairly certain this surge protector would not have saved the phones, but if it could have saved the 2 TV's, DVD player and dishwasher, it would have been well worth what I spent for this device. We'll see.
