Surge Protector - Before or After Transfer Switch
I am pretty sure that this has been discussed somewhere, but I can't find it and I don't think it's been the main subject of a thread before.
I am getting ready to install my hardwired surge protector. I have leftover #6 wire to connect the transfer switch to the surge protector so it doesn't matter where the outside cable connects.
1. Should I connect it after the transfer switch. This protects the electrical system from both shore power and the generator, but leaves the transfer switch itself unprotected. There's not much that can hurt a transfer switch, other than high voltage to the coil on the relay.
2. Before the transfer switch: Protects the switch, but doesn't protect against faults from the generator. What's the likelihood of the generator causing a problem?
What's your opinion?
