Should a whole house surge protector be installed with a dedicated breaker or is an existing one okay. Also, should you use the same brand breaker and protector ?
Both ways are correct way. As long as an existing is a two pole breaker. But is must be dedicated to only that. Never should you have more than one circuit on a single breaker. You really want the breaker at the top, The surge protector should be at the very top of the panel for it to protect everything below it. It does not have to be. But all of mine are SquareD, that is the same as all the panels I have.
