I have an application where a client has been getting some control boards burning out on some mini-splits. He requested that we had a TVSS (SPD) for the condenser only, not on the panel feeding the condenser.
Right now, there is a 20A, 2-pole non-fused disconnect feeding the condensing unit. Is there a product out there that could maybe mount to the side of the N/F disconnect and connect to the line side of the disconnect? Something approved specifically to protect a single piece of equipment retroactively. This is kind of tough because normally the manufacters data recommends #10 wire with a 30A circuit breaker but I only have a 20A probably fed with #12s.
I dont really like this whole idea. Maybe its just better to advise him to install at the panel? Either way, curious to know.
