Help with Surge Protection Device (SPD) Wiring

Featured Replies

Hi All,

I would like to add a Surge Protection Device (SPD) to my Sub DB.  My main focus is to protect my Inverter from surges from the Main Feed, but if possible have protection the other way too.

My Main DB already has a SPD Type II wired in parallel.

So I would like to add a Type II device in the sub DB to where the interface between Mains and Inverter happens.

I have attached a diagram illustrating my thinking.  But comments and directions will be appreciated.

PS. When I add Solar PV, that DB will also have a SPD rated for DC to deal with surges from the panels.  But that will come later.

Thanks All
