In my earlier post I mentioned my BCO insisted I fit a Surge Protection Device (SPD). The item arrived today and because the Surge Devices web site has some information but not the full install instructions, I have scanned the instructions in case anyone else was thinking about one and would like further information.

Is this not a contradiction:

"Connect to a 32A MCB b or c curve"
and
"You only need one arrester per board and all your outgoing circuits
on that board will be protected"

I thought the device relied on tripping a 32A MCB to disconnect that
specific circuit? Or will it take the company fuse with it?
