Next week I've got a single phase CU change that's a sub-main fed by an over-air cable run supported by catenary wire.
By rights I believe this should have a Type 1 SPD.
My normal go-to board (Fusebox) doesn't seem to list a Type 1 device in their catalogue.
I wondered if anyone can suggest any of the mid-range boards that has a Type 1 device available.
Secondly, can I take as face value what Surge Devices told me - they reckon it was fine to fit one of their devices in another manufacturers CU as it wasn't connected to the bus bar.
