Hi,

I have been made aware of a 1-phase circuit run from a 3-phase board, in SWA to a new CU powering a large extension room. Apparently the 1-phase has been spurred off directly from the supply with no isolator or protection. i havent seen the install yet, but can anyone recommend a suitable isolator/protection combo (i.e. switch/fuse or similar?) ideally 100A.

does this look ok? unsure of SWA rating yet, will adjust fuse as reqd

100A fused switch, Moulded White control gear fused switch up to 100A [800KMF] : Sparks Direct, Lighting and Electrical Wholesaler

tks
