Hi all
came upon a 3 phase + N supply into a domestic property with only one of the phases being used to feed the c/u.
On the cert do i put down 3 phase or single phase
thanks
john
 
Never assume anything, if no meters are installed for other phases then it is a single phase supply. Although I would put it down as a 4 wire 3 phase system, as long as that is what the main incoming cable is.n

That's the way I would look at it too.
 
Only 1 x single phase meter fitted so I'll call it 4 wire 3 phase T-N-S supply but treat it on the cert as a single phase supply.
thanks Dillb and ruston
