Sorry didn't give enough info on my previous thread. Looking for an 8 way (8 three pole mcb's) three phase dist board. Max height 600mm, Max width 410mm. Cheers.
Got a Ze of 0.6 ohm on a TN-S.
Circuit protected by a 250 amp mccb with an operating Zs of 0.073 ohms. Any ideas what I can do? Any advise much appreciated.
