no i didnt think in that? i will try that wheni get back there...strange fault

the voltage drops to 212 with lightsand stays at that unless i turn more red phase mcbs on then it drops more...nothing else seems to be affected at all?

all connections checked and fine worked backwards only part not yet checked is tails from isolator to buss bar! unable to shut down at momemnt

measuring between L-E, L-N.. the other 2 phase dont change?

the supply is a 70mm swa via bus bar to isolator then isolator to db

i have been trying to find a fault on a 3 phase db! with all mcbs off red phase gives 236v, yellow 240v, blue 241v, when the lighting mcb is switched on and the lights switched on the red phase loses voltage to 212v and then when i turn more red phase circuits on it loses more voltage? yellow...
