Did an RCD test on a new consumer unit, but got a fail on 1 times, but passed on 1/2times & 5 times.
Thought it may just be the rcd so i checked my instrument on the second rcd, but was perfect.
So then i swapped the rcd over & tested again but same happend again failed on 1 times but passed on 5 times.
All mcbs are switched off, & i tested at supply side of the rcd.
Any ideas??
