I have 7 betapack 3s, 5 in a rack and 2 either side of the stage.
On the 5th pack in the rack, I am getting occasional but persistent tripping of the mains RBCO.
This is an old install, but recently the 4th and 5th packs have had their own 32amp supply fitted as they were previously fed from 13amp plugs on the stage ring-main.
The 4th pack does not trip, the individual channel MCBs in the 5th pack do not trip, and swapping the feeds between the packs, the issue remains on the 5th pack.
The show starts next week - any suggestions what is at fault? Thanks in advance.
