About 20Meters of 25mm meter tails are routed though the floor boards feeding a sub main.
To protect the tails under the floor i was going to fit a Mini Metal Unit with RCD protection Fused at 50A at the mains position, Just wanted to check to ensure it’s a 30ma ‘S Type’ RCD i need? As the c.u being fitted at the other end is a dual rcd board and want to minimise the tails rcd tripping.
(unfortunately cables are already in place so running the feed in swa for example isn’t possible)
Thanks.
