Sorry to hijack the thread, we have an 8.5kw shower using 32A/240v at the MCB via 6mm cable. We had an electrician look into this as the RCD kept tripping when we used it on high (2 red dots) although it's fine on low (1 red dot). The electrician said the 32A was the problem and we needed a 40A but he couldn't fit one because of the 6mm cable, he said we needed 10mm.
What I'm getting from this thread is it's OK to put a 40A on to 6mm?
We have a spare 40A/240v in the MCB, I think it's the old cooker one, is it OK to just swap them over after switching the big red switch off?
