Hello,
I was looking at the consumer unit at my parents house. They recently had a kitchen refurb and some electrical work done including a new consumer unit I think its an MK 17 edition type.
It has a TT earth setup and the tails go from this 63Amps rcd into the consumer unit, the main switch says 100A
The electrics work without issue but I was wondering if the RCD should be upgraded maybe at leat to 80Amp which is what the the RCD's in the board are.
Does it still need the extra RCD as the board has them built in or did I read it was a requirement for TT earth setups?
Cheers
