Went back it a house after they upgraded shower to a 9.8kw, pulling 40a constant.
We had wired it with 10sq and 40a RCBO.
10sq Neutral cable looping from neutral bar to RCDs and on to shower RCBO melted at neutral bar.
That's fair enough, must have been pulling a fair whack through it.
So I put in a new 10sq neutral going straight from neutral bar to shower RCBO.
They say the smell is back again.
I think the installation is pulling way over 63amps, when shower, cooker, dryer etc is on.
It's fed through a 100a double pole isolator, should I swap this out for a 63 amp MCB to cover my arse
