Not pedantic, accurate. It would be quite simple to state a 32 amp mcb following a 30 mA RCD, or something of that ilk. You will have some poor devil going round all the sheds looking for a 32 amp RCD saying "It must be right Fire said so." Please try to be accurate, we all make mistakes and I make plenty. The clients on this site are looking for help and they need correct information not "I used the simplified method", it doesn't mean anything to them. Kind regards
