supplementary bonding and rcd protection

paulthemagpie · Feb 13, 2015

Hi,

a recent PIR has picked up no RCD protection and no supplemantry bonding to pipe work.

Am i correct in saying if all circuits to bathroom are protected by RCD then supplementary bonding is not required?

couldn't you have put your last 3 questions in one thread? seen as though its all the same job?

Getting out of hand now, why you taking on jobs not knowing what what's ?

Not necessarily, see 701.415.2 iv, v, vi

Not quite true, it depends what type of installation you are talking about, SB is still required in a lot of cases.

If you are talking about domestic bathrooms, then all of these conditions need to be met to omit SB,

1) the final circuits meet the requirements for ADS
2) all final circuits in the location have additional protection by means of an RCD 30mA
3) all extraneous conductive parts of the location are effectively connected to the protective equipotential bonding (main protective bonds) to the MET
