I have emailed electrical safety first regarding the BPG4 update : i have just received the reply

Hi,



It should be published in the next couple of weeks – it is in artwork and out for comment with the signatories.

Bets in on what code for Type A RCDs (I'm guessing C3 for now at worst, maybe C2 if fault protection by RCD), and AFDDs where they are mandated (likely C3 for now too I would expect)

Type A RCD = C3 I recon, even for fault protection.

AFDD, C3 but not so sure about that one.

You must mean type AC rcds? It should be C2 unless purely resistive loads present, but BPG4 have always been easy coders i think so most likely a C3 same with Arc Fault Detection Device in high risk residential building

I still think C3, as there would have to have at least 2 faults present for there to be danger: enough DC leakage to blind the RCD, and an earth fault. I'll bet codebreakers will have it as a C2 though.

Wonder if they'll mention lack of an SPD for first time.

It's in the current issue. Note only, or c3 where medical equipment is installed
