But would that actually be YOUR concern? ANY diy joe can go and do something stupid after you. I`ve had someone go into one of my jobs; and swap an rcbo for an mcb, `cos he "needed" an rcbo on another job!!!!!Nothing I can do, other than move his chewing equipment nearer his rectum, but that doesn`t help the customer. I know it sounds hard, but coertify your work properly, and walk away.
TOTALLY AGREE,
as for 17th, its still not a requirement for 30mA protection, if you provide other protection,
way back when, and still today believe it or not,
500mA is adequate protection for a TT system,
tho, TBH I always use a 100mA as a main switch on TT.
too many people are reading the regs as law,
they are only a guide, (jez Im fed up saying that(watch my signature))
i personally have had lots of digs from a 30mA without it tripping, P-N, treats u as a kettle element, only detects leakage to earth so on a 1667 resistance would be negilable, but the overcurrent wopuld be instantly cut off,
choose your MCB/RCBO wisely.
