RCDs do not protect against circuit overload like a circuit breaker, they only trip under earth leakage faults. Thats why its important that electricians who specialise in such maintenance are engaged for Planned Preventative Maintenance (PPM). Therefore in a commercial building an RCD will be neededwhere BS 7671 requires it. Also, the added feature for sprinkler protection to commercial classifications does not provide appropriate minimum or comparative levels of protection to that of LPC rules and BS EN 12845. Do Commercial premises need RCD protection? RCD protection to the sub circuits is required in the current 18th edition of BS 7671 IEE Regulation.
