[QUOTE="jdiddy, post: 504316, member: 33363"] I have a new two month old 18th edition consumer unit with RCBO protection for each circuit and a simple main switch. The house has a TT supply but has been converted in the past by the DNO to be PME. I am having an air source heat pump installed (panasonic Aquerea) and yesterday come back to two 32 amp MCB's therefore offering no RCD protection to the outside heat pump isolators. Does this sound ok to you or is this a violation of BS 7671 411.3.3 ? I expected to have installed 100mA RCBO's and whist the actual device may include a built in RCD the cable would not be protected right? [/QUOTE]
