	Rccbs are usually installed on individual circuits at the distribution board, or sometimes in the feeder to the whole board, depending upon the earthing system employed. __________________ "Did you get my e-mail?" - "The biggest problem in communication is the illusion that it has taken place" - George Bernard Shaw, 1856

	RCCBs are most usually AC-only devices, and will not work in a DC system. Some countries (including my own, unfortunately) insist on RCCBs being sensitive to pulsed DC, but even these will not work on steady DC. __________________ paulusgnome

	Do a Google search on 'dc earth fault protection' or 'dc ground fault protection' and you will find numerous websites of manufacturers and distributors of the sort of device that you are seeking. __________________ paulusgnome
