Am I correct in assuming that both ends of a ring main should be supplied from the same MCB. Logic tells me that this has to be so.
Am I also correct in assuming that an MCB should feed one and only one ring main ??
The installation is further complicated in that night storage heaters could have been supplied at one point. That being the case what would a blue MCB (16A) have been used for.
