Rcbos In Series. The current hager single pole rcbos fit in place of ge but obviously will not be type tested with ge boards so is not an approved replacement. I presume that the current crop of ge mcb s fit the older boards.
Yes and i have looked it up. Rcbo residual current circuit breakers with overcurrent protection devices are a combination of an rcd residual current device and mcb miniature circuit breaker in one. I ve done my cable calculations and volt drop ect and sized the cable at 4mm 1 5mm swa because of the long run.
Current flowing where it shouldn t switching the circuit off where there is an earth fault current.

The current mcb s are series e i know ideally you re not meant to mix and match but i d rather have protection than not. I m going to protect the sub main with a 25a rcbo my question is will i be fine with sub c u not containing an rcd main switch as this will be in series i didn t want any nusance tripping. Ds203nc rcbos are the ideal solution for new installations ensuring space saving in switchboards as well as in retrofitting of existing plants by adding earth fault current protection in installations where it wasn t foreseen without any impact on the overall dimensions of the system and on the placing of the existing devices.
