[QUOTE="Sidewinder, post: 372317, member: 9512"] GOOD FIND! I could not have recalled that, so, in fact that could be used to prevent the use of separate 1ph breakers or individual BS88 fuses for a balanced 3ph load, if the use of these could cause damage or danger. Considering the undetected loss of one phase on a running 3ph motor might not cause an issue, then this could be extrapolated to require linked breakers on ALL 3ph motors that come under BS7671...
