Regarding local supplementary equipotential bonding in the bathroom; the mirror & ceiling lights are connected into the supplementary bonding loop running from the water/CH pipe work, through the mirror light up to the ceiling light & then looped over in the general direction of the ceiling fan. The fan is fed from a separate spur in the same loft mounted junction box that feeds the ceiling & mirror light spur.
The lights are class 1 & no problem as they have E feeds & terminals but the fan, fed from a double pole, fused switch on the wall outside the bathroom, is class 2 & doesn’t have an earth terminal; although there is an earth tail insulated & tucked back which is connected back to the external fan switch! The regs. say both class 1 & 2 equipment circuits must be bonded but what am I supposed to connect the bonding cable to?
