Increasingly, I am seeing a requirement for Type B RCDs in industrial applications, particularly where servo drives are used.
The preference is Type B RCBOs however, these are quite rare and not all manufacturers make them.
Aside from the high cost and short supply due to demand from EV and PV applications, how do others address this situation?
If the earthing is adequate, cables to the motors are run in trays and there is additional bonding to the motor housing, is there really a need for an RCD?
