Residual Current Device (RCD) - Models Outside
of North America
In some countries, an RCD is known as an Earth Leakage Trip,
Ground Fault Circuit Interrupter (GFCI), Appliance Leakage
Current Interrupter (ALCI) or Earth (Ground) Leakage Current
Breaker.
When locally allowed, an RCD must be installed. In some power
network earthing systems, an RCD may not be allowed.
The RCD must have the following specifications:
• Tripping current of 100mA (if not locally available/allowed,
use a 30mA trip current, preferably selective type with small
time delay set)
• Type B (components inside the machine which make use of
DC voltages and require this better performance RCD)
• Maximum of 2 machines installed on each RCD (for 30mA,
only 1 machine)
Some washer control circuits are supplied with a separating trans-
former. Therefore, the RCD may not detect faults in the control
circuits (but the fuse(s) on the separating transformer will).
Supply Protection Device
A supply protection device protects the machine and wiring
against short circuits. (Glow-wire) fuses or (automatic) circuit
breakers may be used as supply protection devices.
Protection must be the "slow" type, which means curve D for cir-
cuit breakers.
