4.4 Variable RCD
A Variable RCD (Residual Current Device) Circuit Breaker is provided as part of
the AC output protection system. It allows for the adjustment of the sensitivity
and time delay before the Variable RCD trips.
The Variable RCD is a vital safety device providing protection
from potentially fatal electrocution. It is factory adjusted for
standard use and should not be adjusted without consulting
the manufacturer.
A Variable RCD is adjusted when one or more additional RCDs are used further
down the power distribution chain. Contact the manufacturer for further
information before attempting to make adjustments to the Variable RCD.
The Variable RCD is factory set for 30 mA sensitivity with zero delay.
