6. Installation
• The RCD should form part of a 30A ring main or
terminate a spur off a 30A ring main. The cable
connecting the supply to the RCD should be either:
2x 2.5mm² for the ring main or 1x 2.5mm for the spur.
• Fit the appropriate BS1362 fuse to suit the load
appliance to be connected.
• The cable connecting the load appliance should be rated
according to the fuse fitted to the connection unit.
• Make sure to tighten all screw terminals onto
exposed wires.
• Ensure that there is both sufficient length of the supply
cable tails(s) to enable easy wiring.
6.1 Ensure the mains supply is switched off and the circuit
supply fuses are removed or the circuit breaker turned off.
6.2 Connect the incoming 230V 50Hz supply and outgoing
load cables to the relevant terminals ensuring correct
polarity is observed and that all bare conductors are
sleeved (see section 7. Connection Diagrams).
6.3 A front cable exit cut-out is provided on the RCD10WPVN
and RCD11WPVN units. The RCD10WPVN has a pre-
installed removable blanking plate and the RCD11WPVN
front cable exit needs to be cut-out manually.
6.4 If the front exiting cable cut-out is required:-
1. Cut-out the front cable exit or remove the blanking
plate (you can discard the blanking plate at this stage).
2. Remove the cable grip and clamp screw from the
accessory pack.
