APPENDIX C
If an external Residual Current Device (RCD) is used it should be of Type A/AC with a tripping
current of 30mA or higher.
Use of RCDs
Residual Current Devices (RCDs): An RCD dedicated for an Inverter Energy System (IES) may
be used to meet the mechanical cable protection requirements of AS/NZS3000 for the cable
from the switchboard to the IES. If an RCD is installed the engineer must:
1. Disconnect all live conductors (including both active and neutral conductors) and
2. Be of the type specified in the inverter manufacturer’s instructions or as labelled on the in-
verter.
We recommend the use of an RCD on all circuits and sub-circuits connected to the Sunsynk
Inverter. Below is the specifications for a Residual Current Breaker with Overcurrent Protection
(RCBO)
