RCD Test - Main menu B

Please Note: Where ANY RCD testing, is to be carried out any circuit that is protected by an RCD in the main

switchboard (upstream), it‟s most likely to trip this upstream RCD. When performing RCD trip time or Ramp

current tests on any (portable) RCD devices, the RCD in the switchboard may trip faster. This is due to

increased upstream levels of leakage current from the additional circuits and devices connected to it. The

fixed RCD‟s can also have better connectivity, sensitivity and mechanical mechanisms.

To avoid tripping large areas in the work place monitored by the switchboard RCD it is suggested that an RCD

(Isolation Transformer) be used. These are designed specifically for the purposes of field RCD tripping.

DO NOT use these Transformers for any other purpose.

Ratings 240VAC in 240VAC Out @ 30VA Fuse protected Primary winding 500mA

To perform RCD tests the TnT+ supply lead needs to be plugged in to the RCD device to be trip tested. For

tripping switchboard mounted (Fixed) RCDs Plug TnT+ into GPO marked RCD protected or if known to be

protected circuit. (Diagram 2)

(Isolation Transformer Required) If testing portable RCD devices on power boards or extension leads plug

TnT+ into power board or lead (Isolation Transformer Required) Diagram 1
