A 3‑Phase RCD Tester (20 A) is an accessory designed to work with portable appliance testers (PATs) to enable residual current device (RCD) testing on three‑phase equipment rated up to 20 A. It supplies a controlled leakage current across all three phases and neutral so that the PAT can measure the RCD’s trip time and trip current under realistic load conditions. This accessory is used in electrical safety inspections to ensure that three‑phase RCDs operate correctly and comply with relevant safety standards when installed on industrial and commercial equipment.
