3 Phase-1 Phase Distribution Board RCD Test Adaptor - 10A to 50A

3 Phase-1 Phase Distribution Board RCD Test Adaptor - 10A to 50AOverview This simple 10A50A 3 phase adaptor is designed to support a wide range of electrical testing applications. It bonds L1, L2 and L3 together to allow energisation from a single phase supply, enabling RCD trip time testing from active to protective earth using a compatible portable appliance tester (PAT) or RCD tester. This makes the adaptor suitable for the testing of single phase RCD protected outlets on portable three phase worksite

Overview

This simple 10A–50A 3-phase adaptor is designed to support a wide range of electrical testing applications. It bonds L1, L2 and L3 together to allow energisation from a single-phase supply, enabling RCD trip time testing from active to protective earth using a compatible portable appliance tester (PAT) or RCD tester.

This makes the adaptor suitable for the testing of single-phase RCD-protected outlets on portable three-phase worksite distribution boards using a single-phase test supply.

In addition, the adaptor enables earth continuity and insulation resistance testing on 3-phase appliances and extension leads when used with a suitable appliance tester.

Note: This device is not capable of applying power to 3-phase appliances or converting single phase supply to 3-phase.

Applications

• Can be used with an RCD tester with isolation* (or a suitable portable appliance tester) to perform RCD tests on single phase outlets on 3-phase distribution boards.
• Allows testing of earth continuity and insulation resistance of 3-phase equipment and extension leads
• In conjunction with an RCD test adaptor (sold separately) the device enables functional verification of RCD operation on portable three-phase distribution boards without energising from the fixed installation.**

*Isolation transformer sold separately

**This adaptor does not provide a three-phase supply and should not be used where AS/NZS 3760 requires testing with a three-phase supply connected (Clause H.3.2).
