Description

The Seaward Powercheck 1557 PAT/Installation Tester Checker is an extremely useful checkbox which can be used with any PAT tester or electrical installation tester. It conforms to all pertinent regulations including BS7671, EN 61577 and the IEE Code of Practice. It can perform numerous tests to verify the performance of testers and is also compliant with NICEIC and IET standards.

Colour-coded test functions make the Seaward Powercheck 1557 an easy instrument to operate so it is straightforward to verify PAT tests such as full earth continuity, insulation resistance, RCD trip time, RCD trip current, loop, PE conductor current, touch current and flash test. The checker has sturdy briefcase-style housing which enables it to stand up to poor weather conditions and other day-to-day challenges.
