The Seaward Powercheck 1557 PAT/Installation Tester Checker is a powerful checkbox that can be used to verify the performance of any PAT tester or installation tester. It conforms to regulations including BS7671, EN61577 and the IET Code of Practice.
It is capable of checking numerous testing functions found on safety testers such as earth bond continuity, insulation resistance, RCD (trip time), RCD (trip current), PE conductor current, loop impedance, touch current and flash testing. The briefcase-style design means the checker will be protected in challenging environments.
