Seaward PowerCheck 1557 PAT And Installation Verification Unit

 

The Seaward PowerCheck 1557 is a comprehensive PAT and installation verification checkbox. The Seaward PowerCheck 1557 carries out ongoing performance checks to ensure accurate measurement between calibration intervals. The Seaward PowerCheck 1557 fully tests Earth Continuity, Insulation Resistance, RCD Trip Time, RCD Trip Current, Loop, PE Conductor Current, Touch Current and Flash tests.

The Seaward PowerCheck 1557 can be used on earth continuity or earth bond testers up to 25A and also verifies loop impedance or RCD testers on RCD protected circuits - without tripping the RCD. The Seaward PowerCheck 1557 tests to BS 7671, BS EN 61557, IET Onsite Guide and IEE Code of Practice. The Seaward PowerCheck 1557 has full instrument verification against all relevant standards and confirms performance between verifications (this is information required by NICEIC, ELECSA, NAPIT and others).
