Home equipment with a double field image are of Class II building. On this case, simply the Insulation Resistance check is carried out throughout PAT testing.
Home equipment with out the double field image are of Class I building and wish the Earth Continuity and the Insulation Resistance checks carried out throughout PAT testing. If the equipment is in a metallic enclosure, like an electric hearth or a washer, then it’s comparatively straightforward to clip the Earth Check result in a metallic level. These home equipment are labeled as Class I metallic.
Class I plastic home equipment are completely enclosed in plastic. It isn’t potential to hold out the earth Continuity check on these home equipment as there isn’t a Earth Level to clip onto. On this case, one must do exactly the Insulation Resistance check when PAT testing is carried out. You will need to make applicable notes as to why the earth Continuity check was not carried out.
Energy cords reminiscent of Pc IEC cables or mains extension leads want three checks carried out on them throughout PAT testing. These are the Earth Continuity, Insulation Resistance and the Polarity check. The latter check checks that the Stay and Impartial wires are appropriately linked.
Two core energy cords should not have an earth. They’re to be used on Class II tools. They can be inserted both method spherical and never polarity delicate. It’s usually solely vital to hold out an inspection on these.
