Plym PAT Testing

General information

Pat Testing usually consists of four steps:

Visual inspection - Hazards such as the wrong kind of plug, damaged or incorrectly wired plugs, the wrong fuse ratings, damage to the appliance casing, lumps, cracks or burns to the mains supply leads, unsafe cable joints and loose connections are all checked and either passed, repaired or failed by the engineer.

Earth bond test - This test ensures that the appliance has a suitable earth conductor connected and that there are no breaks or other kind of damage to the earth cable.

Insulation test - An insulation test is carried out to ensure that the correct insulation is in place and is working to the manufacturers specifications.

Polarity check - When testing IEC cables and extension leads, a polarity test is carried out to ensure that the cable is wired correctly to the plugs and/or sockets.
