What Steps are in a PAT Test?

The PAT Test "In Depth"

The test is split into 2 parts:

  • First, the "formal visual inspection"
  • And secondly, the "electrical tests"


The Visual Inspection

  • Visual inspection of appliance to determine damaged or faulty equipment
  • Visual inspection of flex and plug. Replace plug if appriopriate
  • Open and inspect plug and check for correct fuse.
  • Check wiring, tighten connections - rewire if necessary.


The Electrical Tests

Carry out the electrical tests as follows:

  • Earth continuity test (on class 1 equipment)
  • Insulation resistance test
  • Protective Conductor test
  • Functional Test


Label appropriately with Pass or Fail labels

Record results assigning each appliance with its own ID number for future reference.

Notify/bring to the attention of the duty holder of any of the above points if appropriate.


NOTE: For integrated or hard-wired appliances, it might only be possible to carry out a visual inspection.
