A252 Portable Appliance Tester TEST PROCEDURES
V ISUAL I NSPECTION
Before applying the Earth Bonding and Insulation tests a thorough visual inspection of the appliance must
be carried out. This may well form the greater part - 75% or more - of any test routine.
C
ASING
Check for signs of undue wear, cracks or dents, missing components such as guards, covers or hand grips
etc.
Ensure that all screws and catches are present and secure.
Check for evidence of excessive dust and dirt build up in and around any ventilation slots, especially
carbon-brush dust which is highly conductive and could create a 'live' path around insulation barriers.
Also ensure that all movable guards operate smoothly.
S UPPLY Lead
Check for any signs of damage or fraying along the entire length, this should also include any extension
lead that may be regularly used with the appliance.
Ensure that any cable entry or connector is sound and secure.
