A252 Portable Appliance Tester INTRODUCTION
NOTES
All safety tests must be carried out with the supply switch of the tool or appliance in the ON position to
ensure that all 'live' parts are included when checking insulation.
Some specialised equipment with heavy duty motors etc. may employ contactor or relay start switching
techniques, therefore to apply a satisfactory insulation (flash) test through such devices the contacts must
be held closed by some, safe, manual means - the advice of the manufacturer must be sought on methods
to achieve this in the least hazardous manner.
Some 'trigger' operated equipment may require the switch to be temporarily held in the ON position with
insulating tape or string - under no circumstances should it be held in by hand,

EMEMBER TO RELEASE THE SUPPLY SWITCH WHEN TESTING IS COMPLETE
.
Multi - function tools and appliances must be fully tested with supply and function switches set for each
operating mode.
