Electrical testing will involve the following:
(i) Earth bond continuity tests
(ii) Insulation resistance testing
(iii) Functional checks
(i) Earth Bond continuity Test (Class 1 equipment only):
The resistance should not exceed (0.1+R) Ohms (where R is the resistance of the lead)
Either of the following tests may be performed:
A continuity measurement with a short-circuit test current within the range 20mA to 200mA
or
A continuity measurement with a test current not less than 1.5 times the rating of the fuse and no greater than 25A for a period of between 5 and 20 seconds.
(ii) Insulation Resistance Test:
The applied test voltage should be approximately 500 Vdc
Class 1 Heating equipment => 3kW 0.3M Ohms
Class 1 All other equipment 1M Ohms
Class 2 Equipment 2M Ohms
Class 3 Equipment 250k Ohms
(iii) Functional Tests:
The appliance should be checked for correct operation
