16.15 Loading
16.15.1 A supporting device shall support a load equal to four times the total mass to be supported under
intended operating conditions for 1 h. The load shall be applied in the direction of actual loading
conditions.
16.15.2 Where more than one support is provided, the load shall be distributed as follows:
(a) where the parts supported are no more than 11.3 kg (25 lb), the full load shall be applied to
each support; or
(b) where the parts supported are more than 11.3 kg (25 lb), the distribution of the load shall
be similar to that encountered in the field.
16.15.3 There shall be no deflection or deformation either during or after loading that reduces electrical
spacings or compromises safety.
