Where temporary connections to the main circuit are used, they shall be such that there is no
significant difference in heat conducted away from, or conveyed to, the switchgear and
controlgear during the test compared to the connections intended to be used for service. The
temperature rise at the terminals of the main circuit, and at the temporary connections at a
distance of 1 m from the terminals, shall be measured. The difference in temperature rise
shall not exceed 5 K. The type and sizes of the temporary connections shall be recorded in
the test report.
