Remarks

Tolerance on conductor resistance is ± 5 % for all 300 volt 2/C cables and 600 volt 1/C cables.

The maximum recommended loading is 200 watts per metre for all 300 volt 2/C cables and 210 watts per metre for all 600 volt 1/C cables.

For pipe tracing, the maximum recommended watts per metre of cable may be reduced to the pipe to maintain or process temperature.

Minimum bend radius is 5 times nominal cable diameter.
