Can anyone offer experience on the application of Table 54.7 for Main Earth size on non PME supplies for supplies that have parallel incoming cables.
For example, 2 x 185mm2 PCV/SWA installed in separate ducts.
Thanks
I am looking at table 54.7 it does not appear to make any recommendations with respect to the application of parallel incoming cables, this is why I am asking experience in the application of this table with respect to parallel incoming cables.
I appreciate at the design stage these may be sized by calculation by the designer.
