Note: The conversion factors are only used for cables of one layer grouping arrangement. These are not valid when the cables are installed one upon anoter with contact, or when the given sprees between cable toughs or cable trays are not followed. In those cases the conversion factor can be reduced.
In parallel current circuits each group of three conductors of the parallel circuit is regarded as single circuit.
