■Permissible current of wire
The following table shows permissible currents of wire based on Table 28.1 of UL 508A and Table 40.3 of UL 508C.
The permissible current values listed in this table are for when the number of wires bundled is three or less. When the number
of wires bundled is four to six, the permissible current values are 80 % of the values in the table.
