• The current correction coefficient is determined using the following formula:
(Max. permissible temp. – ambient temp.) ÷ 30
The current correction coefficient is determined according to the cable. Check the specifi-

cation of the cable used.
• The current reduction coefficient is provided for the
case where the cable (-conductor cable in the case of
example), is housed in plastic race/sheath, plastic tube,
metal race/sheath, metal tube or flexible conduit.
Caution Because the neutral conductor is not counted as a wire, the
current reduction coefficient for "3 or less" is applied as indi-
cated by ( ) in the table right.
• Recommended eco-cable
Wire category: -conductor polyethylene-insulated power cable with heat-resistant
polyethylene sheath (Standard: EM JIS C 605)

as operating ambient temperature and current.
• Current reduction coefficient, fundamental permissible current, etc., stated on this page
are subject to change due to e.g. standard revision. Consult cable manufacturers for
