5-1 Selection of wire
5-1-1 Example of wires by unit
Selected wires must be able to tolerate rated current of the unit’s terminal to which the wire is
connected.
How to calculate tolerable current of an insulated wire or cable is shown in “Tolerable current of electric
cable” (1) of Japanese Cable Makers’ Association Standard (JCS)-168-E (1995), its electric equipment
technical standards or JEAC regulates tolerable current, etc. wire.
When exporting wires, select them according to the related standards of the country or area to export.
In the UL standards, certification conditions are to use wires of 60
o
C and 75
o
C product. (UL508C)
Wire’s tolerable current is different depending on conditions such as its material, structure, ambient
temperature, etc. Check the tolerable current described in the specification of the wire to use.
Example of wire selections according to each standard is as follows.
