Reference table for cable gauge and current
Note : Instruments will be working condition if the reference table is complied.
 
Make sure the wire gauge are proper for the input and output of power supply ,especially CD , CF-A and CIF-A Series . If do so ,over-heated circumstances will be avoided. The table regarding to the gauge upon different temperature is as follows.

The impedance of wire is in direct ratio with its length, and depends inversely as diameter of wire. It affects output characteristics of CD-SERIES DC power supplies, CF-A SERIES and CIF-A SERIES AC power source directly. Therefore, voltage that measured from output terminal is not as same as the voltage on load. In general, potential difference can't be More than 0.5V.
Remark : To double or even trip the wire gauge when potential difference is above 0.5V.
