Reference table for cable gauge and current| 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. |
