Be sure to read the following precautions when you place an order.
* Length in "m" is included in our part numbers. Always specify quantity as number of units, not as meters.
*2 All unit prices above are per meter.
Unit Price Calculation Method [Formula: Last digits of part number (m) x unit price per meter above]
*4 Check the indications for number of cores, pair number, core / pair number, and pair number / core when ordering (check the Specification Table for number of wire cores). 1P (1 PS) is "x 2-core".

*1 Please note that when the indicated Core / Pair is 1P (1PS), the number of wire cores will be "x 2-core".
*2 The size conversion is for reference only. Refer to the comparison table on >>Click here for details.
*3 The value of allowable current is to be used only as a reference value and is not guaranteed.

Current Reduction Factor

Ambient Temperature (°C)	30	40	50	60	70	80
Current Reduction Factor	1.00	0.91	0.82	0.71	0.58	0.41

Allowable current value indicates the calculated value of 1 cable laid aboveground in ambient temperature of 30°C, and is not a guaranteed value.
If the ambient temperature is 30 °C or above, the above current reduction factor is multiplied by the allowable current.
(Example)Allowable current at AWG20 2-core when the ambient temperature is 40°C
7.3 × 0.91 = 6.643 (A)
