The maximum permissible continuous current rating of the conductor bar depends on the duty factor of the

cranes and the maximum ambient  temperature Ta. It can be established using the following formula:

Conductor	Ampacity	Resistance R (DC)*	Reactance 60 HZ 30*	Independence z (60 HZ)*	Spacing in. (mm)
Steel	40A	2382	382	2412	0.75 (19.1)
Copper	120A	245	38	248	0.75 (19.1)

*Micro-Ohms Per Foot

The appropriate conductor bar can be chosen only when all the relevant factors are known.  Please refer to the Data Sheet on Pgs. 6-7, and to Appendices

I through  IV at the back of this catalog. Also, please consult Conductix-Wampfler Sales if you have any questions about the suitability of this product to your application.
