How do I determine amperage or current load capacity of a given size wire conductor or copper rod?
Current capacity is affected by many different factors, including how much heat is carried away from the conductor. This would be theoretically more limited if there is less air surrounding the conductor (lower pressure), but a curve showing this would have to be generated with a specifically controlled experiment in the actual customer’s application. The current capacity has no relation to the pressure or vacuum level. The only direct relation that the pressure or vacuum level has to an electrical characteristic is the voltage rating. However, we don’t have any data to develop a curve that shows that relationship. See weblink http://www.powerstream.com/Wire_Size.htm for more information on amperage load carrying capacities and AWG wire sizes and metric wire gauges. Please fax order and credit card info (NO emails with credit card info!) to +1 937 890 5165 or call +1 937 890 1100 x10 with card #, expiration date and CVD code on back of card. The shipping address must match credit card
