Ampacity: Chosing Cable When The Heat Is On

Featured Product from Lapp Tannehill

 Most power cable is sized according to its ampacity, a fact that underscores the importance of first considering amperage needs when selecting portable power cable. By doing so, you’ll avoid serious safety hazards, equipment damage and production downtime caused by overcurrent — i.e., too much current flowing through a conductor — which is a significant threat to under-amped cable. Excessive current can cause overheating, insulation damage and fire/ shock hazards that, in turn, can harm equipment through heat buildup and produce cable faults that lead to lost productivity.
