The continuous parameter is used in system design with some system components that will operate for more than 3 hours continuously. Electrical components - like [[Wire and cable types|wires]] and [[Overcurrent protection|overcurrent protection devices]] generate heat during operation which can cause them to function below their rating if this happens for an extended period of time. It is therefore standard practice to oversize these components to ensure that they function properly.

The continuous duty safety parameter accounts for excess heat generated by components that operate for more than 3 hours continuously as it can reduce their performance and cause them to function below their current rating.

The continuous duty safety parameter accounts for excess heat generated by components that operate for more than 3 hours continuously as it can reduce their performance and cause them to function below their current rating. This value is used in the process of wire, overcurrent protection, and disconnect sizing and selection to ensure that these components are oversized in order to function properly under the conditions in which they will be used.

  • Continuous duty safety parameter = 1.25 (125%)
