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 parameter accounts for excess heat generated by appliances 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 [[Wire and cable types|wires]] and [[Overcurrent protection|overcurrent protection devices]] sizing to ensure that these components are oversized in order to function properly under the conditions in which they will be used.

The continuous parameter accounts for excess heat generated by appliances 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 wires and overcurrent protection devices sizing to ensure that these components are oversized in order to function properly under the conditions in which they will be used.

  • Continous duty safety parameter = 1.25 (125%)
