Ensure proper sizing and application in accordance with the National Electrical Code (NEC) guidelines. For motor circuits, size at 300% to 400% according to NEC motor ampacity tables 430.247, 430.250, and 430.6(A)(1).
Note: One-time fuses do not have any appreciable degree of time delay and should not be specified in circuits where large transients or motor overloads occur. For such applications, consider using time-delay fuses.
