A 25-horsepower, three-phase induction motor has a nameplate rating of 32 amperes. The nameplate also shows a temperature rise of 30 degrees C. What is the overload size for this motor in amperes

Respuesta :

Lanuel

Based on the calculation, the overload size for this inductor motor in Amperes is equal to 40 amperes.

Given the following data:

  • Power rating = 25-horsepower.
  • Nameplate rating = 32 amperes.
  • Temperature rise = 30°C.

How to determine overload size for this motor?

According to Section 430.32(A)(1) of the National Electrical Code (NEC), the overload size is 125% (1.25) of the full-load current rating of a polyphase (three-phase) inductor motor.

Therefore, the overload size for this inductor motor in Amperes is given by:

Overload size = 32 × 1.25

Overload size = 40 amperes.
