🔍 Key Concepts

• Rated load of an electric motor • Meaning of ambient temperature in machinery spaces • How manufacturers specify allowable temperature rise for insulation and safe operation

💭 Think About

• Which choice mentions a condition that the motor is DESIGNED and SPECIFIED to operate at continuously, not just temporarily or at overload? • Does temperature rise refer to a change from ambient conditions or an absolute temperature number? • Which options describe something that a manufacturer could clearly put on a nameplate as a standard performance characteristic?

✅ Before You Answer

• Identify which options talk about rated load versus overload or weather-related changes • Check which option correctly connects temperature rise with standard ambient temperature, not varying outside weather • Eliminate any choices that describe conditions that are temporary, unusual, or not something normally found on a motor nameplate rating
