I recommend that you check with the receptacle vendors and your test laboratory for their requirements on this receptacle. The receptacle vendors will rate their products for use in a 60 degree ambient. The terminals will easily exceed this temperature at full load, but the receptacles have been designed to handle the heat. You might just find that 60 degrees is the limit for the ambient and that the receptacle is allowed to have a temperature rise above the maximum ambient temperature.

Rating PM >60 C Greetings Regulatory Professionals, I have a need to source for a single-outlet, NEMA 5-15R receptacle that has a temperature rating of at least 70 deg. C. I have reviewed the temperature ratings for several manufacturers of a single-outlet receptacle of this type and cannot find any with a temperature rating above 60 deg. C. I have also reviewed UL 498 and can find no prohibition for such a rating. For background information, the application is an electrical appliance which will have a wall-wart, Class II transformer plugged into this receptacle inside the unit. Actual power conducted through the receptacle is very small (less than 1 A), but the appliance is rated for a maximum 40 deg C ambient and the other power-consuming components inside the appliance combine to yield a temperature of approx. 64 deg C on the outlet under maximum use conditions when the unit is located in a 40 C ambient. Therefore, the agency testing the unit will not accept a receptacle rated for maximum 60 deg C. Can any of you direct me to a source for such a receptacle rated at least 70 deg C? Thanks in advance for any information you may be able to share. Good day, Richard I.
