Do you apply demand factors on recpt. load if the load is continous.

A 20-amp circuit with one 60-watt lamp plugged into it that stays on 24-hours per day seven days per week would not be considered a continuous load. Anything that is controlled by a thermostat and plugs in, such as a refrigerator, or microwave, is not considered a continuous load. The list of equipment that is cord-and-plug connected and a continuous load is fairly short. Most cord and plug connected equipment is designed to be portable and easily exchanged. If you do have permanent equipment that is a continuous load, perhaps some thought should be given to hard-wiring the equipment, rather than plugging it in.
I agree. But that does not change my answer to the original question. The notion of continuous loads does not enter into the calculation of loads associated with general purpose receptacles.augie47 said:. . . that 60 watt lamp, once it is on for 3 hours or more is a continuous load. (per NEC)

Continuous Load. A load where the maximum current is expected to continue for 3 hours or more.
