Is there a presumption in the code that if the circuit is 240 volts, it is a "motor" circuit? If the circuit feeds wall outlets, then anything, not necessarily motors, can be plugged into those outlets. And, even if it is a motor, it's impossible to determine in advance what the FLA of those motors might be. How then can a 240v circuit that feeds wall receptacles be sized per Article 430.

If it is assumed that the FLA won't be in excess of the current rating of the outlet, and there are multiple outlets, does not the circumstances of my previous post then come into play. Or does the code allow, for example, 20 amp receptacles in circuits protected by 60 amp breakers?
