Demand Factor Dilemma

Demand Factor Dilemma

Demand Factor Dilemma

(OP)
For a large existing hotel two new circuits will be added to each guest room to eliminate nuisance CB trips caused by too many coffee pots and hairdryers. These new circuits will feed only one receptacle each per room (one for a hairdryer & one for a coffee pot). New panels & transformers will be added to accommodate only these new circuits. Of course, overall, only a fraction of the coffee pots & hairdryers would operate simultaneously, at any given time (short of a vast conspiracy conducted by the quests). Using connected load data to size distribution equipment and feeders results in oversizing, simply to suit the NEC. Is there anything such as a demand factor that could be applied to the panel, transformer, and feeder sizes that would be code-compliant?

RE: Demand Factor Dilemma

I don't think that any IEC compliant solution would also be NEC compliant.  Or that this kind of thing is addressed at all in any IEC standards.
