We use load to size OCPD and wire size is done according to OCPD and distance due to voltage drop. No requirement to oversize for future although not a bad idea.jar546 said:So we don't know the load to determine wire size? Does the mfg spec MOP to match wire size or no because they can add more 5k heating elements? Even so, that still changes EG size if you up sized from 10 to 6
MOP is to account for inrush startup current. Compared to FLA rating.
