In all the service calculation examples I've seen, including Mike Holt's articles and videos, none ever applied 125% to continuous loads for purposes of calculating the service size. Fixed electric space heating, for example, is defined in article 424 as a continuous load, yet that is never taken into account when calculating service size. I generally use 220.80 optional method for sizing services.
I've done a lot of research to justify this practice, but have found very little that gets to the point. Can anyone explain why continuous loads don't matter in sizing services?
