Continuous load and conductor bundling rules are a common point of confusion in the field, especially when both NEC evaluations apply to the same branch circuit. Many electricians understand the 125% continuous-load requirement. Many also understand conductor ampacity adjustment for more than three current-carrying conductors. But confusion starts when both conditions exist at the same … Read more
A common point of confusion in the field is how continuous-load rules affect garage heaters, workshop heaters, and other fixed electric space-heating equipment. Most of the confusion starts when people blend together: as though they are all the same thing. They are not.
