About When is the highest current in photovoltaic panels

Throughout the Code, when dealing with currents, we see the phrase “125% of the continuous currents plus 100% of the noncontinuous currents” [e.g. 210.19(A)(1), 215.1(A)(1)]. This Code requirement is used when calculating the ampacity of conductors and to some extent in the rating of.

The NEC requirements for calculating conductor ampacities are designed to ensure that the conductors do not operate over 80% of their rating continuously or if there are significant conditions of use involved, the conductor size is determined by those conditions.
