Where in the nec can I find the 125%
2023 NEC
This is what I call making the 'loop' branch circuits, feeders, and services. There are several other continuous loads found in your Code book.
For Branch Circuits 210.19 Conductors -
Minimum Ampacity and Size (A) (1) General ......125%
For Branch circuits 210.20 (A)
Overcurrent Protection.... Branch Circuits Continuous and Noncontinuous Loads
For Feeder Conductors Sizing
Minimum Rating and Size 215.2(A)(1)
For Feeder Overcurrent Protection 215.3..... 125 %
For Service Conductors
Minimum Size and Ampacity 230.42 (A) (1)
For service Overcurrent Protection
Where Required 230.90 (A) and
Exception No.2
However, you will find the 125% factor for several other various types of other
continuous loads, so you must refer to them when it's necessary and not just in the references that I have listed above.
Hope this is helpful.
Thanks for reading.
