Are there any situations where you are allowed to downsize the neutral in residential, commercial, or industrial jobs? To prevent heating problems, this conductor is run with the ungrounded (phase) conductors as required by 250.24 (c) (1). Web true, most terminations simply aren't rated to carry 90°c, but remember that when you adjust the ampacity of a conductor due to ambient temperature or conductor bundling, you use the 90°c column to begin the calculation (assuming you are using a conductor 90°c insulation rating). Web circuit conductors must be sized according to the 60°c column of table 310.15 (b) (16) for equipment rated 100 amperes and less, unless marked otherwise, and equipment rated over 100 amperes must be sized to the 75°c column of table 310.15 (b) (16) [110.14 (c)].
