A St. George electrical contractor offering installation, troubleshooting and repair for both residential and commercial customers.
Background
Wire is rated for a temperature, not simply for an amperage. The ampacity printed in the code tables assumes an ambient of 30 degrees Celsius, and it must be corrected downward as the surrounding air gets hotter. This matters more in southern Utah than almost anywhere else in the country, because an unconditioned attic here reaches temperatures far above that baseline in summer, and a circuit routed through it carries meaningfully less current safely than the same conductor in a basement. It is the reason a conductor that is perfectly legal in one part of a house can be undersized in another, and the reason attic-run circuits deserve a second look during any addition.

Frequently asked questions
Does heat change how much a wire can carry?
Yes. Conductor ampacity is rated at an ambient of 30 degrees Celsius and must be derated as temperature rises. An unconditioned attic in southern Utah runs far hotter than that, so a circuit run through it safely carries less current than the same wire elsewhere in the house.
