- Worth noticing
- The wire-sizing interface includes a rooftop raceway temperature adjustment and cites NEC 310.15(B)(2).
Field notes
The wire-size form exposes choices for copper or aluminum, supply configuration, breaker poles, insulation, raceway, ambient temperature, and circuit conditions. Other sections include motor-protection options and conduit-fill notes, including the cited allowance for nipples 24 inches or shorter. Copy controls are visible for several workflows, while the page’s prototype label leaves the reliability and currency of its calculations unverified.
