Before you use this
WireRef is a planning and estimation aid — not professional engineering advice, and not a substitute for the current code books or a licensed professional. Every result must be verified against the current NEC, ABYC, and other applicable standards and your AHJ before any installation. The app is provided “as is,” without warranty of any kind, and you use it entirely at your own risk. Not affiliated with or endorsed by NFPA, ABYC, NMEA, or IEC.
