SLIDE 1 (HOOK / COVER)

⚡ NEC Quick Hit: Outdoor Deicing & Snow-Melting (Part 1 - Article 426) ⚡

Fixed snow-melting scopes, mandatory listing rules, and the total ban on reconditioned equipment—welcome to Article 426! How does the National Electrical Code regulate outdoor heating systems? Let's break down the fundamentals! 👇

SLIDE 2 (SCOPE & LISTING REQUIREMENTS)

What Article 426 Covers:

• System Scope: Covers fixed outdoor electric deicing and snow-melting equipment, including resistance heating elements, impedance heating systems, and skin-effect heating systems.

• Listing Mandate: Fixed outdoor deicing and snow-melting equipment—including conductive pavement heating systems—must be listed.

SLIDE 3 (RECONDITIONED BAN & CONTINUOUS LOADS)

Strict Code Prohibitions:

• No Reconditioned Equipment: Reconditioned equipment is strictly prohibited from being installed for outdoor deicing and snow-melting applications.

• Continuous Load Sizing: Fixed outdoor electric deicing and snow-melting equipment is officially considered a continuous load for sizing branch circuits, feeders, service conductors, and OCPDs.

SLIDE 4 (WRAP-UP) 💡 Apprentice Pro-Tip: 

Never attempt to install reconditioned snow-melting cables or equipment—Article 426 completely bans reconditioned components for outdoor deicing systems!
