SLIDE 1 (HOOK / COVER)

⚡ NEC Quick Hit: Wiring Devices (Part 1 - Article 406) ⚡

Receptacle ratings, weather-resistant mandates, and strict wet-location rules—welcome to Article 406! How does the National Electrical Code regulate wiring devices? Let's break down the fundamentals! 👇

SLIDE 2 (SCOPE, LISTING & RECONDITIONED EQUIPMENT)

General Requirements:

• Article Scope: Covers the rating, type, and installation of wiring devices.

• Listing Mandate: All wiring devices must be listed.

• Reconditioned Ban: Reconditioned wiring devices are strictly not permitted to be installed.

SLIDE 3 (DAMP & WET LOCATION RECEPTACLES)

Weatherproofing Requirements:

• Weather-Resistant Type: All 15- and 20-ampere receptacles installed in damp or wet locations must be listed weather-resistant (WR) types featuring extra corrosion, UV, and cold impact resistance.

• Extra-Duty Hoods: Receptacles in wet locations require an enclosure that is weatherproof whether or not the plug is inserted, and outlet box hoods must be listed as extra-duty.

• Tub and Shower Exclusion: Receptacles are prohibited inside tub or shower spaces or within a 3-foot horizontal and 8-foot vertical zone (with specific exceptions like electronic bidet seats in dwelling units).

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

Always verify that outdoor and wet-location receptacles are marked as WR (Weather-Resistant) and paired with extra-duty in-use covers—standard indoor receptacles will fail inspection instantly!
