Episode 1: Scope, Listing & Reconditioned Equipment (404.1 – 404.3)

SLIDE 1 (HOOK / COVER)

⚡ NEC Quick Hit: Switches (Part 1 - Article 404) ⚡

General-use switches, 1000V AC / 1500V DC limits, and reconditioned equipment rules—welcome to Article 404! How does the National Electrical Code regulate electrical switches? Let's break down the scope! 👇

SLIDE 2 (SCOPE & LISTING REQUIREMENTS)

What Article 404 Covers:

• Covered Equipment: Applies to general-use switches, motor-circuit switches, isolating switches, pullout switches, circuit breakers used as switches, and molded-case switches operating at voltages not over 1000V AC, 1500V DC nominal.

• Listing Mandate: All switches must be listed for their intended application.

SLIDE 3 (RECONDITIONED SWITCH RULES)

What Can and Cannot Be Reconditioned:

• Permitted Reconditioned Switches: Installation of reconditioned knife switches, switches with butt contacts, and bolted pressure contact switches is permitted.

• Prohibited Reconditioned Switches: Reconditioned lighting, dimmer, and electronics control switches (that are not wiring devices) and reconditioned molded-case switches are strictly not permitted to be installed.

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

Never attempt to install reconditioned molded-case switches in a panelboard—the NEC strictly bans them due to the critical calibration and safety testing required for modern circuit interruption mechanisms!
