SLIDE 1 (HOOK / COVER)

⚡ NEC Quick Hit: Resistors & Reactors (Part 1 - Article 470) ⚡

System scopes, component exclusions, and the surprising split on reconditioned equipment—welcome to Article 470! Let's break down the fundamentals! 👇

SLIDE 2 (SCOPE & EXCLUSIONS)

What Article 470 Covers & Excludes:

• General Scope: Article 470 covers the installation of separate resistors and reactors on electrical circuits.

• Apparatus Exclusions: This article does not cover resistors and reactors that are built-in component parts of other apparatus.

SLIDE 3 (RECONDITIONED EQUIPMENT RULES)

The Reconditioned Equipment Split:

• Reactors Permitted: Reconditioned current-limiting reactors are permitted to be installed.

• Resistors Prohibited: Reconditioned resistors shall not be installed under any circumstances.
