PART I — GENERAL

EPISODE 1 — Scope, Listing & Reconditioned Equipment (315.1, 315.2, 315.3)

Slide 1 — Hook "New article! Article 315 is where medium-voltage CABLE itself lives — Type MV conductors, cable joints, and terminations, 2001V all the way up to 35,000V AC." Text overlay: ARTICLE 315 — MEDIUM VOLTAGE CONDUCTORS & CABLE ⚡ Part 1 of 13

Slide 2 — 315.1 Scope

• Covers use, installation, construction specs, and ampacities for Type MV medium-voltage conductors, cable, cable joints, and cable terminations.

• Voltage range: 2001V–35,000V AC nominal, or 2001V–2500V DC nominal.

Slide 3 — 315.2 & 315.3

• Listing: Type MV cables, cable joints, cable terminations, connectors, and associated fittings must ALL be listed. Worth noting — the listing requirement specifically for joints/terminations/connectors doesn't take effect until January 1, 2032, so there's a phase-in window.

• Reconditioned equipment: Type MV cables/conductors, cable joints, cable terminations, connectors, and their associated fittings can NEVER be reconditioned and reinstalled. Interesting distinction: CABLE REJUVENATION (injecting fluid into an aged cable that stays in place, to extend its life) is NOT considered "reconditioning" under this rule — different process entirely.

Slide 4 — Quiz + CTA Q: "Is cable rejuvenation (injecting fluid into an in-place aged medium-voltage cable) considered 'reconditioning' under 315.3?" A) Yes, it's treated identically B) No — it's specifically distinguished from reconditioning C) Only for cables over 15,000V D) Only with AHJ approval

✅ Answer: B — the informational note to 315.3 specifically distinguishes rejuvenation from reconditioning.
