Article 215: Feeders — Episode 2

Overcurrent Protection, Grounding, Tapped Conductors & Feeder GFCI

Welcome back to Article 215 — Feeders!

In Episode 1, we covered the scope of Article 215 and minimum feeder sizing. Now we're looking at how feeders are protected, grounded, and connected to other circuits.

This episode covers 215.5, 215.6, 215.7, and 215.9.

🔌 215.5 — Overcurrent Protection

Feeder overcurrent protection follows Article 240, Part I.

The feeder overcurrent protective device must be rated for at least:

Noncontinuous load + 125% of continuous load

The 100%-rated assembly exception described in the applicable requirements may allow a different calculation.

Key takeaway

Feeder overcurrent protection and feeder conductor sizing are related, but they are separate requirements. Apply the relevant rules for each.

🟢 215.6 — Feeder Equipment Grounding Conductor

If a feeder supplies branch circuits that require equipment grounding conductors, the feeder must include or otherwise provide an equipment grounding conductor for those branch circuits to connect to.

There cannot be a gap in the equipment grounding path between the feeder and the branch circuits it supplies.

Key takeaway

The equipment grounding path must continue from the feeder into the branch circuits.

🔀 215.7 — Ungrounded Conductors Tapped From Grounded Systems

This section addresses certain circuits tapped from grounded systems.

Two-wire DC circuits or AC circuits with multiple ungrounded conductors may be tapped from the ungrounded conductors of a grounded system, provided the switching device has a pole in each ungrounded conductor.

This follows the same general concept described for branch circuits in 210.10.

🛡️ 215.9 — GFCI Protection for Feeders

Article 215.9 allows GFCI protection to be installed at the feeder level as an alternative to providing individual GFCI protection for each applicable branch circuit under 210.8.

The feeder-level GFCI must be installed in a readily accessible location and protects the branch circuits downstream.

Construction-Site Application

Feeder-level GFCI protection may also satisfy the construction-site receptacle GFCI requirement described in 590.7(A).

Important Trade-Off

One feeder-level GFCI trip can interrupt power to every branch circuit supplied by that feeder.

Key takeaway: Feeder-level GFCI protection can cover multiple downstream circuits, but a trip may affect all of them.

🧠 Quick Quiz

Question: Instead of installing GFCI protection at every individual branch circuit, what alternative does 215.9 allow?

A) No GFCI protection is required

B) GFCI protection installed at the feeder level, covering everything downstream

C) GFCI protection is only required on the first branch circuit

D) AFCI protection can substitute for GFCI protection

✅ Correct Answer: B

Section 215.9 allows feeder-level GFCI protection, installed in a readily accessible location, to protect the branch circuits it supplies.

⚡ Episode 2 Takeaway

Feeders require appropriate overcurrent protection and an equipment grounding path. Article 215 also addresses tapped conductors and allows a feeder-level GFCI protection option under its applicable conditions.
