Specific-Purpose Branch Circuits

SLIDE 1 — 265.4

265.4 — OTHER ARTICLES FOR SPECIFIC-PURPOSE BRANCH CIRCUITS

Article 265 gives us the general requirements.

But what if the branch circuit supplies specific equipment?

That's where 265.4 comes in.

Certain equipment and applications have additional or modified requirements found elsewhere in the NEC.

⚡ Think of 265 as the starting point — not necessarily the only article you'll need.
