EPISODE 7 — ANNEX C: THE SHORTCUT

SLIDE 1 — THERE'S A FASTER WAY

What if all your conductors are the same size and type?

👀

ANNEX C

can save you some serious math.

SLIDE 2 — ANNEX C

Annex C contains tables for maximum conductor counts for particular raceway/conductor combinations.

So instead of calculating every conductor individually...

You can potentially:

LOOK UP THE COMBINATION.

⚡ BUT READ THE TABLE CAREFULLY.

SLIDE 3 — THE CATCH

Annex C isn't your answer for every conduit-fill problem.

If you're dealing with:

❌ Mixed conductor sizes
❌ Different conductor types
❌ Different configurations

You may need to return to:

CHAPTER 9 TABLES 1, 4 & 5
