Episode 2: Feeders, Branch Circuits & Receptacles (590.6(A) – 590.6(C))

SLIDE 1 (HOOK / COVER)

⚡ NEC Quick Hit: Temporary Feeders and Circuits (Part 2) ⚡

Using NM/SE cables anywhere, hard-use extension cords, and separate lighting circuits—let's check Section 590.6 parts (A) through (C)! 👇

SLIDE 2 (FEEDERS & BRANCH CIRCUITS)

Permitted Temporary Conductors:

• Flexible Cords & Cables: Feeders and branch circuits can use cable assemblies or multiconductor cords identified for hard usage or extra-hard usage per Table 400.4.

• NM and SE Cable Permissions: Types NM, NMC, and SE cables are permitted in any building or structure without construction type limitations and without concealment within walls, floors, or ceilings.

• Laying Cords: Hard-use or extra-hard-use extension cords are permitted to be laid directly on the floor when protected from accidental damage.

SLIDE 3 (RECEPTACLE AND LIGHTING SEPARATION)

Keeping Power and Light Independent:

• Grounding Requirements: All temporary receptacles must be of the grounding type, connected to a separate equipment grounding conductor or continuous metal raceway/cable.

• Lighting Separation: On construction sites, receptacles shall not be installed on any branch circuit that supplies temporary lighting.

• Why Separate? This ensures that an overcurrent trip or GFCI activation on a power receptacle does not plunge the work area into darkness.

SLIDE 4 (WRAP-UP)

💡 Apprentice Pro-Tip: Never combine temporary lighting and receptacle loads on the same construction branch circuit—losing power shouldn't mean losing your jobsite lighting!
