Episode 2: Wiring Methods, Disconnects & GFCI Protection (682.13 – 682.15)

SLIDE 1 (HOOK / COVER) ⚡ NEC Quick Hit: Pier Wiring, Disconnects & GFCI Rules (Part 2) ⚡ 

What wiring methods are permitted on floating piers? Where must the equipment disconnect be located relative to the shoreline? Let's break down Sections 682.13 through 682.15! 👇

SLIDE 2 (PORTABLE POWER CABLES & WIRING METHODS)

Extra-Hard Usage on Piers:

• Wet-Rated Wiring: Wiring methods must be suitable for wet locations and include an insulated EGC.

• Portable Power Cables: Extra-hard usage portable power cables (rated 75°C, 600V with a "W" suffix) are permitted as permanent wiring on the underside of piers and where flexibility is needed across floating sections.

SLIDE 3 (DISCONNECTING MEANS & SHORELINE RULES)

Readily Accessible Cutoffs:

• Location: Disconnects must be readily accessible on land, located not more than 750 mm (30 in.) from the receptacle, within sight of (but not closer than 1.5 m (5 ft) from) the shoreline, and elevated 12 inches above the datum plane.

SLIDE 4 (WRAP-UP)

💡 Apprentice Pro-Tip: All branch circuits supplying outlets up to 150V to ground and 60A require GFCI protection, and feeder/branch circuits on piers require ground-fault protection not exceeding 30 mA to prevent electric shock drowning!
