NEC 230.24(B)

NEC 210.8(A)(3) / 406.9(B)(1)

Outdoor receptacles at dwellings require GFCI protection per NEC 210.8(A)(3) and must have an enclosure that is weatherproof whether or not the attachment plug cap is inserted (in-use cover) per NEC 406.9(B)(1). There is no NEC minimum height requirement for outdoor receptacles, though local codes may specify one. The installation meets code with GFCI protection and a wet-location in-use cover.

NEC 210.8(A)(6)

ALL kitchen countertop receptacles require GFCI protection, regardless of distance from the sink. NEC 210.8(A)(6) requires GFCI protection for all 125V, 15A and 20A receptacles that serve countertop surfaces in kitchens. The 6-foot rule applies to sinks in other locations — in kitchens, it is a blanket requirement for all countertop receptacles.

NEC 210.8(B)(7)

All 125V, 15A and 20A receptacles installed within 6 feet of a sink edge in commercial occupancies require GFCI protection. Break room sinks in commercial offices are treated the same as kitchen sinks for GFCI purposes.

NEC 230.95

NEC 230.95 requires ground-fault protection for equipment (GFPE) on services rated 1,000A or more at 480V. In a high-rise electrical riser, a ground fault without GFPE can cause an arcing fault that escalates into a fire within the riser shaft, potentially disabling power to multiple floors before being detected.

NEC 240.86 / high-rise office Specification

The high-rise commercial office specification explicitly prohibits series rating of overcurrent protective devices. All existing panels being re-utilized must use fully rated breakers — meaning each individual breaker must have an interrupting rating equal to or exceeding the available fault current at the panel (22kAIC in this case). Series rating is prohibited because in a multi-tenant high-rise, a fault that exceeds a branch breaker's interrupting rating could cause catastrophic breaker failure, arc flash, and damage to adjacent tenants' electrical systems. The branch breaker must be replaced with one rated at minimum 22kAIC.

NEC 250.102

Flexible metal conduit in this size/length is not a reliable ground path; an equipment bonding jumper or an EGC must be run to bond the motor.
