NEC 408.4(A)

NEC 406.12(1)

All 125-volt, 15- and 20-ampere receptacles in dwelling-unit bathrooms must be listed tamper-resistant. A standard (non-TR) receptacle is a violation. (Note: a 15A receptacle is itself permitted on a 20A circuit serving two or more receptacles per Table 210.21(B)(3) — the defect here is the missing tamper-resistant listing, not the amperage.)

NEC 406.9(C)

Receptacles are not permitted within or directly over the bathtub or shower space (within 3 ft horizontally and 8 ft vertically of the threshold).

NEC 408.4 / NFPA 70E 205.2

A single-line diagram showing the electrical distribution system must be available to workers for safe operation and troubleshooting. Without it, workers cannot identify all energy sources, which is essential for lockout/tagout procedures.

NEC 430.1 / NFPA 90A / high-rise office Electrical Plans

Motorized dampers and motorized shades shown on the high-rise office electrical plans must be connected to the appropriate branch circuits with proper control wiring. Unconnected motorized dampers can prevent proper smoke control in a high-rise fire event, creating a life-safety hazard.

NEC 430.102(B)

A disconnecting means must be located within sight of the motor it controls so a technician can lock it out for service. None is provided here.

NEC 430.32

Each motor must have overload protection to prevent damage from sustained overcurrent. Overloads are separate from the branch circuit short-circuit protection and are typically sized at 115-125% of motor FLA.
