NEC · 2020 National Electrical Code

§422.16 · Nameplate

Effective in NEC 2020 · NEC 2023 NW Indiana.

Plain-English explainer

422.16 (nameplate): each appliance bears a nameplate giving the manufacturer's name, rating in volts and amperes or watts, and the frequency and type of supply; the nameplate remains visible and legible after the appliance is installed.

Why inspectors flag this

A covered-up or painted-over nameplate on a furnace or water heater is a 422.16 red-tag at final; the drafter surfaces the rule so the install notes keep the placard legible.
