The code requirements for receptacle outlets in a closet may vary depending on the country, region, and specific electrical code being followed. However, in general, here are some guidelines based on the National Electrical Code (NEC) used in the United States:
General Rule: In the United States, it is typically not allowed to have a receptacle outlet installed inside a clothes closet, except in certain specific cases.
Exceptions for Specific Areas: The NEC allows receptacle outlets in clothes closets under the following conditions: a. Lighting Fixtures: A surface-mounted or recessed incandescent luminaire with a completely enclosed lamp (typically a bulb covered by a glass or plastic globe) is permitted in a closet. b. Luminaire Control Switches: A luminaire control switch (light switch) can be installed inside a closet if it is located outside of the storage area (e.g., outside the closet door or on the wall adjacent to the closet). c. Outlet for Equipment: An outlet is allowed inside a closet to power electric clothes dryers or laundry equipment specifically designed for installation within a closet. d. Transformers: Low-voltage transformers for doorbell, chime, or bell systems are allowed in a closet.
It's important to consult with local electrical codes and regulations as they may have additional or differing requirements. Always check with the local authority having jurisdiction (AHJ) or a licensed electrician to ensure compliance with the specific codes applicable to your area.
