According to the NEC®, how many receptacles are required in an IEC classroom that is 36 feet by 24 feet with a 3-foot wide door?

To determine the correct number of receptacles required in a classroom according to the National Electrical Code (NEC), it is essential to consider the area of the room and the specific requirements set forth in the NEC.

In general, the NEC specifies that for general-purpose receptacle outlets in classrooms and similar educational spaces, a certain number of receptacles must be installed based on the floor area. For rooms such as classrooms, the NEC typically recommends one receptacle for every 2,000 square feet or for areas where equipment and usage justify more receptacles.

The calculation of the classroom area is straightforward: the classroom is 36 feet by 24 feet, which equals an area of 864 square feet. Given this size, it does not meet the threshold to necessitate multiple receptacles as it is under the requirement typically set for larger spaces.

Furthermore, it's important to note that doors can impact receptacle placement but do not necessarily increase the requirement for the number of receptacles. Since the door is 3 feet wide, it may also lead to consideration for receptacles placed on the wall adjacent to it, but the fundamental requirement remains governed by area.

Thus, in this case, determining that zero receptacles are required aligns with the NEC guidelines
