Final answer:
The maximum distance between outlets in corridors is typically 12 feet, as outlets are usually placed to ensure no point along the floor line is more than 6 feet from an outlet, but local codes or the NEC should be consulted for exact requirements.
Step-by-step explanation:
The question concerning the maximum distance between outlets in corridors refers to building codes which could be a matter of electrical engineering and safety regulations. The applicable standard is not stated, but generally, in many commercial installations in the United States, electrical outlets are required to be placed such that no point along the floor line (in any wall space) is more than 6 feet, measured horizontally, from an outlet in that space. This includes corridors. This typically creates a situation where outlets should be no more than 12 feet apart from each other to maintain this accessibility.
However, the exact distance can vary based on specific local building codes or the National Electrical Code (NEC). Because the standards for outlet spacing may differ based on jurisdiction and the specific use of a building, it would be important to consult the most recent NEC or local building codes for precise regulations.
