Is there a minimum required spacing for electrical outlets (house keeping) along high rise commercial building common corridors? Can they be spaced further apart than the standard 12'-0" rule?
I don't know of a code requirement for normal power receptacles in a high rise, however, I have seen spacing based on a 25' cord. Suggest you check local code, ours for emergency outlets is within 10' of an exit stairs and every 100' in the corridors.
A wall receptacle is not even required by the NEC in Part III of Article 210 to serve the common corridors in a commercial building. Since there is no requirement, the receptacles when provided can be placed wherever you see fit. The branch circuit requirements in Part II of Article 210, the requirements in Article 406, and all applicable Articles in Chapter 3 would apply. Also the receptacle placements would have to meet the ADA requirements.
The 6 foot/12 foot wall spacing requirement in 210.52(A) only applies to dwelling units.
*** This is a question where NEC and IBC may overlap. One may not be able to place receptacles "wherever..."
If the corridors are fire rated, or part of a fire wall or barrier, there will most likely be spacing requirements on how far away any receptacles must be from one another (different bays). These requirements are found in the building codes, not the electrical codes. Please post back if you require more information.
I believe the intent of the question was if there was a requirement for the measured wall space between receptacles in a corridor of a public building. For that question, there is no requirement.
Chapter 27 in the IBC is titled Electrical, and it only covers emergency and standby power systems (NEC 700 & 701)
Brian, there are other chapters in IBC that relate to receptacle spacing. Got to run...
Ok, it took me a while to find, membrane penetrations are covered in 2018 IBC 714.4.2, which may dictate how electrical boxes need to be located. Of course, there are all types of exceptions that may apply; I really didn't want to delve too far into the building codes in this electrical forum. I just wanted the reader to be aware...
I'm still not clear on what is being asked, and many times corridors are required to be rated.
Also, there is a new NEC code for outlet spacing. But it only applies to meeting rooms. See new section 210.71 which basically says "do it like 210.52." But the receptacles can be anywhere, as long as they are the required amount. Most plans I see now with a meeting room or conference room do not meet this code. I reject all of them.
