Code references please??

[jahilliard]

Sad to say I am very very rusty with residential code references so if I could have some assisstance this time I would really appreciate it. 1)Where does the NEC reference recep requirements for stairwells? 2) Where, if at all does the code require or mention "ufer" grounds? 3) Smoke Alarms required at top and bottom of stairwells? Thank you so much! trying to clear this up quickly.

1)Where does the NEC reference recep requirements for stairwells?

210.170(A)(2)(a) this is applies to dwelling units only. There may also be some requirements in the building codes.

2) Where, if at all does the code require or mention "ufer" grounds?

250.50 and 250.52(A)(3)

3) Smoke Alarms required at top and bottom of stairwells?

The placement of smoke alarms is not located in the NEC. This requirement comes from the building codes.

I'm assuming you mean 210.70. And i see lighting outlets referenced but I was actually asking about receptacle requirements, should have been more specific.

There are no requirements for receptacles in a stairwell

Your right, I meant 210.70 and that section is dealing with lighting outlets.

There is no NEC requirement for a stairway to have a receptacle.

NO requirements? Not even when there are landings? just making sure.

Nope, not even for landings. (Unless the landing happens to be a hallway that is longer than 10 feet.)

not unless your "landing" is long eniough to be a hallway, or big enough to be a balcony

Requirement for wall receps only apply in the following rooms

210.52(A) General Provisions. In every kitchen, family room,
dining room, living room, parlor, library, den, sunroom,
bedroom, recreation room, or similar room or area of
dwelling units, receptacle outlets shall be installed in accordance
with the general provisions specified in 210.52(A)(1)
through (A)(3).

This was pretty general.... I meant to say for general wall spacing rules...

jahilliard,

Please take my post with the best of intentions because that is definately how it is meant...

I only mean to point out that the questions you have posed (regarding references) only just begin to scratch the surface with regards to the vast amount of specific NEC requirements to which dwellings are subject to.

In addition, some those specific requirements can vary considerably from the 2002, 2005 and the 2008 NEC Code cycles.

If you are beginning a dwelling project, I would recommend your serious review of the applicable NEC version (cycle) for your jurisdiction. Proper planning and awareness of the minimum NEC dwelling requirements can save you considerable time and expense. ...not to mention...misery ...

I do hope this is helpful, and good luck on your project,

I believe the code refers to them as concrete-encased electrodes or some such.

Correct, UFER is a slange term for a Concrete Encased Electrode. The term UFER referes to Herbert Ufer, the electrical engineer that developed the concrete encased electrode during WWII.
