In a house we are finishing now, we discovered a wire in one of the recep boxes that the alarm people had put there. Its a 22ga. 2 pair wire. What would be the purpose of this and isn't it a code violation?

Most likely it is for the plug-in power supply for the alarm panel.

Yes, this is a code violation. It should be removed.

Hopefully, it's a mistake.
Unless the insulation of the 22 ga is rated the same as the other conductors within the box, it's a code violation. Is it a 1 gang box?? What else is in the box?? Sources??
Maybe the alarm guy intends to put the 22 ga on the transformer that he's going to "plug in" your receptacle, and he ran the 22 from the alarm panel, and "hid" it in your box.

ga.sparky56...i think it for the secondary wiring of the transformer. (that plug into the receptacle.)

they may have put it in there so they can get to it later after the drywall is installed.

Hotline, its a 1gang recep box located in a hallway/stairway, it has 2 12/2's in it. Its on a ckt that serves acouple of storage rooms and this stairway/hall. I provided a recep in the waterheater room for their alarm panel. What code section is this in? Ineed ammunition to argue my case because there is no inspection in the county the job is in.thanks for the help. Russell.

I'm in GA too and they do that crap here! Want to get em, just put a decora style recept there and they want have a way to secure tha x-former! It is a violation but I'm afraid it is common practice around these parts. Let me know what your inspector says.

Upon closer examination, we discovered thathe sheetrocker had caught the alarm wire with his router. Only about 1 inch of the wire is undamaged. Possibility of great wailing and gnashing of teeth by alarm man! [Linked Image]

If it Class 2 wiring, it must be installed per 725.52.

If wanting to change to Class 1, the existing Class 2 must be in Chapter 3 wiring method. 250.52(A)Ex2.

There may be other requirements also.

So, ga.sparky56, it was the sheet rocker after all. C-o-n-s-p-i-r-a-c-y!

Seriously, of what use is such a cable (others mentioned it as coming from the alarm unit's transformer) within the box containing the receptacle? I mean, as mentioned, they wouldn't connect 22AWG conductors directly to the circuit that is feeding the receptacle. (Well, hopefully not.)

arseegee: Do you mean they use the box to "store" their cable until they are ready to use it?
