Yes, always.

The one on the left looks like flexible metal conduit or even AC cable(either is mostly not acceptable for use outside), the one on the right looks like smurf tube (not acceptable for use outside). Now, if the one on the right is non-metallic liquid tight conduit with a screw in fitting, then it is okay for use outside.

Was the one on the right 'spiral' looking or were the corrugations non-spiral? Non-spiral would indicate smurf tube, spiral would indicate non-metallic liquid tight - I can't tell for sure from the photo which it is.

Can anybody give me a code reference that specifically states that doorbell transformers with associated low voltage wiring are not allowed inside Main and Auxiliary circuit panels.

Thanks: Wes

Start a new thread and you will get the answer.

If you are looking for something which specifically states "door bell transformers", good luck, if you want it to be code, you will need to accept the way the code says it, in types of wiring, such as Low voltage Class 1, 2, 3.

From the 2008 NEC. (Bold and underlining are mine) (there is more to this section, but it is not applicable to the question asked)
- 725.136 Separation from Electric Light, Power, Class 1, Non–Power-Limited Fire Alarm Circuit Conductors, and Medium-Power Network-Powered Broadband Communications Cables.
- - (A) General. Cables and conductors of Class 2 and Class 3 circuits shall not be placed in any cable, cable tray, compartment, enclosure, manhole, outlet box, device box, raceway, or similar fitting with conductors of electric light, power, Class 1, non–power-limited fire alarm circuits, and medium-power network-powered broadband communications circuits unless permitted by 725.136(B) through (I).
- - (B) Separated by Barriers. Class 2 and Class 3 circuits shall be permitted to be installed together with the conductors of electric light, power, Class 1, non–power-limited fire alarm and medium power network-powered broadband communications circuits where they are separated by a barrier. (Jerry's note: And that barrier is a grounded metal barrier separating the different systems, and is approved for use in that enclosure, raceway, etc., i.e., you cannot just cut a piece of sheet metal and say 'this is the barrier', it has to be manufacturer specific and for their equipment.)
- - (C) through (I) do not apply to the question being asked.

Now where will you find where it specifically states "door bell transformers" are allowed anywhere, or disallowed anywhere. That is Class 2 wiring and must meet Class 2 wiring requirements.

So, what's with this Jeff Eastman guy? No profile. He posts questions and then deletes them. What is the point?
