## Questions & Answers

**Q: Is there a lock nut which allows it to attach to a junction box?  I don't see it in the picture?**
A: Hi...My 122c is attached to my electrical box downstairs.  It does a lock nut attached but not sure if that came with the product or my electrician installed one.

**Q: Is this video doorbell compatable like ring or arc**
A: This can be used for video doorbells.

**Q: Will this work with in place of a new Nutone 10 Volt transformer Model 515T?**
A: Generally yes, It appears so. Both have a rated output of 10V 25VA which means both hookup to a 120Vrms source, or just your normal wall outlet. But im not sure what your doing exactly so im not sure if the dimensions are the same ect. Try comparing the datasheets for that.

    Works with SkyBell doorbell
  

*by C***Y on Reviewed in the United States on February 7, 2019*

I had issues with other transformers until i was able to find this one. This has worked great and hasn’t heated up or made the door bell ring continuously. I had these issues when i installed my Skybell door because I didn’t have the right transformer. I installed this one and it works perfectly now.

    Never Used
  

*by D***S on Reviewed in the United States on July 30, 2013*

Bought it for a camera system, but never installed it. It is still in the original package, so don't know anymore about the transformer.
