## Questions & Answers

**Q: What size hole would need to be drilled for the wiring to go through? Thanks.**
A: I'm not sure of the size drill hole, its been a while since I installed it but pretty small

**Q: What’s the measured actual open-circuit voltage (no load)?**
A: not now

**Q: can this be used outdoor? i.e. the outlet is outside.**
A: It is not water resistant but it is sealed up.  Probably not a good idea for an outket that is exposed directly to the elements.

**Q: Does this wired work for any smart wired doorbell ?**
A: If it takes the voltage and amps this puts out.  Those are in the description.  Match em to your doorbell device, or search with your doorbell name, and it should give you results for that specific bell, if different!
