Doorbell wire - safe on exterior

[Mark Lloyd]

I looked at the transformer for my doorbell. The secondary is marked "16V". The measured voltage is 19.3VAC. The wire connected to it looks like 24 gauge.

And seems excessive for just the low-voltage circuit for a doorbell. Those transformers probably can't put out more than 1A or so. 24 gauge should be suitable.

Your link brings up a page of electrical generators and appliances.

I'm not talking about the little mechanical toy types, either. I've been to Home Depot and I've seen the wireless units. A receiver/bell you stick on the wall like a regular bell unit, and 2 doorbell-switch-sized transmitters you mount at each door. That's the kind that was apparently installed here at one time.

My point still stands; I *don't* consider wireless units to be suitable for rental units because it's *too easy* for a light-fingered tenant to make off with a working doorbell system.

Screw the bell, put on a knocker
