How to determine doorbell wire gauge

I'm going to install a Ring doorbell, but I'm moving the location of the wired doorbell about a foot away from its current location. I need to add a foot or so to the doorbell wiring. I've read that doorbell wire is 18-, 20-, and 24-gauge wire. I hate to ask what to some might seem like a dumb question, but how do I confirm the gauge of the wire that's currently installed? The house was built in 2009. I don't think there's enough there to read anything on the wires. Thanks.

The smaller the number the thicker the wire. If you're not sure always go thicker. It can handle more current. For a door bell wire system it's no big deal.

I normally use 18ga for doorbell (and thermostat) wiring.

Garbage Disposal Wiring

Hi All, I am selling my house and was requested by the buyers to not have exposed romex under the sink for the garbage disposal. What options do I have to make the wire not exposed? Any ideas would be appreciated!

generator and welder on same circuit

wwdubose on Feb 16, 2018

I currently have an outlet wired in my shop with 10/3 for my generator that goes to a double pole 30 amp breaker in my sub-panel (red and black goes to breaker, white to neutral bar, green to ground bar). I only use this to plug my generator into for back-powering the house (not used other than that). I am getting ready to purchase a welder and want to put the NEMA 6-50 welder outlet and the 4-prong generator outlet on the same circuit and use a 40 amp breaker and #8 wire. If I were to just have the welder on the circuit by itself, I would use 8/2, versus 8/3 for the generator outlet. If I put them on the same circuit, would I just run 8/3 to the 4 terminals of the generator outlet, then tie into the ground red and black and run 8/2 from there to the 3 terminals on the welder outlet?
