I currently have one 20A circuit feeding my dishwasher and garbage disposal. The garbage disposal is also switched. There's a 12AWG wire hard wired into the back of the dishwasher, and the source also goes to a switch by the sink. Then there's a 12/2 wire that goes from the switch to an outlet under the sink for the disposal.
I have a automatic faucet that requires power. I've been using batteries for a while, and I just recently got an AC adapter so that I don't have to change batteries so often. Now I just need to find a way to wire it.
My plan was to take the wire that's going into the dishwasher and feed it into the area under the sink (the dishwasher is immediately adjacent to the sink), then add a small junction box and receptacle and send the wire back to the dishwasher. All I plan to plug into this receptacle is that AC adapter which provides 1Amp at 12 volts DC, so a miniscule amount.
My questions are:
- Can I do this?
- Is it safe?
- Is it up to code?
- If not, is there a better option?
Edit to add more info requested in comments:
- I'm in Utah.
- The dishwasher's tag lists:
Total Amps: 9.6
. - The disposal is 1/3 HP. The label says 5.6 Amps.
