I have never had to wire an automatic faucet before, and the plumber has no spec sheet. I am finishing the rough tomorrow, and I don't know what to do for the faucets? Any help?
Thanks

Depends on the faucet. Most likely the sensor is in the faucet and all you will need is a receptacle under the sink. There are some that have a separate sensor that goes on the wall, but you could always fish that in later.

Make sure you check the specs provided !
Most of the ones I have dealt with give an EXACT location for the electrical connection. Sinks are easier then toilets and urinals.Toilets and urinals have a location tolerance of about 0% they must be dead on.

the ones I've worked on needed 24volts under the sink
