sink motion detectors Gfi protected?

[thetacon]

in a commercial bathroom that has motion activated
water at the sinks is the circuit feeding the transformer required to be gfi protected?. The plumber supplied a transformer that was hard wired 120 volts on the supply side and delivered 12 volts on the load side. The one transformer supplied the power to the sensors on 3 sinks. If the transformers were the individual type that plugged into an outlet then the receptacle would have to be gfi protected. but in this case with there being no receptacle just a hardwired transformer mounted under the sink behind a fixed panel what is code compliant in this situation?

thanks

I say no, GFI just for the recepts.

I did not think so either but I failed a final due to it.

What did the installation instructions say??

no install paper work with the transformer . the code correction i have not seen i am headed to the shop now to have a look

From the '05 (change from '02 added 2 outdoor locations, irrelevant here)

210.8 Ground-Fault Circuit-Interrupter Protection for Personnel.
(B) Other Than Dwelling Units.
All 125-volt, singlephase, 15- and 20-ampere receptacles installed in the locations specified in (1) through (5) shall have ground-fault circuit-interrupter protection for personnel:
(1) Bathrooms

Your xfmer is hard-wired...

what is code compliant in this situation?

A competant inspector...

GFCI in bathrooms is required only on receptacles. No receptacle, no GFCI required. Things that are hard-wired are more likely to be properly grounded (bonded) than items that plug in (where the installer may break off the ground prong of a plug for example). Proper grounding (bonding) trumps GFCI every time.

Besides all the other responses a GFCI would really be pointless as it can not protect the circuit on the secondary side of the transformer.

thanks everyone, all of the above listed reasons were why i did not put them on a gfi. The inspector failed the final without citing a code violation. we switched them at the generals request rather than fight it so that they could get the bathrooms up and running. now there is a one more misinformed inspector on the loose.
