Hi,
I need to run a #10 cable across my garage ceiling for a water heater and have 2 questions.
2) The heater manual only shows the 2 hot legs and a ground, no neutral, is this right or have they just simplified the drawing?
Thanks

Romex is OK exposed in an unfinished space if it's fixed in a protected enviroment, such as, stapled along the side of a beam where it's not likely to be damaged.
220 volt resistive heaters, like water heaters, baseboard heaters do not need a neutral.
Don't know your local codes, but as a matter of plain common sense running conduit would be better in a garage. Looks more professsional, too. HTH

A good compromise is ENT (AKA Smurf tube). That is the flexible blue stuff.
It depends on your local codes. In many places romex is ok above 8' but anything below that level needs to be protected. Steve B.
Thanks too all for the info and tips.
