I didn't mean to be unfair, Mac. My main point with this thread was to show the need to know something about other trades.
Several times, I have seen pics like the first one in the trade press, followed by the assertion that, since there is no conduit for the T-stat wire, it must be in with the power conductors. It is then asserted that doing so is aviolation of the NEC- mixing of control and power circuits.
Without getting into a discussion of wheter the thermostst wire is a power limited circuit (to which that rule wuold apply), I wanted to show that the assumption behind those trade-press pics was wrong.
Indeed, some systems don't even have a control wire to the condenser.
We have to work with other trades all the time- and we can do that better if we have a basic understanding of their trade!
