    I believe Belimo makes any and all types of damper and valve motors in all voltage ranges.

    Ruskin and Honeywell have both 120V and 24V.
    Usually the bigger the damper the more likely you are to see 120V spec's
    If common sense is so common how come so few of us have it!

    Not a problem if it's big enough. This one was 40va.
    Tracers work both ways.

    For the same reason I'd guess that most HVAC guys couldn't answer off the top of their heads, how many of a particular size wire can, by code, be run through a given size of conduit? It's something that's usually not needed for us to know to earn our pay. I'd like to learn more about their buis, but is unlikely as I haven't finished with this one. And my earplugs are slippin already.

    The "fill" percentage of the conduit is dependent on how much current the conductors are sized for compared to how much they are carrying and the insulation type of the wire inside of it.

    You can never be more than 80% normally.

    Thanks,
    The electrical comes in handy sometimes, but it is hard to stay current with the code changes if you don't do it every day.
    Good luck on the plumbing.
