They're just heaters, nominal voltage doesn't matter that much.  I'd run a 20A circuit with #10 to each heater.  Gives you about 5% voltage drop.  It'll be fine.

Actually, I put in 230'.  Over 250' is pushing it.  Don't forget to add vertical distance also.  Keep it under 5.5%.  I'm sure the heater won't care but it will cut down on the efficiency. 

Wouldn't be a bad idea to put a little sub panel out there as Brett said.  Run a 40A/2P 240V #8s to a little 4 space panel , then you could branch off with 20A, #12 120V circuits no problem.  Its probably a wash in cost, those little panels are $30 (well they were last I knew).

if it is in conduit does it still need to be UF or can it be standard Romex?

Not suppose to run sheathed wire in conduit. THHN is what you'll need.

It's true! You pull them in together and they slide through WAY easier than solid romex or UF ever would.

so basically
1.) I run standard Romex from the panel through the rafters(bundled with the rest of the Romex for the barn) down to where I exit the barn,
2.) A junction box where it switches to THHN down through the conduit and out to the pasture
3.) Does THHN continue all the way up the poles at the end to the outlet or does it switch to Romex at some point?

Hook the conduit right to the panel. THHN all the way.

I really don't want to run that extra 150' of conduit and/or dig the trench that much further

Have you checked the price difference? It might be a lot cheaper to do it all THHN and conduit

quick calc says THHN & full 3/4" conduit will only be about $70 cheaper.. but I say not having to run that much conduit and pulling wire would be worth the extra $70

1/2" wouldn't work?  much cheaper. 


i like conduit just looks much cleaner and more commercial.  my barn all steel, so no where to staple to though either.
