Thanks for the ideas!

I thought about the subpanel, but I don't get how I could do the separate breakers. The contactor has 3 feed lugs, L1 - L3 and 3 output lugs T1- T3. It's 240V so I need two lugs for hot, right? Seems like the L3 and T3 are for using the contactor in a 3 phase system, so I don't need them.

Not the right one. The contactor is GE and it's definitely a 208/240V coil, and so is the thermostat. I don't have the parts in the house anymore to give the numbers, but I am sure they are all 240.

When I'm saying 30A breakers, I mean 2 240V 2 pole 30A breakers. It's all 240V. And when I say I have 2 systems, I have two completely seperate systems. Each with 3 heaters (which are each self-contained not multiple elements in one appliance), a 60A contactor and a line voltage thermostat...

Thanks for the quick response, and you are right, there is little info on that link. Also little info came with the components. The contactor is a 60A, with a 208/240V switch, and the contactor is 1 or 3 phase, up to 480V I believe. Heaters are CH-57 (3000 watt) and I have 3 right now...

I am finally getting around to this, and have decided to run 2 30A circuits using #10 THHN though EMT - planning ahead for adding a 4th heater in the future. My question involves the contactor. Since both circuit breakers are connected to the same lugs in the contactor, and the heaters are...

Thanks for the help.

I have pulled Romex through conduit and you are right - it *****! How many #12 THHN can I run through 3/4" conduit? I don't mind running the wire for 3 circuits (probably actually 4 in case I add another heater - the contactor can handle 4), but I don't want to run 3 (or 4) runs of conduit...

My building is all steel, so I will be using conduit anyway. I'll price it out with #8 THHN vs #6 Romex vs 3 runs of #12 romex. I have to go pretty far, almost 70 feet to the longest run. I am installing this in a 30 X 40 space, and actually have 2 of these "systems" with 2 thermostats, 2...

aceman, thanks again. I understand now. Dr. V got these same heaters and wired one temporarily to see how they work and wasn't thrilled, so he's just suggesting that I try that before going through all the trouble. With this type of heat, recovery is not good. I get that and plan to leave...

aceman - thanks for the quick reply. The contactor actually has a 208/240 volt coil. And I thought part of the purpose of using a contactor panel was so you didn't have to run a circuit to each unit? Or is it purely a control/relay? FYI - each of the heaters is 12.5 amp at 240V, and the...

I realized this probably isn't the right forum for this, so I posted in lighting and elecrical: http://www.garagejournal.com/forum/showthread.php?t=26016 -Travis

I'm new to the forum but it has come up in a lot of searches as I try to get my shop setup. What a great place! I just got my shipment of 3 infrared heaters with line voltage thermostat and contactor panel...

I just got these infrared heaters today. It's already cold in MO so I want to get them installed pretty soon. My problem is I wired my shop myself, but I am not an electrician. So I was bummed to see that none of the items came with wiring instructions. Can someone give me a quick idea of...
