Do you have any with the 110v coil. If so, how much for three shipped to 14845?
Thanks

Zeus, I bought a few of these off you before, I was curious if you still had any left and could do a pickup again. Believe I need 3 of the ones that'll do 30a.

Dan,
I do not have any C30's currently, but I do have a few C23's left. What size elements are you using? If they are 5500W or under C23's will work for you. Read post #58 for more details. Wednesday or Thursday works best for me to meet up. Let me know.

I need help. I purchased 4 C30's last year, but just now getting around to wiring my control panel. (I'm posting here because I thought I could get someone who used these actual contactors.)

The plan is to use 2 of the C30's together to bring in the 50a service. Then the other 2 to be used on each of the elements.

I understand the element wiring concept just don't know exactly where to stick the wires. Can someone please post a really good pic or an easy to follow diagram?

Now, combining the 2 contactors to bring in the 50a service is where I'm really confused. Can this be done, and obviously, if so, can someone please explain.

Thanks in advance.

The C30's are rated for 28 amps. I don't see how you're going to use them for 50 amp service. Basically, each connector is rated for the 28 amps. There's no way to split 50amps between 2 different connectors. You need the right equipment to handle that kind of amperage.

As far as wiring the coil is concerned. Attach a hot to one side of the coil terminal (they are below the larger terminals and there are 2 of them) and a neutral to the other side.

Here's a pretty good picture:


I use L1 and L2 for the 2 hots. In on one side and out the other. I am only using 2 of the 3 terminals of the contactor.

Then there's the smaller wires for the coil below them (black and white smaller wires).

thanks stlbeer. great picture!

As for the 2 c30's for the 50a service, I made an assumption based on a diagram from ebrewsupply. It appears that he is using two 40a contactors to pull in the 50a service. I was really just double checking, but sounds like I may have been mistaken on how to use the contactors.

Ah - I see now. Neither circuit will pull more than 40 amp so there are 2 contactors per circuit. I've seen designs where there is 1 contactor for the keyed circuit which means it must be capable of providing the full capacity of the control panel.

If you are wiring it like your drawing you'll be just fine. i.e. your concept will work as you have planned.
