Hey fellows I am still trying to get my new shop up and running. I got all of the necessary wire ran and the recepticals ready to go. What I need a little help with is finding the proper breakers for my breaker box. My shop has 3 phase power and apparently also has single phase too as my single phase machines work fine on the limited number of existing outlets. My breaker box is shown in the pics below. It is a 3 phase box, and I need to find the proper type of breakers to run some 110v and 220v lines that need to be wired using one or two of the legs depending on whether it’s a 110v line or a 220v line. Can some of you electrician minded folks help me find the proper breakers for this box? I need to be able to connect 5 additional 20amp 220v lines, one 30amp 220v line, and five 15amp 110v lines. If you guys could provide some links for breakers that would work on this 3 phase box I would be very appreciative.

Just going by Panel type, These fit, but, I’d pull one of the breakers out and verify that its the same type before ordering.

The best place to find those breakers would be in the back of the electrician’s truck.

Ditto on Kazooman. No one likes a shocking experience especially one of that magnitude. larry

You need to go to a real electrical supply house that sell Cuttler Hammer.

Thanks guys! I tried my local electrical supplier and they said that they don’t have much experience with anything 3 phase, and that they do not employ any licensed electricians. So they were not much help. You have to remember that I live in rural Arkansas. I will contact a local electrician and see if he can help me on this.

Glad to hear that! If the locals cannot handle the job it is a sign that you should proceed with caution. You might need to bring in an electrician from a distance to be certain that everything is installed and sized appropriately. If you provide them with all of the information you showed above they should be able to arrive on site with the correct breakers so you can avoid paying twice for travel.
