We have a 460 3 ph machine that I just switched to 230, I swithced the jumpers at the block and the jumpers at the transformer, ran for 3 minute sthen shuts off-

I think the problem is the heaters are being overloaded and tripping. An electrical guy helped me figure they are in fact underated now that I am running low voltage, here is my question: Should I just replace the contactors as the heaters are 58 bucks each, i need 6 because there is a grinder motor and a pump motor- Or should I get a step up transformer, or 2 new cutler hammer starter contactors with a higher amp rating?

If you have time to ponder and give input it would help- If you are in Maryland and you want to trade your time for woodworking tooling: shaper cutters, router bits etc. let me know!

Thanks
