I’m working on an old Wheeled No. 28 that has a electric facer and has that junction box on the side of the frame. It trips the breaker after a few seconds of moving the carriage in fusing pressure. It doesn’t trip if I leave the directional vale in neutral. The system pressure is set to 900psi and it seems that the pump is switching HI to LOW. If anyone has any suggestion they would be greatly appreciated.

A few questions...
What is the voltage?

What is the voltage when under load?

Have you measured the amperage draw?

The voltage is 118vac with no load and under a load it’s about 115-118 VAC. I have not checked amp draw. I installed a new circuit breaker and it has seems to fix my problem.

Just reading this now. Someone correct me if I'm wrong, but shouldn't the system pressure on these units with an electric facer be set at 600 psi, not 900 psi? Perhaps that has something to do with the breaker tripping???

Originally, these units did run a lower system pressure, but many of these older machines have been fitted with a new pump and a new 1-1/2 HP motor that can handle the higher pressures. If indeed the old motor and pump are still in place, the higher pressure certainly could cause the breaker to trip. Checking the amperage would be a good way to determine if the breaker should be tripping or not.

Based on the age of this thread, my guess is that this issue was resolved over a phone call, but please update if you have further questions.
