The hydraulic pump is rated at 100 amps. Wiring on our hydraulic unit is #6 stranded cable and can handle that amperage. I believe the hydraulics are running right on the edge with a 50 amp breaker. We had no problem until I installed a new cylinder, which was tighter than the old one. Breaker started tripping when bringing the slides in. I couldn't find a 50 amp breaker where I was located, so I merely paralleled a 30 with the 50. End of problem.
