No. You have two breakers, one for the hydraulic pump, which is the slides and the jacks, and the other breaker is for everything else in the rig. When I replaced the breaker to the pump, I did not replace the other breaker. I also do not remember where the other wire goes off the load side of the 80 amp breaker, just wired it the same as it was wired on the old 40 amp breaker. I also found some loose connections when I installed the new breaker, so it's a good idea to check everything you can while doing this.
