Re: Keeping the main breaker from tripping

We ran the WCP 3CIM DS transmissions last year without any issues at all.

The biggest trick - Make sure you set up the gearing correctly for your load.
Most of the problems I have seen were based on trying to run too high of a FPS. Also USE the low gear range. I have also seen a lot of these dual speed transmissions running generally as a single speed.

We have been very pleased with these DS transmission. It just take some research to get it right.. Making sure that you are not stalling your motor for a long period of time is key.

Cooling by using canned air in a non approved method isn't safe. More than likely the trick will be illegal soon..
Perhaps adding a fan that helps cool the breaker could help, we run one for the compressor as it is..

Designing the robot with this in mind is a much better approach.

I understand using this process in a pinch but this should not be the standard solution to the issue.

Good luck this season,

Aloha!
