2-Speed vs 1-Speed drivetrain

If you're pushing with 6 CIMs at 5 fps, your wheels will likely slip, and your main breaker will likely be OK (for a while, at least). On the other hand, if you're pushing in an 18 fps gear, your wheels won't slip, your motors will stall, and you will likely trip your main breaker quite quickly.

Quick aside question, am I right in assuming that the wheels slipping is the only thing that prevents the breaker from tripping at low fps?

For instance, if a weird situation occurred where a gearing of 5 fps did NOT slip the wheels in a pushing match, the breaker would still trip in about the same amount of time as if the gearing was 16 fps correct? Basically, the CIMs draw the same amount of current at stall regardless of the gearing so any stalling of a 6 CIM drive is just as dangerous.

Am I right in that assessment?
