Why?

If we look at the spec sheet - http://www2.usfirst.org/2005comp/Specs/Globe_Motor.pdf, it shows a stall current of only 22A. If you look at the snap action circuit breaker spec sheet, it shows it needs 10 full seconds at the circuit breaker rating to blow. Therefore, I see no problem with running the Globe on a 20A breaker, and using a spike, if you don't need speed control. This could save a team nearly $100, if they didn't have to buy another speed controller.
