The big snap action breakers are rated 40A. The main breaker is rated 120A. If you have four or more snap action breakers in roughly equal use, the main breaker and brown out are more likely to be an issue than an individual breaker. The advantage to having more small motors is that you are more likely running them nearer peak efficiency, and also spreading the waste heat around better.
