My concern was the unbalanced load. possibly putting an un due strain on the motor, and cutting its expected life. Also I'm not disagreeing, but did Fed pacific use all the quality panel parts in Canada and ship the bum ones throughout the U.S ?? I've witnessed a 20amp 277volt short dead to ground and the breaker never tripped, it welded the mc jacket to the ceiling grid and made some bad burn marks? I don't know why nothing tripped? but it got my attention. and I always triple check Fp breakers cause some in my expierience don't snap open when you shut them off. Just my2 cents.
