    50A, Single Phase

    We need to hook up a 110v, single phase, 50A fryer to a 100A, 110v/220v, single phase panel. A few flourescents will be on during the fryer's operation, but not much else. Will this cause any sort of unbalanced load? (110v, single phase, 50A - it's all we could get at the moment)
