Bill,
I do some real-eatate related work, and the local twp. inspectors are requiring GFCI protection on laundry room receptacles, and on sump pump receptacles befor they will issue a occupancy permit. I think there may be enough stray leakage current from some of these motors to cause nuisance tripping, and in the case of the sump pump, a major problem developing when the pump loses power when its needed most.
