I have done it on several occaisions. However, it really depends on the amp rating of the the circuit breaker it is on and what the amp draw/wattage of the all the equipment on the entire circuit. What are you running on that circuit.....(the entire circuit..there may be other appliances..lights/refrigarators, etc on other outlets that are on the same circuit that the outlet that you wish to use is on)
Yeah what ghouston said!
