Electrical Protection Requirement for a Hairdryer Near a Sink

  Is it legal to have two separate circuits supplying power to the same duplex outlet? No other devices are present in the box. I understand that the tabs must be removed connecting the two hots together as well as the tabs for the neutral. I also thought it would be safer if the two circuits are on a double pole breaker. Therefore disconnecting the supply to both circuits at the same time. I am asking this because my wife’s hair dryer (1800W) keeps tripping the 20A breaker while other appliances are running. I just want to add a 12-2 wire not set it up as a multi wire circuit 12-3. This outlet is in her beauty shop not a bathroom.

Thanks for your electrical question Jeremy.

Yes Jeremy this can be done but keep in mind that if this outlet will be within 6 feet of a sink then the outlets require gfi protection.
