USA electrical code allows multiple 15A outlets (one duplex outlet is a multiple outlet) on a 20A circuit. One simplex 15A outlet must go on a 15A circuit.Yea scary...Looks like the neutral contacts inside the outlet were arcing? Were you plugged into the top or bottom? What did the plug look like? Maybe the plug or outlet contacts were a bit old and tarnished?
I believe, 15A outlets on a 20A circuit are allowed (in USA anyway) but not 20A outlets on a 15A circuit.
