The NEC requires at least two 20 amp ``small appliance
	circuits'' for kitchen counters.  The CEC requires split-duplex
	receptacles.  Outlets must be installed such that no point is more
	than 24" (NEC) (900 mm CEC) from an outlet.  Every counter wider
	than 12" (NEC) or 300 mm (CEC) must have at least one outlet.
	The circuit these outlets are on may not feed any outlets except
	in the kitchen, pantry, or dining room.  Furthermore, these circuits
	are in addition to any required for refrigerators, stoves, microwaves,
	lighting, etc.

	New rule (1996 NEC): all counter outlets must be GFCI protected.

	(Old NEC rule for historical purposes) Non-dedicated outlets within
	6' of a sink *must* be protected by a GFCI.

	Split duplex receptacles are fed with a 220V circuit.  The tab
	is broken on the hot side of the outlet, and one hot goes to
	the upper outlet, and the other hot goes to the lower outlet.
	The neutral connects to both outlets through one screw.  When
	"carrying through" to another outlet, the neutral must be
	pigtailed, such that removing the outlet, or having the neutral
	connection fall off or burn out doesn't cause the neutral to
	disconnect from downstream outlets ("loose neutral" problems -
	see "What does it mean when the lights brighten...").

My daughter dropped a small necklace behind her dresser. The necklace crossed a plug terminal and shorted the receptacle.

I bought a new receptacle and installed the same. I still have no power  I suspect there could be a bigger problem,this is aluminum wiring.

I've killed the breaker and call an electrician but am curious as to what happened.P.s. there is a dimmer switch on the same circuit.
