In general, there is no requirement to upgrade older dwellings,
	though there are some exceptions (ie: smoke detectors in some
	cases).  However, any new work must be done according to the
	latest electrical code.  Also, if you do ``major'' work, you
	may be required to upgrade certain existing portions or all
	of your system.  Check with your local electrical inspector.

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.
