	In most places, homeowners are allowed to do their own wiring.
	In some, they're not.  Check with your local electrical
	inspector.  Most places won't permit you to do wiring on other's
	homes for money without a license.  Nor are you permitted to do
	wiring in "commercial" buildings.  Multiple dwellings (eg: duplexes)
	are usually considered "semi-commercial" or "commercial".  However,
	many jurisdictions will permit you to work on semi-commercial
	wiring if you're supervised by a licensed electrician - if you can
	find one willing to supervise.

	If you do your own wiring, an important point:

	Do it NEAT and WELL!  What you really want to aim for is a better
	job than an electrician will do.  After all, it's your own home,
	and it's you or your family that might get killed if you make
	a mistake.  An electrician has time pressures, has the skills
	and knows the tricks of the trade to do a fast, safe job.
	In this FAQ we've consciously given a few recommendations that
	are in excess of code, because we feel that it's reasonable,
	and will impress the inspector.

	The inspector will know that you're an amateur.  You have to
	earn his trust.  The best way of doing this is to spend your
	time doing as neat a job as possible.  Don't cut corners.
	Exceed specifications.  Otherwise, the inspector may get extremely
	picky and fault you on the slightest transgressions.

	Don't try to hide anything from the inspector.

	Use the proper tools.  Ie: don't use a bread knife to strip
	wires, or twist wires with your fingers.  The inspector
	won't like it, and the results won't be that safe.  And it
	takes longer.  And you're more likely to stick a hunk of
	12ga wire through your hand that way.

	Don't handle house wire when it's very cold (eg: below -10C
	or 16F).  Thermoplastic house wire, particularly older types
	become very brittle.

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.

Regarding new construction wiring and running 12/2 and 14/3 wire in the same box.

I have multiple switches to lights. Ran 12/2 and 14/3 into switch box and inspector wrote correction needed.

What should I have done instead?

thank you

Does a grounding electrode facilitate the operation of a OCPD, to clear a ground fault ?

Assuming you are installing two switches in a two switch box, you probably should have used 14/2 and 14/3 instead of replacing 14/2 with 12/2. If you are only installing one switch in a one switch box, you should only have one cable in the box.

I prefer to use nothing smaller than12 awg /the smallest sized wire on a circuit determines the allowable ampacity
Ex: 15 amp-14awg. 12awg-20amp only rule for thumb other factors such as continuous load,heating and others if you do not know the safe NEC rules then please call a qualified journeyman Electrician better be safe
