	Every electrical device or component must be certified by the
	Canadian Standards Association (or recognized equivalent) before
	it can be sold in Canada.  Implicit in this is that all wiring
	must be done with CSA-approved materials.  They perform testing
	similar to the UL (a bit more stringent), except that CSA (or
	recognized equivalent) approval is required by law.

	Again, like the UL, if a fire was caused by non-CSA-approved
	equipment, your insurance company may not have to pay the
	claim.

	Note: strictly speaking, there usually is a legal way around
	the lack of a CSA sticker.  In some cases (eg: Ontario), a
	local hydro inspection prior to purchase, or prior to use, is
	acceptable.  The hydro inspector will affix a "hydro sticker"
	to the unit, which is as good as CSA approval.  But it costs
	money - last I knew, $75 per unit inspected.

	ULC (Underwriters Laboratory of Canada) is an independent
	organization that, amongst other things, undertakes the
	quarterly inspection of manufacturer's to ensure continued
	compliance of UL Listed/Recognized products to Agency reports
	and safety standards. This work is done under contract to UL
	Inc (Follow-up Services Division). They are not a branch or
	subsidiary of UL.

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

Someone wrote this:
"Don't bother asking in Quebec - DIY wiring is banned throughout
the province."

The statement above is not true.
You can do anything you want as long as you follow the electrical code... just like in any other province.
Not following the code may not technically make you unsafe in the real world, but it may nullify you insurance claims if your house burns down because of your sloppy work. If you're not sure, get an expert to sign off on it. ;-)
