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
