See reader questions & answers on this topic! - Help others by sharing your knowledge The North America Free Trade Agreement came into effect on January 1st, 1994. NAFTA attempts to bring down trade barriers between Mexico, Canada and the USA. One of the "barriers" has been that of approval of material. As of January first, CSA approval of a device is legally considered equivalent to UL approval in the USA. Conversely, UL is now accepted as equivalent to CSA approval in Canada. Theoretically, this means that devices marked only with UL approval are acceptable in the CEC, and conversely CSA approval by itself of a device is accepted by the NEC. This allows much freer trade in electrical materials between the two countries. This doesn't affect the electrical codes themselves, so the differences in practice between the NEC and CEC will remain. It is also my understanding that bilateral acceptance of "approval" will only apply when the standards applied are reasonably the same. As an example, a cable approved by the NEC for a given purpose may not be acceptable by the CEC for the same purpose if the standards requirements are different. Eg: "NMD" ("non-metallic, damp") cable is usually required for residences in Canada. "NM" cable ("non-metallic, not damp locations) which is used in the same situations in the US, would probably not be acceptable in Canada. Also, municipalities can add additional requirements on top of the CEC, as they can in the US over the NEC. Thus, Canadians will probably start seeing UL-only approved materials in stores, and Americans the same regarding CSA-only. But some differences will remain. When in doubt on major items, consult an inspector. At least in Canada, the fact that the material is available in a store usually means that it's okay to install.

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.
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

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
