Marrettes or No ?


I know duplex receptacles are made with 2 screws on each side for wiring from plug to plug, but somebody told me that the code requires the wires (not just grounds) be marretted together and then wired to the plug instead. I'm wondering if this applies only to "push in" connections on plugs...or any connections to plugs in the "middle" of branch circuits. I'm in Canada, but I'm wondering what the code says everywhere in this respect. I also realize that local "codes" may apply. Hope my question is clear enough. Thanks!

Hey I am one of the few canadians around here.

There is no place I know of in the code book that says you can't use both screws on a plug. We do it all the time so I am sure it is fine.

There is no code requirement for this. It just standard operating procedure (SOP) to splice the wires in a "T" fashion. The "wire in", the "wire out" and the wire to the plug are spliced together in the box. Then attach the one wire to the plug. Do this for all three wires (black, white & green). This makes it easier because you only have to deal with 3 wires to get the plug installed. Using the screw terminals on the side of the plug is the recommended way.

Continuer!

One exception MiGhT be a multiwire circuit. If I remember right the continuity of the neutral in those circumstances can not depend on the device. I may be mistaken or only partway on the right track, hopefully someone who knows for sure will chime in.

Yes you have that correct.
