In respect to this, which side of a wall plug is positive?
In North America, looking at a wall outlet with the ground pin to the bottom, you will find the neutral conductor hole to be on the left, and it is deeper (wider pin). It would be connected to the white supply wire. The 'hot conductor' is on the right and is smaller, and would have a black or red supply wire.
Secondly, does it matter which way you plug outlet? So although flipping the plug around and inserting it backwards will probably be no problem with regard to the electrical operation of the appliance, it may create a safety hazard by exposing the "hot" half of the outlet, the half not connected to Earth, such that someone might touch it and be shocked.
Besides, which side is live on a plug?
With American and Canadian plugs, if you look directly at a socket, the ground socket will be at a bottom, the live slot is on the right and the neutral slot is on the left. If the plug is polarized, the widest slot is the neutral connector.
Which side of outlet is black wire?
We'll put the black wires on the hot side and the white wires on the left side. First connect the ground wire to the green screw at the bottom of the outlet. Wrap it around the screw and the tighten to lock the wire in place.
