Everywhere except for some outlets I bought from Global recently. On them the slot on the left is marked "L" and the slot on the right is marked "R". And both slots are the same size.
My house was wired such that the slot to the left of the ground connection is Neutral.
Since this involves safety, and I don't believe one should dismiss off such matters without understanding them, I ask whether anybody can explain the apparent swap on the new outlets.
An image depicting the connector with Neutral on the left can be seen at the URL below;
Thank you in advance.
The location of neutral and positive are important when using a light bulb or appliance etc. See below:
PolarizationPolarized plugs and sockets are those designed to connect only in one orientation, so the live and neutral conductors of the outlet are connected (respectively) to the live and neutral poles of the appliance. Polarization is maintained by the shape, size, or position of plug pins and socket holes to ensure that a plug fits only one way into a socket. The switch of the appliance is then put in the live wire. If the neutral wire were interrupted instead, the device would be deactivated but its internal wiring would still be live. This is a shock hazard; if the energized parts are touched, current travels to earth through the body. Devices that especially present this hazard include toasters and other appliances with exposed heating elements, which with reversed polarity can remain live even when they are cool to the touch. Screw-in light bulbs with reversed polarity may have exposed portions of the socket still energized even though the lamp is switched off. Transposition of the live and neutral wires in the wiring to sockets defeats the safety purpose of polarized sockets and plugs; a circuit tester can be used to detect swapped wires.
Unpolarized plugs and sockets are those which can connect either way around, so live and neutral wires are connected arbitrarily. Unpolarized plug/socket systems such as the Europlug rely on device construction requirements to avoid the shock hazards created by interchange of live and neutral connections
