Posted By Topic: socket orientation

Sep 12 2017 14:20

I'm very sure I've read in 3000 somewhere that a socket must be mounted with the earth pin in the lower most position, but now I cant find it. any clues please for reference?

No such rule, since at least 1976
Having the earth contact at bottom is normal, but not required by either "3000" or "3112" (the standard for 3-pin flat-pin plugs and sockets).

The only rules for orientation in "3000" apply to mcbs etc on switchboards. "3112 requires the 'on' position of switches for sockets to be marked / indicated.

If we required all switches to be "down = on" we couldn't use 2-way or intermediate switching. And if we required sockets to be "earth down", we couldn't use a socket on a horizontal surface.

For sockets, the other consideration is avoiding strain on the flex of the plug while inserted.

I've had instances where power points were mounted so low on an office benchtop that a 10amp plug could be fitted into the socket, but not something like a phone charger.

The answer was to invert the sockets with the earth up-most.
