A household plug and socket is defined in SANS 164-1, and is essentially a modernised version of the BS 546 15 A (the essential differences are that pins can be hollowed to reduce the amount of metal used, the dimensions are metricated, and it is rated 16 A). SANS 164-3 defines a 6 A plug and socket based on the BS 546 5 A.
The flat pins measure 6.5 by 1.6 mm (0.256 by 0.063 in) and are set at 30° to the vertical at a nominal pitch of 13.7 mm (0.539 in). Australian and New Zealand wall sockets (locally often referred to as power points) almost always have switches on them for extra safety, as in the UK. An unearthed version of this plug with two angled power pins ...
IEC 60906-1 (IEC designation "Type N") [1] is an international standard designed "to provide a standard for a safe, compact and practical 16 A 250 V AC system of plugs and socket-outlets that could be accepted by many countries as their national standard, even if not in the near future."

The schematic is a line diagram, not necessarily to scale, that describes interconnection of components in a system. The main features of a schematic drawing show: A two dimensional layout with divisions that show distribution of the system between building levels, or an isometric-style layout that shows distribution of systems across ...
AS/NZS 3112 compliant plugs have two flat pins forming an inverted V-shape plus a vertical earthing pin. The flat blades measure 6.35 by 1.6 mm (1 ⁄ 4 by 1 ⁄ 16 in) with the active (line) and neutral pins 17.35 mm (11 ⁄ 16 in) long set 30° to the vertical and the vertical earth pin being 20 mm (0.787 in) in length.

Otherwise, in zone 3 and beyond, an ingress protection rating of IP20 is the minimum required. Equipment in zones 1 and 2 must be protected by a 30 mA residual current device (RCD). Shaving sockets (with isolating transformer) are permitted in zone 2 if direct spray from a shower is unlikely, even if they are only IP20.
