Here in NZ,
The term switch-board is used to denote the device which gives most control over an installation.
This is for Domestic Installations only,
anything installed downstream for this is deemed to be a Sub-main.
In Commercial and Industrial installations, there is one Main Switch-board and everything installed downstream from that, is deemed to be a Distribution Board.
Plug-tops here with a Back-entry facility are called Tap-on's.
We call a receptacle a Socket Outlet and these range from 5A to 32A in a Domestic place, to 300A in an Industrial Plant. [Linked Image]
