• a designated series of female sockets, each having a casing,
• a main cable connecting said main plug to a first one of said female installation sockets in the series,
• a corresponding designated series of (a) male serial plugs and (b) male socket box plugs, each of said male serial plugs and male socket box plugs having a respective set of male plug pins,
• each said female socket including (a) a serial set of plug pin contacts for receiving said plug pins of a corresponding said male serial plugs, (b) a socket box set of plug pin contacts for receiving said plug pins of a corresponding said male socket box plug, the plug pin contacts of said male serial set being electrically connected within the casing of the female socket to the plug pin contacts of the mail socket box set,
• an associated said male serial plug and male socket box plug being connected in pairs to an associated said female socket, and (a) each said male serial plug having a serial cable connected thereto, and (b) each said male socket box plug having a socket box cable connected thereto, and
• each said serial cable being connected to a following said female socket in the series and each said socket box cable being connected to a respective socket box having at least two sockets into which power utilizing equipment can be plugged,
• a corresponding designated series of predetermined patterns of ribs and grooves formed correspondingly on the male serial plugs, on the male socket box plugs, and on the female sockets, said patterns restricting that (a) each corresponding male serial plug and (b) each corresponding male socket box plug are only connected to a corresponding female socket in the designated series.

An installation for supplying power to a multiplicity of socket boxes, the installation comprising:

• a main plug for connecting to a source of electrical power,
• a designated series of first, second and third female sockets, each said female socket having a casing,
• a main cable connecting said main plug to said first female socket,
