Household wiring does not usually use three-phase supplies and the clash only occurs in three-phase systems. Wiring to the old standard can be detected by use of a red wire. The new standard colour code does not use red. Where new wiring is mixed with old, cables must be clearly marked to prevent interchange of phase and neutral.

A full-sized to-scale wiring diagram can be made of a cable harness. This wiring diagram can then be laid on a peg board and used to guide the construction of more cable harnesses. Harnesses can be inserted into their equipment as an assembly. Cable harnesses that are reused many times, like automobile wiring harnesses, are created with ...
Three-phase transformer with four-wire output for 208Y/120 volt service: one wire for neutral, others for A, B and C phases. Three-phase electric power (abbreviated 3ϕ [1]) is a common type of alternating current (AC) used in electricity generation, transmission, and distribution. [2]
An automotive wiring diagram, showing useful information such as crimp connection locations and wire colors. These details may not be so easily found on a more schematic drawing. A wiring diagram is a simplified conventional pictorial representation of an electrical circuit. It shows the components of the circuit as simplified shapes, and the ...

But for a 2-wire system derived from a 3-wire distribution network, as in the case of a normal residential supply, the 2-wire installation standard specified red and black, with black for the earthed side of the supply and red for the "live" side, regardless of whether the house was fed from the positive or negative side of the 3-wire system.
