Colour code

Wednesday, May 15, 2013 | Labels: code, colour | | To enable cords to be easily and safely identified, all typical wiring security specifications objective a program for the efficiency on power conductors. In a typical power code, some shade development is necessary, while some may be recommended. Many local guidelines and exceptions exist. Older set ups differ in shade specifications, and shades may move with efficiency heat visibility, light, and aging.

To enable wires to be easily and safely identified, all common wiring safety codes mandate a colour scheme for the insulation on power conductors. In a typical electrical code, some colour coding is mandatory, while some may be optional. Many local rules and exceptions exist. Older installations vary in colour codes, and colours may shift with insulation exposure to heat, light, and ageing. Many electrical codes now recognize (or even require) the use of wire covered with green insulation, additionally marked with a prominent yellow stripe, for safety grounding (earthing) connections. This growing international standard was adopted for its distinctive appearance, to reduce the likelihood of dangerous confusion of safety grounding wires with other electrical functions, especially by persons affected by red-green colour blindness

Many power specifications now recognize (or even require) the use of wire protected with natural efficiency, additionally recognizable with a popular yellow red red stripe, for security grounding (earthing) connections. This growing globally standard was applied for its unique appearance, to reduce the chance of dangerous uncertainty of security grounding cords with other power features, especially by individuals affected by red-green shade loss of vision.
