Electrical wiring colors coding standard (EWCS) for three phase electrical applications are standardized to assist the identification and detection of individual wire phases. Wiring color codes for Alternating current (AC) and Direct current (DC) power distribution circuits have altered on various occasions and modify depending on region.
Three Phase Electricity Supply
Circuits will use five wires:
- Earth wire
- Neutral wire
- Live wire
- Line 2 wire
- Line 3 electrical wire
International Wiring Colors Codes
The Fixed Wiring Electricity Supply (FWES) needs particular wiring color regulations (WCR-BS 7671) to classify various power lines in distinctive countries.
Wiring Codes for USA
The United States of America (USA) have their own wiring colours for electrical circuits:
- Black
- Red
- Blue
These USA’s Color Codes are used for 208 VAC three-phase.
Wiring Colors Codes for Australia
Australia also have a peculiar wiring color standard (WCS). Wiring Colors Codes for Australia are:
- Brown,
- Orange
- yellow
All above mentioned color codes for Australia are used for 480 VAC.
The United Kingdom-UK's new cable colors for plugs are now unified with Europe's power cable colors for Alternating current (AC) and Direct current (DC). Most of Europe abides by IEC ('International Electro Technical Commission') electrical wiring colors code for Alternating current (AC).
