The wire colour codes are there to ensure that electricians and individuals understand what type of wire is in cables. Professional electricians work with live wires and powered cables so the different wire colours help keep the process more efficient. The electrical wiring color codes for ac and dc wires and also single phase and three phase systems are extremely important for electrical safety as well. Here at The Local Electrician our Emergency Electrician team will carry out any electrical task and know how to properly work with cabling and wiring.

What are the Wire Colour Codes?
To know what electrical cables and wires are made of, we highly encourage reading our blog with further information. What are the Wiring Colour Codes with Single and Three Phase Wiring?Single phase wiring is where two wires connect and allows an easy balance of electrical currents and loads across networks. Three phase wiring consists of three to four wires that provide a stronger electrical current. Three phase power is mostly used in places where the electrical needs are greater and can also be installed in residential places if wanted. Within the single phase wiring connection, it will contain a dual black or red live wire along with a blue neutral wire. Three phase wiring connections will have three live wires in brown, red or black and one blue neutral wire. Single phase has a voltage difference between 230V while the three phase connection has a 400V separation. Upgrading the electrical switchboard to three phase connection is recommended for adding more reliable power to the home, find out more in our blog article. Are the Wiring Colour Codes the Same Everywhere?Each country will have its own electrical code for the colour of the wires. Within Australia the live wire is brown, the neutral wire is blue and the earth wire is green and yellow. This may not be the same for every electrical system as the wire colour codes have altered throughout the years. This means that older systems might have different colours and people working on the wires need to know the colour codes for that particular time period. Below is a guide on the different wire colours for the different times:
