old electrical wiring colours to new

Old electrical wiring colours are a common and often perplexing problem for homeowners, electricians and anyone dealing with the rewiring or installation of a new electrical system. Prior to the adoption of a standardised set of electrical wiring colours in the early 1960s, all the different countries across Europe used their own specific codes for the various wires.

The UK followed suit in 1945 by introducing a British Standard for the wiring of domestic properties, which was regularly updated and amended until the switch over to a universal standard in 1961. This standard was designed to make it easier to understand the function of each wire and to reduce the risk of injury when handling these systems.

The new system utilised three core electrical wiring colours which are still used in homes today: brown, blue and green/yellow. The brown wire stands for the live power flow, while the blue wire is known as the neutral wire and the green/yellow is the earth wire. It is vitally important that the correct wiring colour is used when installing any electrical wiring, as this ensures that live circuits are kept separate from neutral ones and also from the earth wire which helps protect against short-circuits and other safety hazards.

Overall, understanding the difference between old and new electrical wiring colours makes it easier to identify the function of each wire which in turn reduces the risk of electrical fires or injuries. If you're seeking a professional opinion, we recommend speaking to a qualified electrician who can tell you which electrical wiring colours are applicable for your home and ensure that dangerous mistakes aren't made.
