1m-4mm cable twin with earth

refers to an electrical cable used for wiring purposes. Here’s a breakdown of what each part of the description usually means:

1. 1m: This indicates the length of the cable, in this case, it’s 1 meter long.
2. 4mm: This indicates the cross-sectional area of the conductors within the cable. It’s a measure of the thickness of the conductive material. In this case, it’s 4 square millimeters, which is a common size for electrical cables used in various applications.
3. Twin with earth: This indicates the configuration of the cable. “Twin” refers to two conductors usually insulated and running parallel to each other, often used for typical household electrical wiring. “With earth” means there’s an additional conductor for grounding purposes. This is a safety feature in electrical systems to prevent electrical shocks and to provide a path for fault currents to safely dissipate.

So, in summary, a “1m-4mm cable twin with earth” is a 1-meter long electrical cable with two conductors, each with a cross-sectional area of 4 square millimeters, and it includes an additional conductor for grounding purposes.
