Electrical projects require a basic understanding of the difference between indoor wires versus outdoor cables. Indoor wires are usually intended for an enclosed space like a house and come with insulation that guards against general household damage. They are largely employed in residential cables, lighting, and sundry tools where elements do not affect them. On the other hand, outdoor cables are made in a way that can survive dampness, changes in temperature, and ultraviolet rays, which makes them appropriate for external uses like flood lights and electricity supply to buildings. Using the right type of cable not only guarantees safety, but also long life and adherence to zoning laws.
