Keeping a record of your wiring is essential to make future fault finding easier. It should let you know what each wire does and where it goes. Cable makers are used for the clear labelling of all wires and cables.
We have various products listed for the easy cable identification listed that will help keep wiring organised. There are clip on coloured and plain markers plus a range of coloured self adhesive labels that can be written on using most pens and markers. There are also cable ties with markers that can be used.
