And since 1953, all ARRI lights have all been produced in Stephanskirchen, a small town near Rosenheim in southern Germany. Each of the cores (except the earth) is covered in a layer of colour coded PVC insulation to allow identification, these cores are then covered in an outer layer of PVC known as the sheath.Since 1924, ARRI has been developing and manufacturing professional lighting products for the motion picture and television industry.

The cable consists of 4 cores with 1 being the neutral and the other three potentially being live depending on the way the lighting circuit is designed and what position the switches are in.

Three core and earth cable: This type of cable is used for wiring two way light switches. It is important to remember that you will often see a mixture of the new and old style colour coding in commercial and industrial buildings although there should be a warning sticker as well as phase labeling. The colour of the three phase cores was changed to align it with the requirements of the European Union. Three phase and neutral cable – old colour coding The earth or earth continuity conductor (ECC) is not insulated, except for the outer sheath, and provides a path for the current to flow to ground should a fault develop. The live and neutral cores are insulated and carry the current to and from the outlet socket. The cable has three cores, a live core, a neutral core and the earth core.

Two core and earth cable: This cable connects the consumer unit (fuse box) to the power outlet sockets and carries the electricity to appliances which are plugged in to the circuit. A cable with 2.5mm 2 cores is typically used for power circuits and a cable with 1mm 2 cores is typically used for lighting circuits. It is important to remember that you will often see a mixture of the new and old style colour coding in buildings of pre-2006 construction.Ĭables come in different sizes, the size refers to the cross sectional area of the cores and this will vary depending on the amount of current flowing through them. These have been replaced with the following colours The colour of the cores was changed in March 2006 to align it with the requirements of the European Union. (A green and yellow insulating sleeve is pulled over the exposed earth core during the installation of the cable) The cores are then all surrounded by a final layer of PVC insulation, called a sheath, which is usually grey or white. Each of the cores (except the earth core in cables) are covered in a colour coded PVC insulation which provides protection and allows easy identification. The separated copper wires inside the cable/flex are referred to as cores.
