They further protect their property by the installation of security measures such as locks and/or alarm systems. In the same way, electrical systems need: 1. to be protected against mechanical damage, the effects of the environment and electrical overcurrents; and 2. to be installed in such a fashion that persons and/or livestock are protected from the dangers that such an electrical installation may create.

The IEE Regulations recommend five ways of minimizing this danger: 1. g. cable insulation. 2. By placing the live part or parts behind a barrier or inside an enclosure providing protection to at least IPXXB or IP2X. In most cases, during the life of an installation it becomes necessary to open an enclosure or remove a barrier. g. by using a screwdriver to open a junction box.

0 mm2. 0 mm2 if not. However, if these bonding conductors are connected to exposed conductive parts, they must be the same size as the cpc connected to the exposed conductive part, once again subject to the minimum sizes mentioned. 0 mm2 as the minimum size. 6. Do I have to bond free-standing metal cabinets, screens, workbenches, etc.?
