Knowledge Element: Electrical and low voltage wiring
Definition of Knowledge Element:
Know how to carry out the mains electrical and low voltage wiring associated with a job.
A very brief summary of the Knowledge:
Cable routes should be planned carefully to ensure the safety of the cables, the safety of the building and the safety of the building occupants. Make sure that cables travelling together are not likely to suffer electrical interference from other cables. Also make sure that regulations with regard to cables and other services are adhered to.
