Sendes vanligvis innen 7-15 dager
GN 2 is of interest to all those who are involved with specifying installing or testing electrical installations and it covers some of the most essential parts of BS 7671. The market includes consulting engineers, electricians, electrical installers, inspectors and technicians and can also serve as a guide for surveyors. GN 2 Isolation and Switching is an essential guide and reference manual on this sometimes confusing aspect of BS 7671 (The IET Wiring Regulations), the national standard to which all domestic and industrial wiring must conform. The Guide has been revised to align with the 17th Edition Amendment No 1.
