[QUOTE="Sidewinder, post: 392500, member: 9512"] OK, Central switching systems part 1. BS4163 requires that student areas in schools and similar establishments which have machinery have a central emergency switching system which shuts all machinery and power points down, and is under staff control. There is no requirement for such a system ANYWHERE ELSE. Not in factories, not in woodworking workshops not anywhere, unless BS4163 is deemed to apply. The central switching system should not apply to staff only areas, such as prep rooms. We'll come to the dc braking bit later. Then the PL of the systems. [/QUOTE]
