An alternative to SY or steel conduit would be FP200 or equivalent. That has a full 100% screen in intimate contact with the CPC (you'd need 3 core+E if you still wanted to run your clean earth, and the cable would be screened using the 'dirty' earth of the CPC, but you'd be way down into diminishing returns by that point.09 May 2008 02:40 PM 09 May 2008 02:40 PM mickyboro Posts: 8 Joined: 25 April 2006 I'm after the CSA Of steel conduit if us IET Forums CSA tables for steel conduit Top : Bottom Top : Bottom 09 May 2008 04:22 PM 09 May 2008 04:22 PM rocknroll Posts: 9677 Joined: 03 October IET Forums CSA tables for steel conduit 16mm pipe used as cpc: light gauge=47mm IET Forums CSA tables for steel conduit

5 second disconnection times - IET Engineering Communities

Hi all Something that I have always wondered about since I started doing electrical work. The 0.4 and 5 second disconnection times. 0.4 makes sense as it is quick. However 5 seconds still seems a long time for exposed conductive parts to remain live. When I first started, lighting circuits had a 5s time.
