I’m struggling to understand the on-site guide table for Conduit factors for runs incorporating bends and long straight runs. (Table E4 amendment 3 on-site guide) - I’m out of date and need to do my 18th I know, but it isn’t something I use as a maintenance engineer.
*This is just to get my head around the work I’m having done in a garage/utility extension.
So the table only references upto 4 bends in circuits. Surely this doesn’t mean there can’t be more than 4 bends? Or so I need to put a through box in in places? Are inspection elbows classes as bends or what?!
Also if my circuit lands in the table where no value is given, I take it that it needs re designing? I.e 3M run in 20mm with more than 4 bends - No value...
I’ve seen loads of conduit runs with long runs and bends all over the show at various sites I’ve worked. Is this just rough arses doing what they want on site because no one checks their work? How do domestic elecs get around it?
An insight would be great. Cheers.
