Singles in Metal Conduit.

Zoomup
Mornin' All,

                       you have singles in conduit. The singles run in a horizontal plane to a B.E.S.A. box at the top of the run, and then run vertically downward for about 4+ metres. The cables have weight, and that weight causes the cables at the very top of the run to apply pressure on the insulation where the cables change direction from horizontal to vertical. What is your favourite method to prevent damage to insulation and comply with 522.8.4 and 522.8.5?


Thanks.


Z.

    From memory cables should be 'self supporting' up to 5m - so as long as any edges at the top are properly rounded off (good workmanship) I probably wouldn't feel the need to do anything special for a 4m drop.
