Does anyone have any thoughts on the best way to terminate an SWA into the new style flush CUs such as Hager's, BG's etc.? I ask as all seem to either employ oval or square knockouts, which is great for the surface boards when using truncking etc. but no great if you are trying to comply with Reg 522.6.204 and 522.6.204 where your tails would effectively be inside a wall / burried less than 50mm from the surface.
So far the best but not really ideal solution I have come with for top or bottom entry (to overcome what seems like a design flaw to myself) is that you would need to terminate the armoured cable into something like a galvanised adaptable box that you mount hard up aginst the bottom of the CU oval / sqaure entry to get the SWAs cores safely into the CU (using gromet / gromet strip on all edges etc.). I know the Hager board has a round KO on the left and right hand side but this would causes an issue in most cases in terms of space to allow for the cable bend. You then have issues with your cables falling outside of prescribed zones as you are likely to want to route them verticle up or down in the wall once out of the CU.
So intrested to know what others think would be a good solution or thoughts from anyone who has had to fit any of these newer flush units.
