I am finally not an MI virgin! (feel free to take the ---- - I know its not perfect).

THIS IS A COLLEGE TEST ASSIGNMENT, BUILT TO A GIVEN DESIGN AND DIMENSIONS (I just hope they don't measure this one). CREATIVITY OR CHANGING THE DESIGN WAS NOT PERMITTED.

No, no more cables. The test instructions specify this size of hole (40mm), and the dimensions of the tray. I probably should have pointed out that this is a college test, and the MI cables are cut off where the tray ends at the top. The tutor said to leave this on the wall as an example to show the third years how neatly he wanted it doing. Or was it how not to do it? Can't remember now. ;)
 
Jesus. Never seen a hole like that in a cable tray before! Suppose its not a bad idea though, looks better than having the cables jump off the side.
 
Personally I would have kept to one side of the tray and cut the lip off the tray and swooped off. Also why did you make the double set If no more cables going on? I to have never seen a big hole in tray work like that. Not having a dig pal people just have different prefences of doing things.

To update and after reading your reply as this was a training exercise I take it that the double set was just to prove that you could manufacture this particular set? In a real scenario you wouldn't be able to fit any more cables through that hole though.
 
Because that's what his college spec told him to do.

If he'd have done it differently I'm guessing he would have lost marks.

I think it looks pretty good.

Yep that's the idea. Its all pointless and goes nowhere. :)

Its quite galling at college when you spend weeks building loads of plastic and metal trunking and conduit, wiring it all in beautifully, energising it to see if the light and two-way switching works, then the tutor takes a photo of it and says "right, rip it all off and bin it!"

You could get loads more cables through the hole - the double set is 75mm above the horizontal bit, so plenty of wiggle room. Maybe the hole isn't 40mm. Can't remember back as far as last week when I did it. And I know what you mean, we learn lots of stuff at college you would never do in the real world!
