In the question it states “installed on a single tier, perforated cable tray with 2 other circuits”

In the key it says you used table 40 and not 41, if the question states it’s installed with 2 other circuits do we assume it’s laid in trefoil? or am i missing something to do with perforated cable trays here?

Cheers!

As far as I understand you only ever use the trefoil table if the question specifically uses the word trefoil.
I read this as three cables layed flat touching on a perforated cable tray.
I would think this is another error in the answer key and it slipped by because the values are the same on both tables for that cable.
