25mm armoured

[wellshocked]

was just wondering if this was the correct size, any help would be appreciative

a 25 mm armoured with a run of about 25 metres , ambient temputure 25degrees, clipped on its own direct to a wall.
it is feeding a supply of a 100 amp switch

someone told me it should be downgraded to a 80 amp , but i cant see whats wrong with it being as it is.

also , i been told that you have to earth cable tray, i always thought that if it was rcbo protected you wouldnt have to do it , am i wrong?


cheers

How do you connect swa securely without a gland? Does it just go through a rubber grommet like a piece of flex?
I can't see how terminating cable into the box on the unit would invalidate the warranty tbh
