Hi,

I have a crabtree patress box for an architrave switch and one end is
marked "top". Is there any reason it has to have this end at the top?
I ask because the top only has one cable entry; the bottom has two and
I would like to drop two cables through the top. Is there a reason I
can't install it upside down?

TIA

There's no obvious reason why the manufacturer elected to print "top" on
the architrave patress. You can mount it either way up, unless Crebtree
live in a strange universe where you can only mount the switch one way
up relative to the patress.

Basically, if you can mount the switch either way (which I expect you
can) then you can mount the patress either way.
