More sensible layout of wires (5)

I believe the answer is:

wiser

'more sensible' is the definition.
(I've seen this in another clue)

'layout of wires' is the wordplay.
'layout of' is an anagram indicator.
'wires' anagrammed gives 'WISER'.

(Other definitions for wiser that I've seen before include "More knowing" , "More judicious" , "improving taste?" , "More shrewd" , "A little more sage" .)

I've seen this clue in the Evening Standard.
