Section load destroyed fuse (11)
I believe the answer is:
consolidate
'fuse' is the definition.
(I've seen this before)
'section load destroyed' is the wordplay.
'destroyed' is an anagram indicator.
'section'+'load'='sectionload'
'sectionload' anagrammed gives 'CONSOLIDATE'.
(Other definitions for consolidate that I've seen before include "Combine into a connected whole" , "Make stronger; combine into one" , "Join together - strengthen" , "Cement" , "Unify" .)
