A container of little bits of wire (4,3)
I believe the answer is:
fuse box
'bits of wire' is the definition.
The definition suggests a singular noun which matches the answer.
'a container of little' is the wordplay.
I cannot really understand how this works, but
'container' could be 'box' (box is a kind of container) and 'box' is found in the answer.
The remaining letters 'fuse' is a valid word which might be clued in a way I don't understand.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Another definition for fuse box that I've seen is " Container for electrical safety devices".)
