Do an electrician's job (4)
I believe the answer is:
wire
'do an electrician's job' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for wire that I've seen before include "Flexible strands of metal" , "Flex" , "Thin strip of metal, may be barbed" , "Metal fastener" , "Hand signal; breaker" .)
