Lead-free inspection on power supply (6)
I believe the answer is:
purvey
'supply' is the definition.
(I know that purvey is a more specific form of supply)
I don't understand the rest of the clue.
Can you help me to learn more?
(Other definitions for purvey that I've seen before include "Supply with provisions" , "Sell" , "Furnish" , "Provide with goods" , "Provide, supply (food)" .)
