I thought I would the stress the importance of replacing cables that have been damaged by overheating caused by bad connections or or arcing following drill damage.
Copper when heated to a high (non melting) temperature and allowed to cool naturally becomes brittle (the reverse of annealing steel)
This embrittlement will effect the mechanical strength of the copper.
