Difference between Final temperature and Fusion temperature of copper in earthing calculations

[ayadbasha]

Hi,

Can any body tell difference between final temperature and fusion temperature of copper (1083 C), and which has to be considered while calculating earth conductor size.

The final temperature of the grounding wire depends on connection type. See attached list.

If the strength of hard drawn copper is required for mechanical reasons, then it may be prudent not to exceed 250°C to prevent annealing of the conductors.
