Actually aren't most power conditioners loaded with lead?

Rodman99999, There are also galvanized grounding rods.

What for? to replace a fuse?
#2 or #3 should fit....check an AWG Wire chart.
For metric fuses? Again, check the chart.

Even scrap is getting expensive. Last year i replaced a faucted and got 11$ at a scrap yard for the one I took out.....Solid brass, Chrome plated.

Magfan,

#2 or #3 is strand wire. Cut short the strand will just fall apart.

How about a short piece of copper pipe.
3/8"
1/2"

Correct on the ground rod. Copper clad steel.

Solid round copper rod

If all you intend to do, is eliminate a fuse: solder a large gauge piece of wire across the fuse holder's terminals. Replacing a fuse, with a piece of copper, just provides two more contact points, for corrosion to form.
