Re: Going to pick up the ET on Thursday

[Seth <sethea@mediaone.net>]

If by 25,000A you mean the short circuit ability of your pile, then I
would suggest something like a bussman FWH semiconductor 200A fuse. The
voltage rating is more than you need, and maybe you can get a cheaper
fuse (but I don't know the bussman designation offhand for a 250ish volt
AC/DC fuse) with bolt holes at either end for lugged cable.
