(ET) Ok, 400a fuse it is...

[Christopher Zach <cz alembic crystel com>]

Didn't hear back on thoughts, and given that my tractor now has an AIR 
of over 4,000 amps with the 4 strings of BB600's I figured it was time 
to buy a real fuse.

So I just ordered a 400a Class T fuse holder with a 400a JLLN fuse in 
it. The rating on the fuse is 20,000 amps at 125 volts DC, which is well 
within the range of an Elec-trak. I thought about going with a much 
cheaper ANL type fuse, but those have an AIR of only 2,700 amps max 
which as I saw years ago can lead to a very large and nasty plasma arc 
that will not. go. out.

Anyone know what the AIR is for the stock fusable link?
