-grin- Thanks, John. I do see the powerful merit in your fuse-hot-only
technique. I really do. But a short of the hot side to chassis would pop the hot
fuse, not the neutral one, wouldn't it? Remember, I am using a three wire
cord with direct bonding of the chassis to my third-wire ground.
I will admit that the condition of the thrid wire grounding can be suspect in
some buildings - I've found some where the thrid pin was not connected to
anything, or was very poorly bonded to something that might be grounded somewhere
-grin-
In either case, more than one failure in a row is required to result in a
dangerous situation. As in a primary short to chassis, and the rig plugged into
a badly wired house. But that badly-wired house is just as likely to have the
hot and neutral reversed, so that under a fuse-hot-only policy inside the
rig, now the hot is riding the neutral into the rig with no fuse in line.
There are a lot of permutations, aren't there? We can only do our best to
cover as many and the most likely ones...
