Have you ever seen any of these in the field?

I have installed and serviced a large number of disconnects and have never seen one designer for bottom feed.

I think 404-6(C) discusses this, not line and load per say, but that the breaker terminals to the load must be de energized with the breaker in the open position. That is probably why the line in terminated where it is, by design of the breaker.

Trekkie, in a feed through breaker the terminals to the load would be deenergized if the other end terminals were fed from the source, this would be regardless of which end terminals were used.

Here , here , here , and here are some answers to this from SQ D

Bob,
Yes, but only the bolted pressure design and normally only in switchboard construction.

This is the first link I have found: http://ecatalog.squared.com/techlib/docdetail.cfm?oid=090089268008ba19

Also try a Google search for "boltswitch inverted".

Roger, you are correct. I was looking at the section, and it made sense at the time, but as soon as I read your post I realized I was in error.:O
