control panel power distribution

for version 2 of my brewing system, i'm trying to stay away from the high amp distribution block i use now. i'm also trying to use DIN rail mountable stuff, and came across these:

for example, plug power into the bottom of one terminal block, jumper across the top, and then feed power out the bottom of the rest. probably common knowledge to some of the people here, but for the rest of us who have no idea what we're doing, i thought i'd share.

and in case i'm completely wrong about how to use these things, i'm hopeful someone will point it out

p.d.

I was planning on doing something similar. I was looking at automationdirect.com. I'm not sure how the prices compare though. Thanks.

I looked at automation direct. They sell the same stuff, but I think it comes in bulk amounts.
