content: I am designing a "large" cabinet with DIN Rail terminal block, as follows:http://catalog.weidmueller.com/procat/Product.jsp;jsessionid=B7EB1AE85E2BEFEA79CDF22F7054D5DD?productId=(%5b1010000000%5d)&page=ProductI am looking for similar terminal block with one input and 2-5 output connections. Just stuffing 4 wires in one output isn't good enough!Any suggestions?

content: Using the central screw and a commoning bus bar not usable? You can use stacked connectors and then use a jumper to connect the various levels then.

They're usually longer and you cut them to suitehttp://catalog.weidmueller.com/procat/Group.jsp;jsessionid=B7EB1AE85E2BEFEA79CDF22F7054D5DD?groupId=(%22group3879286088418%22)&page=Group

content: Most manufacturers have a 2-in 2-out terminal in their range. Double-entry ferrules can also help keep things tidy

content: I've just found these for the terminal blocks I want to use. Don't think the safety guy will like the "push-fit" action, though. To be fair he doesn't like a lot.http://uk.rs-online.com/web/p/din-rail-terminal-accessories/2681645/

content: I'm going to be doing something fairly simple: I have an IEC socket and 6x480W(48V) PSUs. The following box will take common up all of the live, neutrals and grounds in a fairly safe way on the DIN rail:-http://www.hammondmfg.com/pdf/1554G.pdf

content: I think the commoning strips you linked might not fit. They are Z-series and your terminals are W-series.I think these are the ones you want. Check carefully in the weidmuller catalogue though.http://uk.rs-online.com/web/p/din-rail-terminal-accessories/0425320/Also don't forget your end plates to go between your different commoned sections and end brackets to keep everything from sliding about.http://uk.rs-online.com/web/p/din-rail-terminal-accessories/0425308/http://uk.rs-online.com/web/p/din-rail-terminal-accessories/3354754/

content: Also, are the 6x480W PSUs being powered from the IEC connector?6x480W is 2880W2880/230v = 12.5AIEC connector is only rated for 10Asomething to think about... unless I've misunderstood what you're doing.Perhaps an IEC 60309 16a plug would be better?
