It's a cable management channel hanging on the rails for the shelves, so I can move it :)
One of the most useful things I've built. A mains breaker, lots of outlets (each group fused @ 6A), a ground-fault-interrupter (that trips before my main one), a panel meter, earth jacks on the bottom for ESD stuff.
And of course, the power supplies.

This thing feeds my whole lab except the computer stuff, so when I turn it off, everything is disconnected.

Thanks a lot, that DIN rail really inspires me, going to build exactly like that.  :-+

That rail is in my shopping list now.

How do you make sure the GFI in your rail trips before the main GFI? Just using one that has a lower current at which it trips? From what I read searching forums when I was thinking about this, that using one with a lower current doesn't guarantee it will trip before the main one.

Really curious, because I could use something like that.
SeanB:
Lower trip current still is a crapshoot with a short circuit line to PE, or even line to neutral, as the energy is enough in the single cycle to trigger both to disconnect. The only benefit is that the build up of stray currents in multiple device EMC filters will trip the lower one first.

Still, like the 2 rail system, and the nice socket sets as well. U see you have pretty much the same DIN mounting power meter I have, though I put the one i have into a small 4 wide DIN box with input and output cables, using a standard SA plug and a dual IEC socket ( old PC dual IEC power lead) for a connection. for things that do not have an IEC socket i have a flying lead with a SA standard socket outlet on it, with a 15A breaker as it was a recycled industrial socket outlet that came with a 15A breaker switch.

BravoV: Be prepared for a hefty price-tag. :)
The aluminium ones are crazy expensive, and the outlets for them isn't all too cheap either.
I think my setup landed on near 500€ total.

rqsall: Yes it's a 10mA GFI and my main one is 30mA.  It probably can trip the main one, but so far it hasn't. Don't remember the specs but I believe my 10mA is faster acting then the 30mA.
I could have gone without it. It's mostly there so I don't have to set all my clocks if I screw something up. So if I trip both, it's just a minor inconvenience.
If I really need my lab to not trip the rest of the house, I'd put the GFI in the distribution box and wire that group separately.

Yeah, I have a similar reason, except with me it's not the clocks I'm worried about, but more the wrath of my son when he's in some MMORPG tournament and a probe I'm holding slips ....  :scared:
