Re: More than one power distribution board
I think we managed to break one WAGO connector once.
To the OP: why would you want a second board? Have you run out of breaker slots or something? |

Re: More than one power distribution board
The only thing specialized about the official Wago tool is the slippery coating that makes it a tiny bit easier to use than a standard small screwdriver. I typically use the kind that's often given away as a promotional item. (We're actually using a ground-down right-angle Allen wrench on our PDB this year because of a specific spacing issue in the robot.)
What does "intuitive" mean? Push the tool into the slot and the connector opens up. Pull it back out and the connector closes. I suppose you could break something if you got silly and tried to turn the handle while it was inserted, or if you tried to pry the plastic apart with it, but neither of those seem like an obvious thing to do. |

Re: More than one power distribution board
I'm not sure what the per-unit cost targets are, but I tend to use electronic overcurrent circuits. They've gotten remarkably capable and reasonably-priced in recent years. They're also amazingly compact.
I would also like to see an Ethernet switch integrated onto the power distribution board, with 12v and GND going to each pair of magnetic center taps. Then you could use a Ubiquiti Pico- or Nanostation and an Axis PoE-capable camera and get rid of a whole class of wires. |

We use one small (3mm) for the PDB and a jewelers for the tiny ones for the cRIO and bumpers. Insert tool, flex retaining clip, insert wire, remove tool. This hasn't broken our connectors or bumpers or boards in the 5 years we've been using it. I don't think intuition is really a metric you should be caring about here - nothing we use is intuitive. Screwdrivers for some are not intuitive. Your iphone may be more intuitive for some of your students than a screw driver. |

"Just do it" is a recipe for broken hearts and broken hardware. It fosters creativity and learning, absolutely, but at the cost of safety and time/money/resources. |
Re: More than one power distribution board
Everyone,
One of the biggest errors in terminating to the WAGO connectors is improper stripping of the insulation. WAGO recommends 5/8" to insure good contact inside the terminal. If you do that, and insert the wire so no copper is showing, then you have a good contact with the wire and it will not pull out. Please remember that these terminals are used in production environments and industrial installations. Installers rarely will insert the tool fully, they simply have learned the "feel" of inserting the tool, lifting while inserting the wire and then dropping the tool to lock the wire. While it takes two handed coordination, an experienced installer will take about 1 second for each termination. |
