Especially if you're constantly shuffling wires around or are in a hurry. Under ideal assembly conditions where you technician is very practiced, etc. I'm certain this is a very rare occurrence. But conditions in FIRST pits are far from ideal, and our student technicians will not be terribly well practiced next year. So wire ferrules are the answer. They crimp onto the ends of stripped, stranded wire, turning it into a solid piece of wire that won't birdcage on you. Pin terminals are a similar option, using a standard ratcheting crimper.
Probably I'm being completely paranoid, but having my students use ferrules will give me just a little more peace of mind. |
I am 98% sure that the Wagos on the PD are not designed to accept ferrules.
I am 100% sure that the Wagos on the PD are not designed to accept tinned wires. Tinning the wires will result in a very poor connection.
Simply strip the wires and insert. The cage-clamp works best when it can push the strands a bit to grip multiple surfaces. Using a ferrule reduces the contact area.
