A junction box that bites into the cable: eFIXX on Weidmüller's FieldPower
Electricians in the comments can't agree whether piercing straight through the insulation is clever engineering or an oversized Scotchlok.

The Vorsprung Durch Technik of Junction Boxes 🤯
What earns a junction box a title borrowed from a car advert? On eFIXX, it is a box that connects to a cable without anyone stripping it first. The short looks at Weidmüller's FieldPower system, which uses insulation displacement connection, or IDC: the contacts inside push through the cable's insulation to reach the copper. The description also asks viewers what they make of the stripping tool that appears alongside it.
"Vorsprung Durch Technik" is Audi's long-running German slogan, "progress through technology," and it is a fair nod here, since Weidmüller is a German maker of industrial connection gear. It is a step up in spectacle for a channel whose other shorts this week covered wiring a batten lamp holder the three-plate way and saving a friction-burnt cable with a splitter.
The junction box passed 300,000 views in about twenty hours. An eFIXX short usually ends its first day near 18,000, and the comment section filled up at a similar pace, reading like an argument in a site cabin. Some simply admire the engineering. Others call it the biggest Scotchlok they have ever seen, or give it vampire nicknames for the way it bites. The most liked comment asks what it really does better than cutting the cable and fitting a terminal block, unless the point is that it can be done live. Others want its current rating, ask how the contacts hold up over the years and whether it would work with steel wire armoured cable, and keep asking what it costs.
One viewer offers a cautionary tale: contractors who fitted these on conveyors without Weidmüller's own tool ended up redoing a batch of boxes and wasting cable. Earlier in the week, the channel went the other way on danger, fitting the Scame OPTIMA, a plug made for explosive environments.
