I’ve seen a number of custom bike and car places using wago connectors for junctions in wiring up. Any views on using them for automotive use?

Both the 222 and 221 have automotive use listed as an application by Wago, rated to 32A and accept 0.2 to 4mm squared wire, so fine for most wiring applications like lighting, cdl etc. The only issue I can see is they have a max operating temp of 85 deg C. Personally, I don’t plan to use them outside the interior, and most thin wall cable is only rated to ~100 deg C anyway. 

They seem to be a neat way to junction things like tail lights, indicators, cdl etc. where you can have up to 6 outputs off a single feed.

Thoughts?

I seem to recall someone using them for a Megasquirt install a year or so ago, looked neat.

85C won't be a problem in automotive use.

Only issue I see is that you typically use stranded wire in a car, and that won't work all that well in a Wago.

the leaver type wags are designed for stranded wire, so thats not a issue. id be more worried about vibration causing a poor connection over time...

Thanks for the info.

They’re designed for stranded and single core.

i just tried the 222 series out with 1mm2, 2mm2, and 3mm2 and all fit ok and are very secure...large.ABEE0429-44B8-4926-885E-303A32BE8D17.jpeg.23f88496fb43dde8f7150616c53ebec7.jpeglarge.3353C0DC-56A3-417E-AE8E-D808EEE417B0.jpeg.f13a38210d729b1801bf7233fde0e30f.jpeglarge.E0657553-BE5F-4279-8744-0314A793BE14.jpeg.741ed19c727a6b29f9d7d4527ad71f79.jpeg

As you can see from the last pic, it clamps them evenly and securely.

You could go belt and braces and fit ferrules. I have some of these that I ordered to use in the motogadget terminal blocks...

The max that will fit with ferrules, is 1.5mm2, as you can see the 2mm2 only just fits.

Personally, from seeing how well it clamps all the wires tested, I wouldn’t worry about fitting ferrules.

I’ve ordered some 221 series blocks off Amazon today, to see how they are. They also have a fully flat back compared the 222 that have about 40% of the back angled, as you can see in pic 2. I plan to mount the connectors on the back of the fuse block etc. mounting bracket, so I suspect the 221 series will be better for this.

cheers

Steve

I’m learning too :) . I’ll see what the 221 series look like when they arrive, but so far they look like a good solution to the multiple junctions I’ll need, especially on the lighting circuits.

if you want outrage and complete disbelif that wagos could ever be any good, take a look at any of the american electrician facebook groups... "oh wagos, thats a complete hack, i would never use them, they just start fires!".   they all use wirenuts over there, you know the things that the uk banned 40 years ago....

We use Wago by the 1000's since they came out  (Electrical Contractors) and never had a problem with one.

I'd be careful about using them anywhere they might get damp. 

That would be my worry, the wires corroding over time. Even inside the vehicle.
