Would the wire splice picture shown inside the electrical box be code?

Watch those sizes. 5/32" is pretty dang small. And the next size up is still only 6/32" ?!?! Both under 1/4" unshrunk.

Maybe for identification or something, but these cheap heat shrinks are not meant for stuff like that. Think car wiring, or hobby electronics, repairing a broken wire on some small appliance, small stuff like that. If you are doing repairs to code, i wouldn't be buying the cheapest junk you can find, like this.

Nope, that is absolutely a code violation

These aren't listed, and they don't appear to have a voltage rating.

Definitely don't use them as a means of insulation for any kind of home or commercial wiring. For the picture shown, it would be better to use a listed wire nut or WAGO. If that's AC electrical wiring in that pic, there's a bunch of code violations going on there. For my own sanity, I'm gonna just assume it's low voltage coax cable or something Big Grin

Yeah, stick to using these for labeling or just low voltage DC toys/hobby stuff and you're good.

Not really made for outdoor use. I used this in the past for trailer wiring and the shrink tube became brittle after a couple years (maybe 3 years). Midwest heat/cold

Edit: The box mine came in is a wider box, so this might be an upgraded version that can take the outdoor elements better.

Just used wago for wiring up a smoke detector, so worth the extra money as they decide to change the adapters with every new model.
