An unofficial chapter of the popular Dull Men's Club.

https://dullmensclub.com/

1. Relevant commentary on your own dull life. Posts should be about your own dull, lived experience. This is our most important rule. Direct questions, random thoughts, comment baiting, advice seeking, many uses of "discuss" rarely comply with this rule.

2. Original, Fresh, Meaningful Content.

3. Avoid repetitive topics.

4. This is not a search engine or advice forum.
Use a search engine, a tradesperson, Reddit, friends, a specialist Facebook group, apps, Wikipedia, an AI chat, a reverse image search etc. to answer simple questions, identify objects or get advice. We accept very few questions, and they must be over topics much more difficult than what is easily discoverable with a search. Also see rule 1, “comment baiting”.

5. Keep it dull. If it puts us to sleep, it’s on the right track. Examples of likely not dull: jokes, gross stuff (including toes), politics, religion, royalty, illness or injury, killing things for fun, or promotional content. Feel free to post these elsewhere.

6. Not hate speech, sexism, or bullying No sexism, hate speech, degrading or excessively foul language, or other harmful language. No othering or dehumanizing of anyone or negativity towards any gender identity.

7. Proofread before posting. Use good grammar and punctuation. Avoid useless phrases. Some examples: - starting a post with "So" - starting a post with pointless phrases, like "I hope this is allowed" or “this is my first post” Only share good quality, cropped images. Do not share screenshots of images; share the original image.

8. All polls must have an "Africa, by Toto" option. Why? Because we hear the drums echoing tonight.

One suggestion. Some of the terminals are wrapped counter clockwise to the screw.

You want them to be looped in such a way that when the screw is tightened the loop is pulled into the screw instead of being pushed away from it.

You can see the way it’s wired here. Each one relative to the screw.

This was a fun watch!

I'm not knocking anything, but the half-finished tribal tattoo absolutely sold the video

Don't forget to wrap electrical tape around the edges of the units to cover up the screws. It prevents any accidental short if you happen to touch anything in the wrong way. Makes it especially safe when installing and uninstalling in the future.

I used to just put things in after wiring without a thought for the longest time. Then an old electrician taught me to do this as another added bit of safety.

.. and beautiful job ... love when things like this come together. Hope everything else works out in your project.

Oddly enough no electrical tape on twist connectors.

They should be tight enough to hold the wires together and adding electrical tape just makes it harder to see if they’re loose or coming loose.

Personally I love WAGOs for that and they’re cheap enough now.

[–] [email protected] 7 points 1 month ago (1 children)

I've never used wagos but I want to

[–] [email protected] 6 points 1 month ago (1 children)

Wago connectors are life changing. They're not as compact for large bundles, but feel ten times more safe in use.

[–] [email protected] 4 points 1 month ago (1 children)

I don't trust them compared to wire nuts. In a full box it seems too easy to accidentally lift a lever and have a loose connection.

For the same reason, push in connections really don't do it for me. If the wires can move I do not like it. Hard twists with lineman's pliers then a wire nut so tight you need pliers to remove is the only way I'm doing business. Maybe unnecessary for 2 gang boxes, but if you've got 4 or 6... I'd rather do overkill.

Only exception, the waygos are nice in ceiling fan installs when you have plenty of space and no risk of loosening.

[–] [email protected] 3 points 1 month ago (1 children)

I get that. But I can count on my missing fingers the number of times I've come across a bad connection on twist connectors. I've had zero in ten years with wagos. Anecdotal, sure. But personally I swear by them. They're worth the cost.

I agree on the push connectors though. Those are dumb.

I am not an electrician but I do try to follow code as closely as possible when I do this and all guidance I've ever read says to pigtail each receptacle or switch individually. It takes up a lot of room in the box, but if you use waygos or ideal push in connectors, it opens up a lot of room.

[–] [email protected] 4 points 1 month ago

I do love waygos, so convenient

[–] [email protected] 7 points 1 month ago (2 children)

I've never asked a pro but somewhere in my decades of DIY I got the idea that the right way to connect outlets in one box is to branch them all off the incoming wire so they're in parallel. In the photo each little metal strip between the screw terminals on each outlet is carrying all the current from all 6 sockets, which I don't think is proper.

[–] m0darn 6 points 1 month ago

I don't think it's the current in the tabs that's an issue, each socket should be rated for the full circuit's rating, but the ground shouldn't be in series, always parallel.

I'm in love with using wago lever nuts for this stuff now. Makes later maintenance so much easier, and totally avoids wire nuts. Manages to be less wire stuffing in the box too.

[–] [email protected] 5 points 1 month ago

Dude, I think you made your sandals wrong... And now you can't unsee it. You are very welcome.

[–] argh_another_username 5 points 1 month ago (7 children)

No pun intended, but why not stick the wires into the appropriate holes? Why did you choose to wrap them around the screws?

[–] [email protected] 33 points 1 month ago (1 children)

I don't like the holes. I don't trust em. With the screws I can definitely see what's going on.

I've got a bit of rewiring to do in my home soon and have been doing some research. Apparently this is called backstabbing and is generally considered lower quality work. The connection simply isn't as secure as the screw tightened half loops on the side - but if you spend all day everyday wiring receptacles it's much faster to backstab. Backstabbing is to code, but if you're wiring a few receptacles, best to take the few extra minutes to do it the more secure way.

[–] [email protected] 20 points 1 month ago (1 children)

The contact area of the terminals on the wires is much higher if you use the screws rather than the dinky little spring prongs in the stabby-holes. A small contact area means more heat is produced at the junction, which leads to premature failure, which leads to annoyance, which leads to the dark side.

[–] [email protected] 9 points 1 month ago

The only outlet I witnessed fail due to heat was backstabbed.

[–] [email protected] 11 points 1 month ago

Backstabbing is to code but really shouldn’t be. They can cause fires as the connection gets looser over time as the device is used and isn’t nearly as secure.

[–] [email protected] 12 points 1 month ago* (last edited 1 month ago)

Never use the backstabbing holes on electrical receptacles.

They come loose over time, faster if they’re not fastened properly or if the house is prone to settling.

[–] [email protected] 10 points 1 month ago (1 children)

Is THAT what the holes are for?!?

I honestly never knew.

[–] argh_another_username 7 points 1 month ago (1 children)

You press the wire directly into the round hole. To remove, you need to stick a small screwdriver into the rectangular hole next to it.

[–] [email protected] 20 points 1 month ago (4 children)

No one uses holes. They have a high fail rate, the Unless they are the high-end outlets where the screw also clamps the wire in the hole. And still, no one uses holes.

[–] [email protected] 4 points 1 month ago (2 children)

I use the holes, they're just easier. Never had one fail.

Most old work I take apart also uses the holes.

[–] [email protected] 4 points 1 month ago

Lol yeah I did in the past, too. Then I learned why they suck and why we should not use them. And to be honest with you, using the screws isn't hard. You're just being lazy.

Probably 99% of electricians will tell you to never use the back stab holes.

They don't hold well, at all, are easy to pull out when pulling an outlet/switch out, and can break the casing when trying to push the fixture in.

I don't understand how they ever got approved, they're flat out dangerous.

[–] [email protected] 4 points 1 month ago

Can’t tell which those are but

  • “back stab” where it is held by friction, common to consumer receptacles, have a poor reputation for failing. Don’t use them

  • “back clamp” (don’t remember what they’re called), common to “pro” receptacles is clamped down by tightening the screw. Much more reliable

[–] [email protected] 3 points 1 month ago

I'm not a professional electrician by any stretch of the imagination, but I have done plenty of home remodeling and I've literally never seen the backstabbing holes used. Though most of the houses I've worked on were built before ~2006

[–] [email protected] 5 points 1 month ago (3 children)

I didn't know you could daisy switches like that

[–] [email protected] 13 points 1 month ago

They're outlets

[–] [email protected] 5 points 1 month ago

You can, but the switches downstream won't work if the switches upstream are off. These are power outlets, so it's fine.

[–] [email protected] 4 points 1 month ago

Electrically sure, and I believe legally. However it’s not the best choice because you’re introducing more points of possible failure.

I wasn’t going to say anything because this is art.
