Stick around a while, you'll be amazed how some in this group can overcomplicate virtually anything, with anecdotal means, overtly literal interpretations, gross misinterpretations (read as lack of reading comprehension) and general "back in the day" retrospection about years gone by!
The entertainment value is definitely worth the price of admission most of the time!
The unfortunate part is alot of good help/information gets lost in the above actions and the end result is completely misleading to a person who is asking a question with a relatively straightforward answer.[emoticon]

Oh, and welcome to the forum!

Agree, but if a person has no special crimping tools, soldering gun or heat gun a simple wire nut will be more than good.


A wire nut can work, but....

You need to be sure that the two wires are well twisted. That can be difficult if one wire is solid and the other multistranded.

You need to be sure the nut is of the appropriate size.

The wires will come out of the nut pointing in the same direction. If you need a 180 degree orientation, leave plenty of slack to avoid pulling on the wires.

For an RV subject to lots of vibration, consider using plenty of electrician's tape to secure the nut.


Maybe I should have added "done properly". YES, I already mentioned the electrical tape.

I worked with GOOD Electricians for 35 years as a Construction Superintendent so I know a bit about proper methods.

Aaaaand I rest my case....
While the OP wasn't specific about the exact application he was asking about, he was clear enough that he wasn't misrepresenting what he was asking, to be about residential/commercial building wiring. Yet, somehow, someone is still pimpin wire nuts for 12V stranded wire splices that may or may not be "indoors."


We get it. Wire nuts are what's used when you add an outlet in your bathroom...
Wire nuts are NOT the proper application for vehicle/trailer 12V wiring, in general. Yes maybe some select connections that are completely out of the weather they would be appropriate.

But while we're on the subject, what's your fave brand of wire nutz?

Are you more of an Ideal guy or do you go with the Tan Twisters? LOL

I also remember a world...(it still exists, btw), where connecting stuff on your car with wire nutz was laughable.

They're fine, and you have plenty of choices.

Also, look at WAGO 221s.

YES they meet "CODE" but IMHO they are just as bad as stab and jab receptacles. Simply put your touching a small surface to complete the circuit with these. MUCH better off with a wire nut or even a butt splice.

I built over 100 Dental Clinics in my career and I did not allow them on my jobs. Only place I did was connecting low voltage draw lighting.

wago's are rated very highly, rare to hear they are garbage. I use the ideal's and they work fine, and are considered inferior to wago.

Someone said, "I never knew connecting two wires together was so complicated." That's the problem with being a non-expert (which is what I am for sure). I often don't know what I don't know until I ask. I have learned from past misteaks -- don't assume that something that looks simple is simple.

True story -- we were taking my kids skiing for the first time and told them they would take lessons to start. My 8 year old said, "Lessons? I don't need lessons. I already know how to ski. You just put your poles between your legs and go!"

To put it another way, confidence is that wonderful feeling you have before you really understand what's happening.

So that is why I asked about how to connect two wires on my RV. My gut said "wire nuts" and my head said "maybe not -- better check with the good folks on the forum."
