interior wiring - romex vs. individal runs

[orcadigital]

My connections were all wrapped in electrical tape before closing up the box to prevent them from vibrating loose. That said, the twist wire connectors are probably better, assuming that you know the proper way to do them, and can actually do them properly. Most people do not have that skill. My twist nut connections were inconsistent, and with 3+ wires, even worse. The last of my concerns for failure is these connectors frankly. Knowing many trailers wire their 12v with splice lock connectors and last for a decade and more without failure (my trailer is 9 years old and has them, fully functional, i replaced them due to the fact I was soldering in the new DC wiring anyway), and are much less reliable then the WAGO's.

I am sure that any professional would cringe at some part of most everything here. I am not sure anyone has the skills to build something that would pass the muster of a professional electrician, welder, woodworker, cabinetmaker, structural engineer, solar engineer, and all the other things we try to build into our trailers.

I would definitely avoid my thread, as it will make most professionals cringe, no matter what field they are in.

I was very impressed by the WAGO 222 with the snap locks, I think I will order some
And check them out further. Most all my stuff is wired so that there is no load unles I power it on.
I have like tons & tons & tons of breakers & disconnects - mostly due to the 3" foam insulation
If that ever would catch a spark - its good bye Charlie
whats always interesting to me on this forum
Is how many people are obsessed with quality - but yet many try to scrounge stuff together - for free if possible.
I guess that's human nature we all have

overthetop as an electrician of more than thirty years experience,the opinion that I quoted was exactly what I wanted to quote, if it however offends you that I might quote someone else, and not you, so sorry.

As a certified construction inspector for 27 years I guess we will agree to disagree about the WAGO 222

Which it appears you have never viewed, used in your job nor do you have any evidence to support your quoted other persons conclusion.
About this single product WAGO 222 connector,
this connector works great with " STRANDED" wire

Show me some evidence where this connector fails more then any other method PLEASE ??
Google it for me " failures of WAGO 222 connectors"

It also seams strange if you have 30 "PLUS" years electrical experience you need to copy another's mans opinion.

Respectfully yours

Hi Orcaditigal

First of all I don't see anything wrong with your Romex wiring and the WAGO 773 ? for solid wires....
Researching a little about WAGO's I found the Wago 222 would be an EXCELLENT connector as many here swear by stranded wire.
That standard comes from "BOATS" as they vibrate like hell & are in a wet & salty environment, if it works there - your CT is a cakewalk.
I use both solid & stranded and have had no problem with either.
However as i'm residential I have never seen the WAGO 222, they are not sold at HD or Lowes
They are actually rated from 24 - 32 amps
and WAGO makes over 25,000 different products

below are a few you tube videos to prove my point, for all those who are stuck - and drowning in misinformation,
PLEASE DROWN - by yourself, and let the other open minded folks make up their own minds after the view the FACTS !!!!

perhaps I should look at the wagos for use with stranded wire, thanks for the input over-----, however , for use with a solid wire, I personally, have little to no faith in any electrical connection on solid wire by mere means of a " sprung " steel tab that has a definite fall off of tension after thermal cycles due to either constant or intermittent amperage draw. That being said, I too am a firm believer in the use of stranded wire just for the resistance to vibration. Whether it be a boat on rough water or a 150 hp electric motor on a stone crusher. thanks again ot

Something that should be mentioned here...typical household 120v outlets, switches and fixtures (which I see frequently in conversions on this sight), etc are designed specifically for solid wire not stranded. It is against NEC code to use a stranded wire in a device designed for solid wire (romex). I understand if a person doesn't really care about the codes but they are written generally as a result of casualty. Just something to consider.

[OverTheTopCargoTrailer]

Do you happen to have that section of the NEC you are quoting handy
Because I see stranded wire JUST ABOUT EVERYWHERE
I have seen stranded wire all over, including- San Francisco - nothing is tougher then those guys !!

1. NEC does not approve devices; they approve methods. CSA, UL, ETL approve equipment.

2. NEC does specify wire sizes that must be stranded (big ones)

3. Devices are rated by their manufacturer as to suitability for stranded wire. Some receptacles I have used permit stranded wire on the side screws, but have "back stab" connections that are only suitable for solid wire. Back insert types with clamp screws are okay for stranded; at least the ones I have used were. Terminals suitable for stranded usually have clamping plates, IME. BUT I am NOT certain if that is universal.

So, in conclusion I believe the question of stranded being okay or not okay is device specific.

Would tinning the strand with some solder so it won't come apart work or would wire nuts and electrical tape be good?

Thanks for the clarification...I should have been more specific. It is a NEC requirement that the electrical device be used or wired according to its listed design.
