“Don’t use electrical tape to hold wires together like I do”

Well, if electrical tape is holding stuff together, that's the first thing I wouldn't let happen to me!

If your using tape to hold wires together, that is your first mistake. Use a solid length of wire or solder it together. Do it right the first time to avoid problems like you encountered.

Electrical tape is not designed to hold wires together! They should be soldered, screwed to a terminal strip or fastened some other way - ANY other way other than electrical tape!

at least use wire nuts to join the wires.

WOW Seaboard, my guess is that you won't be doing that again. Electrical tape has one purpose - TO INSULATE.  If you must splice two wire together and you don't feel comfortable soldering, use this splice then you can insulate it with electrical tape such as Scotch 33.

Wirenuts, terminal strips, and a soldering iron are a model railroader’s best friends...

Hey it worked just fine for the past 9 years.Besides I am not that good when it comes to soldering.

Now the diagrams you have here.Is how I had the wires together.I then had tape around them.

Believe me I am taking notes.

O.K. point taken.

Hey it held together for a very long time.And I thought that was what electrical tape was for.After all it is called electrical tape.

What I did was twine the wires together.Then put the tape around them.I am thinking about clamps.

What do you use duct tape for ?

I’m sure a lot of us have opened shells to see 2 or 3 PCB’s sandwiched and taped together.  Remove the tape and all the residue from the adhesive left on the board.  I don’t know if it is electrically conductive.  If yes, I could see possibility of carrying voltage across the solder traces.  If not conductive, great.  But the point is that the holding ability of the tape adhesive degrades over time and has the consistency of sticky glue or maple syrup.  I use wire ties if I can.  Solder or wire nut connections.  Tape is the last thing I use.

When you got a splice like this put shrink-wrap around it and apply heat to it. (A hair dryer will do for a heat gun...). Much, much better than tape!

Duct tape is for HVAC ducts.

Wire wrapping as shown above is a prelude to  soldering.

If you do not feel you can solder go check out some model RR soldering You Tubes.  Consider searching OGR archives.

I have used wire nuts for many years, including in RVs. I have never had a wire nut connection fail, even with the vibration and pounding of highway use. Simple, cheap, quick.

Lately I have become a fan of heat shrink tubing for insulating wires vs electrical tape as I have found over time electrical tape looses its sticky ness and fails to hold. I still solder wires together, but before I solder the wires together I slip on a section of heat shrink tubing to one of the ends of wire, twist them together, solder the twisted joint and then slip the tubing over the joint and finally apply heat gently and evenly over the tubing to make a nice secure neat connection.

3M "suitcase" connectors are an easy, convenient and solderless way to securely join two wire ends. These do not require stripping.

Great suggestions from all the folks here. I have used almost all of these methods at one time or another. I have even twisted wires together and taped them. I have also used the telecom splice that Wild Mary posted. For a more permanent setup and even most temporary ones, I have an assortment of wire nuts and telco crush connectors. I save solder for certain track connections and for creating electronic controls like relays.

I really recommend you invest in a quality soldering iron and learn to use it.  You'll save yourself countless hours of annoyance.

I use the Hakko FX-888D

I have used wire nuts on the entire layout....been working for a decade now.  I can make quick changes if needed, add feeds, etc.  Works like a charm!

I thought similar to electrical tape I had heard that "duct" tape is really mislabeled in terms of appropriate use.

Aren't we supposed to use metal foil tape for ducts, as opposed to "duct" tape?

Or is that urban legend?  The ducts in my basement all used foil tape (by the builders - around 12 years ago).

-Dave

Wago lever nuts are great too, and reuseable.

Really any kind of mechanical connection will do. Twisting, nutting, soldering are all good. I happen to like crimp on butt splices and other crimp connectors.

The only thing electrical tape is good for is insulation of bare wires. I also use ten colors of electrical tape for marking, according to the resistor color code, color symbol for number.

I don't believe their was foil tape back in the day. So they used duct tape. Foil tape is better to use now that you have that choice. There are even better products out now too. The old duct tape would fall apart early if in a hot zone like an attic.

I prefer wire nuts if the joint needs to be serviceable. I have seen wire nut joints fail. I use pliers to twist the solid copper wires together first, then add the wire nut just to hold that joint.

I don't like crimp where if not done just right, the wires can arc or not carry higher amp loads. When I use crimp on stranded wires, I usually solder them once every things completed. I've had wires slip out of crimp joints too many times. Probably better tools out there to do that job. I just don't have them.

I can't apply the right amount of pressure to squeeze them fully closed I guess?

 I also don't use the stab in ports on fixtures where possible. I prefer using wire nuts and sending a single wire to the outlet or switch's screw terminal.

Joe...if one uses a slightly smaller sized wire nut than recommended for a particular size wire, and then twist very tightly, there should never be a problem.  Keep in mind, I am talking about for inside layouts.  An outside situation with the wild swings in temperature is a different situation....even so....we have a very extensive outdoor landscape lighting system and all of the connections are mechanical....been in for 15 years now and no problems....(fingers crossed)

Heat shrink or liquid tape after solder, wire nuts for testing. However electrical tape is almost useless outside the bedroom.          j

Another option, FWIW, I solder where possible, if not, crimp using this tool.  No failures.

Well I have to think about it.I am kind of not sure about soldering.See I have tried that once and it did not turn out well.I do not know maybe I did not get the right soldering iron.

Well at least I know I came to the right place.Lots of good ideas here.So I like to thank every body for the helpful ideas.

this control panel operated reliably for more than a decade ...

there is a single mounted relay i had to use to control power for a transition track and with solder tabs they were the only soldered connections  i needed to make.  all the rest of the connections are crimp and screw connections.

cheers...gary

Hmmm, If you look in the upper left corner of the photo...   It is ratcheting, and the jaws are interchangeable for different wire sizes if you choose.

^^^  i wasn't questioning your tool if that's how it sounded... mine is just another similar type.

*sigh*... good timing on the page break.... lol

I use wire nuts a lot, but not always.  It all depends upon type of connection.  My soldering connections all get heat shrink, and some mechanical twist connections also.  With wire nuts, a practice from being in heavy construction, after the wire nut is secure, I wrap with Scotch electrical tape.  This ensures even with a tug or pull on the line in question, the wire nut and connection stays secure.
