I remember a discussion on whether electricians twisted the conductors together or let the wire nut do the job. My question is how many of you put tape on the wire nut? I only put it on in the fixture boxes.
twist and tape?

Re: twist and tape?
MIGHT KEEP THE ELECTRONS FROM FALLING OUT. I've Seen WeatherProof boxes with wirenuts taped off Under the Assumption that it would keep the conductors and joints corrosion free, AND I'VE SEEN TOO many conductors under 1 wirenut taped for safety reasons? (Mostly motor leads) IS there Any Logical reason a good electrician would tape up a good wirenut?

Re: twist and tape?
For the life of me I can't think of a reason why someone would tape the wire nuts after they make splices. The wire nuts are not going to fall off from vibration inside the JB's
This is the best explaination I can think of !!!

Re: twist and tape?
I think this was a carry over from the days that wire nuts didn't have the metal spring in them and were made out of ceramic or bake lite. back then there was a tendency for them to vibrate off. But when I see tape on the crimp on ones then I give up as I have no clue why someone would tape a crimp on wire nut?

Or it makes you nervous about the rest of the system!

Re: twist and tape?
Lets see, you have to twist all the wires and have them hang straight down from the junction boxes and flux them. You them go from box to box with your solder ladle and dip the connections. Ya gotta remember to leave the connection in the molten solder long enough to heat up the connection or you will get a cold solder joint. Remove the ladle gently to allow the solder to for a ball on the end of the connection (that will keep it from punching through the tape when you tape it up). Tape your connections and button them up.
Oh, they don't teach it that way any more? I'll bet Bennie knows what I am talking about. BTW, it is still legal to use this method.

Hi Charlie: You have that right. I loved the old blow torch and dip pot.
It is a good policy to review the past in order to understand the present.
A trade practice was to always cut wire at a 45 degree angle. This allowed the solder to flow on the end for the purpose you stated.
The 6 inch wire length was adopted for the ease in making up the joints. The recent code change in measuring the length from the box entry point is wrong. I may go back to the pot, and want 6 inches from the front surface. :roll:
The quality of the soldered joint was easy to determine by the shiny color of the tin alloy.

Re: twist and tape?
The answer is simply to make the Electrician who works on the job afterwards learn new four letter words. As I probably can state for the rest of you it is nothing but a messy fight to get off the tape never can find the end and easily pull it off or try to slice it with a knife and not get any red dots on it.
