Question:

can I put a wire nut and electrical tape on a BX wire?

I am removing a buried junction box. The feed wire is still present but I don't have the new junction box ready. Can I put a wire nut on and electrical tape until I get my supplies?

Answer:

You taped the stripped ends with tape - then put in the nut over the tape? that's not a stable concept - twine nuts have a spiral steel coil interior that help make and keeping a stable electric powered connection. electric powered tape would not do this. I guess you have been making use of the two the cheap twine nuts that got here with the hot fixture, or have been making use of improperly sized twine nuts. I propose buying correct sized twine nuts and remaking the connections correct. RE added info: i could question the respected web content. First, code does not know tape as a device to make eletrical connections, in straight forward terms as a potential of insulating a splice. interior the previous days, taped connections have been soldered first to create a stable mechanical and electric powered connection; the tape replaced into for insulation in straight forward terms. We nonetheless use indexed twine connectors in the present day that require a tape overwrap for insulating purposes. 2d, jointly as taping over a twine nut isn't prohibited, the twine nut is the connecting device and can desire to bypass on the wires first, in line with all producer's guidelines.
The vinyl (PVC) electrical tape is outdoor rugged and waterproof. This would work well as a temporary junction when used in conjunction with a wire nut. It is commonly done as a temporary. Be a little generous with the tape.
yes wire nut or tape is ok for sort time if is more people a round make a sign to! install the J box and cover the box Good luck with your little project!
on the feed wire for a TEMPORARY solution a more sure connection would be a mechanical splice-either the type you slip the wires in and tighten the set screws to the wires-these can come pre-insulated or the crimp type coupling requiring a crimping tool then insulating. per code you will have to replace the entire feed line from end to end in a single piece as you can't have a splice of any kind buried unless it is in an easily accessible junction box
its fine just don't put the hot and neutral wire together also make sure that the junction box is accessible if it not then its a code violation and if you sell the house you can get sued for it.
