Are wire nuts needed?


I bought my house in July, and it was brand new. Today, I started the processes of prepping my garage for paint.

While masking off the garage door opener, I noticed the garage door sensor wires are connected (at the opener) with just tape and no wire nuts. Is this acceptable? It's an easy fix, but it kind of pisses me off that they would do that to a new house. The connections at the sensors them selves are done with wire nuts.

Thanks guys!!

Wire nuts are better. Over a long period of time the electrical tape can fall off and the connection can get dusty/dirty and fail.

The wire nut also performs the role of a clamp, by compressing the wires together for good contact. Twisting particularly of stranded wire is inferior.

Most likely the electrician ran out of wire nuts and instead of going and getting some and climbing back up the ladder, he just pulled out his roll of electrical tape.

(related) Twisting together the ground wires coming into an outlet box used to be ubiquitous but nowadays wire nuts or crimp rings are required in many cities.

Is it out of code to not use wire nuts in this application??

Maybe he soldered the connections and taped over them.

Is this 18AWG stranded wire? If so I would just use high quality butt connectors instead of wirenuts, or even better - solder and heat shrink tubing.

It is probably unfair to criticize electricians in this case. It is almost a certainty that the local AHJ does not require any type of licensed wire-man to do this work. All work associated with the garage door opener is done by the garage door company.

Sloppy yes, but "code" does not really stoop this low, or this trivial.

Your operating system for your door is a low voltage system. The NEC does not require wire nuts on these connections. Tape will get the job done. But on all low voltage connections I still like to put the wire nuts on there.

Thanks guys. I agree that it seems sloppy as hell for them to do that. It wasn't the electrician who wired the house. The garage doors are installed by a different sub. I'll go ahead and wire nut the connections. Thanks again guys.
