I'm currently in isolation due to covid, so I can't go out to get electrical tape.

My keyboard's sustain pedal wires (~1 mm diameter) got cut, so I was planning on splicing them (no solder) and using duct tape for structural and electrical security after. Is this okay?

  • Alternatively, I also have thick, black gorilla tape.

    Can't you order some electrical tape online? Mar 31, 2020 at 3:40

    On low-voltage wiring, it's fine for a MacGyver. If mains wiring was involved, that's not acceptable, but if you're servicing mains wiring you surely own the correct tape. Mar 31, 2020 at 4:34
  • Got it, thanks Harper.

  • Note also that some duct tapes are conductive when damp. I would not use duct tape for anything electrical.

Low voltage lets you get away with all sorts of things ;^)

Why? - Because they won't burn your house down.

Any sort of (non-conductive) tape is fine - use what you have, without misinterpreting that in silly ways if you happen to have a roll of aluminum foil tape... Duct .vs. gorilla is pretty much "gray or black" in this case - does not matter. Clear packing or office tape would also work. Masking tape would work for a while, then dry up and fall off in the middle of your Carnegie Hall performance.

If your isolation tool arsenal includes a hot glue gun, you can make a neater and more durable fix (I rebuilt a LOT of laptop power cord plugs "better than new" back in the day with hot glue and popsicle stick to replace the "custom molded plastic" at the end of the job. I did solder those, but they were carrying more power than your keyboard sustain pedal wire.)
