Is wrapping frayed electrical wiring in duct tape safe?

Duct tape is for sealing (no laughing now) ducts. Yes, air conditioning and heat ventilation ducts. They seal duct leaks and seams against air. Sometimes they have some aluminum in them (hence the silver color) because its more airtight than fabric. Electrical tape is made for use on electrical stuff (again, surprise!). read more

Probably safe, but won’t pass inspection. Electrical tape would be better. Wiring is made of three important parts - a conductor, to conduct the electrical current, and insulation, to prevent short circuits and to protect people from touching the conductor, and a strain relief to provide mechanical strength. read more

Duct tape is okay but is very temporary. Electrical tape should be used as it will insulate the wiring and you won't get a shock. You need to replace the flex/able as soon as possible, because the tape may move or fray. read more

Start at the end that is away from the electrical connector. Start wrapping the tape around the wire in a clockwise motion. As you finish each segment, smooth out the tape with your hands. Continue to do this for the length of the wire. read more
