I'm buying a house. The attic had a wire with frayed outer insulation. I negotiated repair of the cable. The seller has responded that the repairperson wrapped the fray with rubber electrical tape (I presume 3M tempex or a similar product). It has a continuous max temperature rating of 190 degrees farenheit. Attic temperatures here (Phoenix) reach the 180s during the summer. I have questionable faith in this repair. Is there anything in The National Electric Code that says this repair is improper?

Was this the outer jacket or the wire itself?– MachavityCommented Mar 23, 2019 at 17:25

Electrical tape is usually vinyl. Are we talking about something else?– isherwoodCommented Mar 23, 2019 at 17:33

And what sort of cable? The only type that could really fray is old fabric cloth-covered cable.– isherwoodCommented Mar 23, 2019 at 17:34

1Yeah, the electrical code has a whole section of rules for electrical wiring operating in spaces with temperatures beyond norms. I see on the web where you got "180s" that's 82-87 degrees C and it's also anecdotal, and could be more.– Harper - Reinstate MonicaCommented Mar 23, 2019 at 18:27
