Have used the low cost vinyl tapes (e.g 25 cents a roll from HF, etc) for years on 120/240 applications. Only rating on those rolls is UL5903.
Never a problem, so why use $5 a roll tape?
Obviously, if repairing an 11kV generator connection box will use only a HV specialty tape, but for 120/208, or even 277/480, has anyone ever witnessed a UL5903 rated tape failure? I've returned to some applications made over 20 years ago and still intact.
I have seen some vinyl tape wrap jobs on wire bundles in engine compartments or under cars that are coming loose, but obviously made by someone who never applied tension (or applied stikum side up), but that is a different story.
Thought I'd throw this post up as thought of the topic based on a different recent tape job post related to code compliance.
