I am not an electrician and know nothing about electrical tape.  I got this because I wanted to stripe a black ottoman with white tape, similar to duct tape, but just 1'' wide.  This tape worked wonderfully.  It is very easy to work with, is slightly stretchy, sticks well--so far--and was the perfect width for my project.  The base for this project is a pleather (Plastic) ottoman that my cats use as a step stool to get on the window seat.  I am anxious to see how it holds up to little paws and finger nails.  I hope it lasts because I love this ''new'' ottoman.
