The best electrical tape

Scotch Super 33+

This electrical tape has stable adhesive and wraps uneven surfaces smoothly.

We asked our master electrician what is electrical tape used for and what’s the best electrical tape out there. Here’s what he had to say.

A lot of electricians, including me, swear by Scotch 33+, says Master Electrician Al Hildenbrand. Its an amazing tape. The glue is stable and non-gumming or running, so it doesnt leave a residue on your hands or the material if removed. But more importantly, the plastic has a stretch and return memory. When the tape is pulled off the roll, it stretches slightly, and over the next five to ten minutes, attempts to return to its original length. This memory helps to put a slight compression on a smoothly wrapped splice to hold it in place. And the stretch allows an irregular surface to be wrapped over the high spots, where the stretch is greatest, and the memory generally allows the tape on either side to snug down onto the smaller diameters. The result is a smoother, tighter and more uniform insulating of what is being covered.

There are cheaper tapes, but they seriously lack the quality of Scotch 33+.
