Which electrical tape is best? A master electrician tells you why he chooses Scotch 33+ above all the others.
By the DIY experts of The Family Handyman Magazine:September 2012
This electrical tape has stable adhesive and wraps uneven surfaces smoothly.
“A lot of electricians, including me,
swear by Scotch 33+,” says Master
Electrician Al Hildenbrand. “It’s an
amazing tape. The glue is stable
and non-gumming or running, so it
doesn’t 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,
slightly, and over
the next five to
return to its original
‘memory’ helps to
put a slight compression
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+.”
Al Hildenbrand is a licensed
Minnesota Class “A” Master
Electrician with a bachelor of science
degree in electrical engineering.
He’s the owner of Al’s Electric
Works in Minneapolis, MN.
