Arc-Proofing Electrical Tape
This 3M Scotch Series 77 tape provides arc proofing for electrical insulation tasks. The black elastomer roll measures 1-1/2 inches wide and 6-5/8 yards long with a 30 mil thickness. It is supplied as a continuous non-adhesive roll for professional use.
Suited for Arc Protection Needs
Electricians requiring arc proofing insulation on cables and splices will find this tape matches the requirement. The elastomer construction delivers the specified 30 mil barrier. Buyers who need an adhesive-backed tape for general wrapping or colour-coded identification should look at alternative products.
30 Mil Thickness Decides Fit
The 30 mil thickness is the critical specification determining whether this roll meets your insulation depth requirement. Verify that your application calls for this exact dimension before purchasing. The continuous roll format supplies the length needed for multiple jobs.

Questions about this item
Which width and length combination of this 3M Series 77 tape should I choose?
This roll is 1-1/2 inches wide and 6-5/8 yards long, giving a single continuous length for wrapping and insulation tasks.
What does the 30 mil thickness mean when I apply the tape?
At 30 mil the elastomer backing provides a heavy-duty barrier that resists abrasion and conforms tightly around cables during arc proofing work.
How does the non-adhesive elastomer construction affect installation?
Because the tape is non-adhesive, it fuses to itself when stretched and wrapped, creating a void-free seal without sticky residue on conductors.
