3M 7100004537 – Frequently Asked Questions

1) Is 3M Scotch 77 arc proofing tape adhesive, and how do I secure it once it's wrapped?
Scotch 77 is a non-adhesive tape, so it will not stick to itself or to the cable. You wrap it around the cable and then hold it in place with a glass cloth banding tape over the top. Plan on ordering that banding separately, because the roll of 77 on its own will not stay put.
2) What does the intumescent backing on Scotch 77 actually do in a cable fault?
The backing is an intumescent elastomer: under the heat of an arc or fire it expands into a thick char layer that insulates the cable underneath. The point is to keep a fault in one cable from taking out the cables next to it in a tray, duct bank or manhole. It is also self-extinguishing.
3) Is 3M Scotch 77 arc proofing tape UL Listed, and does it meet any utility spec?
It is UL Listed and RoHS 2011/65/EU compliant, and it meets Consolidated Edison Co. Test EO-5343-14. If your utility or spec section calls out the Con Edison arc proofing test, this one qualifies.
4) What widths does the 3M Scotch 77 arc proofing tape come in, and which one should I use?
Two widths: 1-1/2 in (MPN 7100004537) and 3 in (MPN 7100004701). Both are 20 ft long per roll. The 1-1/2 in is easier to conform around smaller diameter cable and into splice areas; the 3 in covers larger feeders and long straight runs faster with fewer laps.
5) How much cable will one roll of Scotch 77 arc proofing tape cover?
Each roll is 20 ft (6 m) of tape, not 20 ft of finished cable run. Arc proofing is applied in a half-lapped wrap, so the covered length is roughly half the tape length divided by the number of wraps the cable circumference takes. For estimating a job, count on well under 20 ft of coverage per roll. Rolls ship one per carton, ten rolls per case.
6) Can Scotch 77 arc proofing tape be used outdoors or in a wet manhole?
It is UV-resistant, so exposed outdoor runs are within its scope. The rated minimum operating temperature is 0 C, which matters more for cold-weather application than for service: below freezing the elastomer stiffens and will not conform cleanly, so wrap it warm.
7) Where is 3M Scotch arc proofing tape 77 made?
Country of origin is the United States, which is the answer a government or institutional buyer needs when a domestic-preference clause is in the purchase order.
