Minerallac ISER30 – Frequently Asked Questions

1) What size service entrance cable does the Minerallac ISER30 staple fit?
The ISER30 is sized for #2/0 Type SE, Style SER cable, and it also takes 1 inch EMT. The opening measures 1.160 inches in diameter, so anything larger than that will not seat under the strap.
2) Is the ISER30 staple okay for outdoor service entrance runs exposed to sun and weather?
It is built for it. The molded plastic insulator is UV stabilized for severe weather, which is what keeps the gray body from chalking and cracking on a south-facing riser. Steel legs carry the fastening load, plastic keeps the steel off the cable jacket.
3) My cable is smaller than #2/0 SER. Should I still use the ISER30?
Probably not. The ISER30 opening is 1.160 inches, matched to #2/0 SER or 1 inch EMT. On a smaller cable the strap will sit loose and let the run shift. Step down to the Minerallac insulated staple sized for your actual cable diameter instead.
4) Can I use the ISER30 staple to secure 1 inch EMT conduit instead of SER cable?
Yes. The ISER30 is rated for 1 inch EMT as well as #2/0 SER cable, both falling inside its 1.160 inch diameter opening. Handy on a service riser where you are running conduit up the wall and want the same fastener for both.
5) Will the plastic on this staple cut into the SER cable jacket when I drive it?
That is what the insulation is for. The ISER30 uses a plastic injection molded body over the staple, so the cable bears against plastic rather than bare steel. The legs are high-carbon steel so they drive into wood framing without bending.
6) Will a gray insulated staple look right against my siding?
The ISER30 is silver gray, which blends against gray or weathered siding and against the cable itself better than a black or galvanized strap. For a property manager standardizing a building's exterior risers, it keeps every drop looking the same.
