Blackburn ICS77-1 – Frequently Asked Questions
1) Can the Blackburn ICS77-1 insulated sleeve be used to splice aluminum to copper conductors?
Yes. The ICS77-1 complies with ANSI C119.4 when properly installed on aluminum-to-aluminum or aluminum-to-copper conductors, so it handles both same-metal and mixed aluminum/copper service entrance splices. It is also RUS accepted, which matters on rural utility and co-op work where that acceptance is specified.
2) Is the ICS77-1 a crimp splice or a mechanical set-screw connector?
It is a compression splice, so it is installed with a die-type crimping tool, not a screw. There are no set screws or bolts to torque and no re-entry once it is crimped. If you need a connector you can install with a hand wrench or take apart later, choose a mechanical set-screw service entrance connector instead.
3) Does the ICS77-1 need separate tape or heat shrink over the splice?
No. The sleeve is supplied insulated, so the insulating cover is part of the connector and you are not building it up with tape or shrink tube after the crimp. That is the difference between the ICS77-1 and a bare compression sleeve of the same style.
4) How many conductors does the ICS77-1 service entrance sleeve join?
Two. It is a two-conductor splice, one conductor entering each end of the sleeve, for straight in-line service entrance runs. For tapping a third conductor off a run you need a tap connector or a multi-port device, not this sleeve.
5) How long is the ICS77-1 sleeve, and will it fit inside a meter socket or service entrance enclosure?
The ICS77-1 is a 2-25/32 inch splice. Measure the clear space in the meter socket, pull box, or gutter and allow for that length plus conductor bending room; in a tight enclosure the crimp tool head is usually the limiting factor rather than the sleeve itself.
6) Is the Blackburn ICS77-1 sold individually or in a bag of multiples?
It is sold each, so quantity one is one insulated splice. Count two per single-phase service splice point plus the neutral if you are splicing all conductors, and order accordingly.
7) Where is the Blackburn ICS77-1 made? I have domestic-sourcing paperwork to fill out.
Country of origin is Mexico. That is the detail institutional and government procurement typically needs for Buy America or trade-agreement documentation on an electrical submittal.
