Blackburn C5C – Frequently Asked Questions
1) What die size does the Blackburn C5C insulating cover fit?
The C5C is sized for O-die compression connections up to 1-3/4. It is an input/output connector cover, so it slips over the completed crimp to insulate it rather than being part of the connection itself.
2) Does the C5C come with the connector, or do I order the compression connector separately?
The C5C is the insulating cover only. The compression lug or splice it goes over is a separate item, so a complete job needs both the connector sized to your conductor and this cover sized to the O-die crimp.
3) What size is the Blackburn C5C cover, and will it clear inside a tight enclosure?
Net dimensions are 3.75 x 1.6 x 1.25 inches. Lay that against the free space around the crimp in your box or cabinet before you commit, since the cover adds bulk over the finished connection in all three directions.
4) What is the Blackburn C5C connector cover made of?
Molded polypropylene, in black. Polypropylene is the standard insulating shell material for compression connector covers, so it handles handling and pulling into a box without cracking the way a brittle shell would.
5) What part number should I put on a purchase order for the Blackburn O-die connector cover?
Order it as Blackburn C5C. That is the manufacturer part number for the black polypropylene insulating cover for O-die crimps up to 1-3/4.
6) Is the Blackburn C5C sold individually or in a bag?
Sold each. Order one per connection you need to insulate, so count your crimps on the panel or splice box and order to that number.
7) Where is the Blackburn C5C made?
Canada. That matters if you are buying for a government or institutional job with country-of-origin reporting on the submittal.
