Blackburn 7020 – Frequently Asked Questions
1) What conductor size does the Blackburn 7020 stirrup bail take?
The Blackburn 7020 is sized for 2/0 solid copper conductor. It is a single fixed size, ordered as model 7020, so it will not accept stranded or other gauges reliably. If your run is a different size, you need the matching bail for that conductor.
2) Is the Blackburn 7020 bail a compression fitting or a bolted connector?
Compression. The 7020 is crimped onto the conductor with a compression tool and die, not bolted, so there is nothing to retorque later. It functions as a wire or cable compression splice connection to the stirrup.
3) Is the Blackburn 7020 tin plated copper, and does that matter for aluminum contact?
The body is copper with a tin plated finish. The tin plating is what lets the connection tolerate contact with aluminum hardware and slows surface oxidation in outdoor or damp locations, which bare copper does not do as well.
4) What is a compression stirrup bail actually used for on a grounding or tap connection?
A stirrup bail gives you a fixed loop, or bail, on the end of a conductor so a clamp or hot line hardware has something to grab instead of the bare wire. The 7020 version is crimped on as a compression splice to 2/0 solid copper, which keeps the attachment point permanent and keeps repeated clamping off the conductor itself.
5) Does the Blackburn 7020 bail come insulated or do I need to cover the connection?
No insulation is supplied on the 7020, it is a bare tin plated copper part. If the installation calls for covering the splice, plan on separate tape, a cover, or heat shrink as part of the job.
6) Is the Blackburn 7020 sold each or in a bag of multiples?
Sold each. Order one 7020 per connection you are making, so count your stirrup taps and order to that number.
7) Where is the Blackburn 7020 made?
Country of origin is Mexico. That is the detail procurement teams with domestic or trade preference language in their purchase terms need on file before release.
