Blackburn 250 T 250 – Frequently Asked Questions

1) What conductor sizes does the Blackburn 250 T 250 tee connector take on the main and the tap?
The 250 T 250 is sized for 250 kcmil on the run (main) and 250 kcmil on the tap, which is what the model designation spells out. It is a copper compression tee, so both the main and the tap barrels are crimped with a die tool rather than bolted. If your tap conductor is a different size than the run, you need a different main/tap combination in the series, not this one.
2) Does this Blackburn copper tee connector come insulated, or do I have to tape and cover it myself?
Bare copper, no insulation on the connector itself. Insulation material is listed as none, so the installer has to re-insulate the finished joint, typically with a cold shrink or heat shrink tube or an insulating cover rated for the circuit voltage. Budget for that cover as a separate line on the job.
3) Can I use this tee connector on aluminum service entrance conductors?
No. It is a copper connector, tin-plated, and copper compression connectors are made for copper conductors. For aluminum or for a mixed copper-to-aluminum splice you need a connector marked AL9CU or an aluminum-bodied compression tee. Putting copper hardware on aluminum conductors risks a galvanic and thermal problem at the joint.
4) Is this a tee tap connector or a straight inline splice?
It is a tee, three conductor openings total: the service conductor passes through the main barrel and the tap conductor lands in the perpendicular leg. If you only need to join two conductors end to end, use a straight compression splice or sleeve instead.
5) Do I get one connector or a bag of them when I order the Blackburn 250 T 250?
Sold each, one tee per unit. On a three-phase service tap you will normally need three (or four with a neutral tap), so order per conductor, not per splice point.
6) Is this Blackburn tee connector made in the USA for a government or public works spec?
Country of origin is the United States, which is what a Buy American or domestic-preference line on a public project usually turns on. The order-of-magnitude detail your submittal will also want is the crimp die and tool, since a compression connector has to be installed with the manufacturer's specified die.
7) What does the tin plating on this copper compression tee actually do for me?
The tin plate on the copper barrel slows oxidation of the contact surface, which matters in damp locations like handholes, pedestals, and underground pull boxes where a bare copper joint can corrode over time. It does not change the conductor size range or the crimp procedure.
