Blackburn XT22 – Frequently Asked Questions
1) What conductor sizes does the Blackburn XT22 tee-tap clamp accept on the run and the tap?
The XT22 is a copper tee-tap clamp sized for a 250-500 kcmil run conductor with a 4/0 stranded tap. It handles two conductors total, one main run through the body and one secondary tap port, so it is a single-tap connector, not a multi-tap block. If your tap is larger than 4/0 or your run falls outside 250-500 kcmil, this is the wrong size clamp.
2) Can I use a copper tee-tap clamp like the Blackburn XT22 on aluminum conductors?
No. The XT22 is a copper alloy casting with silicon bronze bolts, made for copper conductors only. Tapping aluminum with a copper-only connector risks galvanic corrosion at the joint. For aluminum or mixed copper-to-aluminum work you need a connector listed AL9CU or an equivalent dual-rated mechanical connector in the matching conductor range.
3) Is the Blackburn XT22 tee-tap clamp rated for medium voltage splicing?
It carries a 35 kV voltage rating, which covers typical medium voltage distribution taps up to 35 kV class. The clamp itself ships bare with no insulation and no enclosure, so the insulation system is entirely on you: cover it with the appropriate MV tape, heat shrink, or a molded cover rated for your system voltage before energizing.
4) Does the Blackburn XT22 come with a cover or insulating boot?
No cover, no boot, no housing. The XT22 is supplied as a bare clamp with a bare surface finish, sold one each. Budget separately for insulating material and for any anti-oxidant compound your spec calls for at the connection.
5) Is the XT22 a compression connector or does it bolt on?
It is a mechanical connector, bolted rather than crimped, using silicon bronze bolts. That means no hydraulic crimp tool or dies are needed, just a torque wrench, and the tap can be opened and re-made later. If your spec requires a compression-type tap, this clamp will not satisfy it.
6) How do I order the Blackburn tee-tap clamp for a 500 kcmil run and specify the right part?
Order by the Blackburn catalog number XT22, which is the copper tee-tap clamp covering a 250-500 kcmil run with a 4/0 stranded tap. It is a single-configuration item, no finish or size options to pick, and it is sold individually, so quantity is simply one per tap point.
7) Can I use the XT22 tee-tap to land two taps off one main run?
No. The clamp has a single secondary port and accepts two conductors total, one run and one tap. For two taps off the same run conductor you need either two XT22 clamps spaced along the run or a multi-tap connector with the port count you need.
8) What is the 3/8 inch dimension on the Blackburn XT22 tee-tap clamp?
The stated outside diameter on the XT22 is 3/8 inch. Use that figure when checking clearance in a crowded pull box, manhole, or under a tap cover, since the clamp gets built up further once it is taped or shrink-covered.
