Blackburn 20H-B1-5 – Frequently Asked Questions
1) What wire sizes does the Blackburn 20H-B1-5 split bolt connector take?
The 20H-B1-5 is rated for a 2/0 stranded main conductor down to 2 AWG solid on the tap side, which is what the "MAIN: 2/0 STR - 2 SOL" marking means. If your run conductor is larger than 2/0 or your tap is smaller than the 2 AWG solid limit, you need a different catalog number in the series rather than forcing this one.
2) What is the Blackburn 20H-B1-5 split bolt made of, and can I use it on copper grounding runs?
Silicon bronze alloy is the body material, which is the standard choice for copper-to-copper mechanical taps and grounding connections. Copper conductors are what it is built to join; do not use it to land aluminum.
3) Do I need to tape or insulate a split bolt connector after I make the tap?
Yes. A split bolt like the 20H-B1-5 is a bare mechanical connector, so the finished tap has to be insulated in the field with tape or a cover to rebuild the conductor insulation. Budget that material into the job; it does not come with the connector.
4) Has the Blackburn 20H-B1-5 been superseded by a newer part number?
The current replacement identifier for the 20H-B1-5 is 7TAH006000R0044. If you are matching against a purchasing system or an older submittal that lists the 20H-B1-5, that newer number is the same item.
5) Should I use a split bolt or a compression connector for a ground tap?
A split bolt such as the 20H-B1-5 is mechanical: it torques down with a wrench, needs no dies or crimp tool, and can be taken apart later if the tap changes. A compression lug or C-tap is permanent and needs a matched crimp tool. For service work, panel taps, and grounding runs where you may revisit the joint, the split bolt is the practical pick; for a buried or irreversible connection, go compression.
6) Is the Blackburn 20H-B1-5 sold individually or in a bag quantity?
It sells each. The "1 BG" in the part description refers to the single-piece bag packaging, so one order unit gets you one connector, not a box of them.
7) Where is the Blackburn 20H-B1-5 split bolt manufactured?
Country of origin is Mexico. That matters if you are filing origin documentation on a government or institutional purchase order.
