Blackburn 30H – Frequently Asked Questions

1) What wire sizes does the Blackburn 30H split-bolt connector accept?
The 30H is rated for a main run of 4/0 stranded down to 2 solid conductor. That range is what decides whether it is the right body for your splice: run a conductor larger than 4/0 and the bolt will not close on it, run something smaller than 2 solid and you will not get proper compression. For a service upgrade tapping a 4/0 feeder, this is the size that fits.
2) What is the 30H split bolt made of, and will it corrode on copper conductors?
Bronze alloy body with a metallic finish. Bronze is the usual choice for copper-to-copper mechanical splices because it is galvanically close to copper, so you avoid the dissimilar-metal corrosion you get pairing copper with a plain steel fastener.
3) Do I need a crimper or special tool to install a Blackburn 30H split bolt?
No. It is a mechanical connector, so a wrench is all it takes. You seat the conductors in the split, run the nut down and torque it. No crimp die, no hydraulic tool, no heat. That is the reason crews carry split bolts for field splices and service work where dragging a crimper into the vault is not practical.
4) Should I use a split bolt like the 30H or a compression connector for a 4/0 splice?
Pick the split bolt when you need a reusable, tool-light connection and when the two conductors are different sizes, like 4/0 stranded tapping down to a 2 solid. It comes apart with a wrench if the circuit gets reworked. A compression sleeve is the choice where you want a permanent, irreversible joint and already have the dies on site. The 30H covers the mechanical side of that decision.
5) Does the 30H come insulated, or do I have to tape it?
The 30H is a bare bronze split bolt. Insulation is not part of it, so any splice made with it needs to be re-insulated in the field with tape or a split-bolt insulating cover sized to the connector, or left inside an enclosure where the connection is protected.
6) Is the Blackburn 30H sold individually or in a box?
It is sold each, one connector per unit, so you order the exact count your splice schedule calls for rather than a fixed carton.
7) What is the exact part number for the Blackburn 4/0 split bolt, and where is it made?
Order it as Blackburn 30H, which is the manufacturer part number. Production is sourced from Mexico and the United States. Useful to have on hand if you are standardizing split bolt sizes across a facility and need the number to match on a reorder.
