Blackburn 20SBC-B1-5 – Frequently Asked Questions
1) What wire sizes does the Blackburn 20SBC-B1-5 split bolt take?
The Blackburn 20SBC-B1-5 is rated for stranded copper conductors from 2 AWG stranded up to 2/0 AWG stranded. Both the run and the tap have to fall inside that range for the connector to seat properly on the threads.
2) Can I use this split bolt on aluminum conductors?
No. The 20SBC-B1-5 is a copper-bodied split bolt sized for copper conductors, so it should be kept to copper-to-copper connections. For aluminum or mixed copper/aluminum runs you want a connector specifically listed AL9CU, not a straight copper split bolt.
3) Can I connect two different wire sizes with the 20SBC-B1-5, like a 2/0 run to a 2 AWG tap?
Yes, that is the normal use for this size. The 20SBC-B1-5 spans 2 AWG stranded through 2/0 AWG stranded, so any combination of run and tap within that window works. If the tap is smaller than 2 AWG, step down to a smaller split bolt instead of overtightening this one.
4) Is a split bolt an acceptable way to splice grounding electrode conductor or a tap in a junction box?
A split bolt like the 20SBC-B1-5 is a mechanical connector, the type commonly used for straight splices and tap connections on copper conductors. It is tightened with a wrench, no crimp tool or die set needed, which is why it gets used for field splices and bonding taps. Insulate the finished connection with tape or a split-bolt cover, since the body itself is bare copper.
5) Does the Blackburn 20SBC-B1-5 come with an insulating cover?
No, it ships as a bare copper split bolt, sold individually. The insulation is a separate item, either a snap-on split-bolt cover sized for this connector or standard rubber and vinyl tape built back to the conductor insulation level.
6) Do I need a crimp tool for the Blackburn 20SBC-B1-5?
No tooling beyond a wrench. It is a mechanical split-bolt connector, so the conductors are laid in the bolt slot and the nut is run down to clamp them. That is a practical advantage over a compression lug or C-tap when you are working in a pull box without a hydraulic crimper on site.
7) Is the 20SBC-B1-5 sold individually or in a box of connectors?
Each. The selling unit on the Blackburn 20SBC-B1-5 is a single connector, so quantity you order is the number of splices you can make.
8) Where is the Blackburn 20SBC-B1-5 split bolt made?
India. Country of origin on the 20SBC-B1-5 is India, which matters on jobs carrying domestic-sourcing or Buy American requirements.
