Frequently Asked Questions (FAQs)
1) What conductor sizes does this split bolt support?
This connector supports copper conductors from 1/0 AWG stranded (STR) to 4 AWG solid (SOL).
2) Is this connector suitable for both solid and stranded wire?
Yes. It is designed to accommodate solid, stranded, and flexible class copper conductors within the listed range.
3) What material is the split bolt made from?
The connector is manufactured from high-grade brass for strength, conductivity, and corrosion resistance.
4) Is this split bolt UL Listed?
Yes. This connector complies with UL 486A-B and ANSI C119.4 standards.
5) What temperature rating does it have?
The split bolt is rated for continuous operation up to 90°C (194°F).
6) Can this be used in outdoor environments?
Yes, when properly insulated and protected in accordance with NEC and local code requirements.
7) Does this connector provide a low-resistance electrical path?
Yes. Precision-machined threads and high clamping force help minimize resistance and maintain stable contact.
8) What tools are required for installation?
Standard electrical hand tools are typically sufficient for tightening and installation.
9) Is this connector reusable?
Reuse may be possible depending on condition, but replacement is recommended for critical or permanent installations.
10) Is this connector insulated?
No. Split bolt connectors are uninsulated and require insulation after installation if specified.
11) Can this connector be used for grounding or bonding?
Yes. It is commonly used for grounding and bonding applications where permitted by design and code.
12) How do I choose the correct split bolt size?
