Blackburn CTG250 – Frequently Asked Questions

1) What conductor sizes does the Blackburn CTG250 ground clamp accept?
The CTG250 is built for the No. 2 through 250 kcmil range, which is where its model designation comes from. That covers most grounding electrode conductors and equipment bonding jumpers on commercial service work. If your conductor is smaller than No. 2 or larger than 250 kcmil, you need a different clamp in the family.
2) Can I use the Blackburn CTG250 on aluminum conductor?
Yes. The CTG250 is specified with aluminum as the conductor material it is made for, so aluminum grounding and bonding conductors in the No. 2 to 250 range land in it directly.
3) Does the CTG250 ground clamp need a crimper or special tool to install?
No. It is a mechanical connector, so it lands the conductor under a bolt or setscrew with hand tools. No dies, no hydraulic crimper, no exothermic mold. That is the practical difference between this and a compression or cadweld connection: it can be installed and later re-terminated by any electrician on site.
4) Should I use a mechanical ground clamp like the CTG250 or a compression connector?
Pick mechanical where the connection has to be accessible and reworkable, which is most panel, service entrance, and equipment bonding work. The CTG250 bolts up with ordinary tools and can be opened again if the conductor changes. Compression and exothermic connections are the choice for buried or permanently concealed grounding where nobody will ever service the joint.
5) Is the Blackburn CTG250 insulated?
No insulation. The CTG250 is a bare mechanical ground clamp, so if the installation calls for a covered or insulated connection you would need to insulate it in the field or select a different device.
6) What part number do I quote for the Blackburn No2-250 mechanical ground clamp?
Blackburn CTG250 is the manufacturer part number, and it is a single-model item, so there are no finish or size suffixes to add. UPC 783786126583.
7) Where in a building is the CTG250 ground clamp typically used?
Service entrance grounding, panel ground connections, equipment bonding, and industrial equipment grounding are the common uses, and it shows up in residential, commercial, and industrial installs alike. For an MRO or facilities group standardizing one clamp across a site, the No. 2 to 250 range covers most of what you will land.
