Blackburn SP4SS – Frequently Asked Questions
1) What is the Blackburn SP4SS service post made of, and can it be used on copper service conductors?
Bronze is the conductor material on the SP4SS, so it is compatible with copper conductors without the dissimilar-metal concerns you get pairing copper to plain steel hardware. Bronze bodies are the normal choice for copper service and grounding electrode conductor terminations.
2) Is the SP4SS an insulated connector or a bare mechanical lug?
It is a bare mechanical grounding device, not an insulated one, and no insulating cover or boot is part of it. If the installation needs the connection insulated or shielded, you have to provide that separately or choose an insulated-type connector instead.
3) Does the SP4SS require a crimp tool to install?
No. It's a mechanical connector, so the conductor is captured under a setscrew or clamping screw and torqued with a hand tool. There is no compression die or hydraulic crimper involved, which is why service posts like this are common on service and meter work where a crimp tool isn't on the truck.
4) Is the Blackburn SP4SS sold individually or in a box of multiples?
Each. One SP4SS ships per unit, so you can order the exact count for a panel or meter bank rather than buying a full carton. The manufacturer part number to reference is SP4SS.
5) Where is the Blackburn SP4SS manufactured? I have a country-of-origin requirement on the job.
The SP4SS is made in Mexico. If your project carries a domestic-sourcing clause, that origin is what you would submit, so confirm it against the spec section before you commit the material.
