Blackburn SP3SS – Frequently Asked Questions
1) What wire sizes does the Blackburn SP3SS service post lug accept?
The SP3SS single-conductor service post takes #3 through #10 stranded copper, or #2 through #10 solid. If your service or grounding conductor is larger than #2 solid or #3 stranded, this is the wrong body size and you need a larger service post.
2) Can I land two conductors in a Blackburn SP3SS?
No. The SP3SS is a single-port service post, one conductor per unit. For two runs under one connector you need a dual or multi-port service post, or a separate SP3SS for each conductor. It is sold individually.
3) What is the SP3SS body made of, and is it OK on copper conductors?
Bronze body. Bronze is the standard material for copper-only grounding and bonding connectors, so it pairs with copper service and grounding electrode conductors without a dissimilar-metal problem. It is not an insulated connector, so the connection is bare once made.
4) What does a service post connector like the Blackburn SP3SS actually do on a job?
It is a mechanical set-screw terminal used to terminate a grounding or bonding conductor at a service point, meter enclosure, or ground bus, instead of crimping. You strip the conductor, insert it, and tighten the screw, so no dies or press tooling are needed on site. The SP3SS handles one conductor in the #2 solid to #10 range.
5) What part number and origin should I record for the Blackburn SP3SS?
Order it as Blackburn SP3SS, the manufacturer part number, supplied one per unit. Country of origin is Mexico, which is the value to carry through on submittals that require it.
