Blackburn SP4DS – Frequently Asked Questions
1) What wire sizes does the Blackburn SP4DS service post connector take?
The SP4DS is a single-conductor service post rated for 1 through 8 AWG stranded and 2 through 8 AWG solid. One conductor per post, so if you need to land more than one grounding or bonding conductor at that point you'll need a multi-conductor post or a separate connector for each run.
2) I need to land 6 AWG solid copper at a service ground point. Will the SP4DS work?
Yes. 6 AWG solid falls inside the 2 through 8 AWG solid range on the SP4DS. Stranded conductors on the same post can run heavier, up to 1 AWG.
3) What is the Blackburn SP4DS made of, and can it be used with copper grounding conductors?
The conductor-contacting body is bronze, which is the standard material pairing for copper grounding electrode and bonding conductors. It's a mechanical (bolted) connector, not compression, so it's tightened with a screw rather than crimped.
4) Does the SP4DS service post come insulated?
No insulation on this one. The SP4DS is a bare bronze service post, so if the location needs the connection covered you'll have to add tape, heat shrink, or an insulating boot yourself.
5) Is the Blackburn SP4DS sold individually or in a box?
Sold each. Order one per conductor termination point, since the post lands a single conductor.
6) Where is the Blackburn SP4DS manufactured?
It's made in Mexico. Worth noting if you're filing country-of-origin documentation on a government or institutional job.
