Blackburn SP9DL – Frequently Asked Questions
1) What conductor size range does the Blackburn SP9DL service post take?
The SP9DL is a double-conductor service post sized for 350 kcmil down to 1/0 stranded conductor, so it accepts two runs anywhere in that range. If your service or grounding electrode conductor falls outside 350-1/0, this is the wrong post for it.
2) Is the Blackburn SP9DL rated for copper conductor only, or can I use aluminum?
Copper is the conductor material specified for the SP9DL. Use it on copper service and grounding conductors; for aluminum or dual-rated AL9CU applications you need a connector listed for aluminum.
3) Does the Blackburn SP9DL carry a UL listing for inspection sign-off?
It does. The SP9DL is covered under UL E9809 and CSA 6591, which is what an inspector or a spec on a grounding and bonding submittal is looking for on a mechanical service post.
4) Can one SP9DL service post land two conductors instead of running two separate connectors?
Yes, that is the point of the DL (double) configuration. One SP9DL post terminates two conductors in the 350-1/0 stranded range, so you can bring two runs into a single mechanical termination rather than mounting two single posts.
5) Is the Blackburn SP9DL a mechanical or compression connector?
Mechanical. It is a set-screw style grounding device, so it installs with hand tools and a torque wrench rather than a hydraulic crimper and dies. Compression lugs are the alternative when you want a permanent, non-reusable termination.
6) Where is the Blackburn SP9DL made? I have a country-of-origin requirement on my submittal.
The SP9DL is manufactured in Mexico. If your project carries a domestic-sourcing clause, that origin will need to be reviewed against it before the submittal goes in.
