Blackburn SP10SL – Frequently Asked Questions
1) What wire size range does the Blackburn SP10SL service post take?
The SP10SL is a single-conductor service post rated for 500 kcmil down to 3/0 stranded conductor. If your service or grounding conductor falls in that range, it lands in this post; anything smaller than 3/0 or larger than 500 kcmil needs a different post.
2) Is the Blackburn SP10SL for copper or aluminum conductor?
Copper. The SP10SL service post is specified with copper as the conductor material, so use it on copper service and grounding conductors rather than aluminum.
3) Is the Blackburn SP10SL UL listed for inspection sign-off?
It carries UL E9809 and CSA 6591. That covers both US and Canadian jurisdictions, which is what an electrical inspector will look for on a service grounding connection.
4) How many conductors can I terminate in an SP10SL?
One. The SP10SL is a single-position service post, so it takes a single 500 kcmil to 3/0 stranded copper conductor. If you need to land two or more conductors at the same point, use a multi-port service post or a multi-tap connector instead.
5) Is the Blackburn SP10SL a mechanical connection or does it need to be crimped?
Mechanical. It is a set-screw style grounding device, so it installs with hand tools and a torque wrench, no crimp tool or compression die required.
6) Is the SP10SL sold individually or in a box quantity?
Sold each, so you can order the exact count you need for a panel or service job rather than a full carton.
7) What is the part number and country of origin on the Blackburn service post?
Manufacturer part number SP10SL, made in Mexico. Distributors and purchasing agents matching a submittal should quote it as Blackburn SP10SL.
