Blackburn SP10DL – Frequently Asked Questions
1) What conductor range does the Blackburn SP10DL service post take?
The SP10DL is a double-conductor service post sized for 500 kcmil down to 3/0 stranded conductor, as its 500-3/0 STR designation indicates. Two conductors land in the post, so it suits service entrance and grounding electrode connections in that range. Outside 500-3/0 you need a different post size.
2) Is the Blackburn SP10DL rated for copper conductor or aluminum?
Copper. The SP10DL service post is listed with copper as the conductor material, so specify a different connector if you are landing aluminum service or grounding conductors.
3) Is the Blackburn SP10DL UL listed for an inspected service installation?
Yes. The SP10DL carries UL file E9809 and CSA 6591, which is what an electrical inspector looks for on a service post used for grounding and bonding connections.
4) What is a double service post used for versus a single-conductor lug?
A service post is a mechanical grounding connector that mounts to a surface or enclosure and lands conductors in a set-screw barrel. The double version, like the SP10DL, takes two conductors at one point, which is how you tap or splice a grounding electrode conductor or bond two large service conductors without adding a second lug and a second mounting hole. A single-barrel lug handles one conductor only.
5) Can I use the SP10DL on 4/0 or 250 kcmil conductor?
Yes. Both 4/0 and 250 kcmil fall inside the 500 kcmil to 3/0 stranded copper range the SP10DL is built for, so either lands in the post. Anything smaller than 3/0 or larger than 500 kcmil calls for a different size.
6) How is the Blackburn SP10DL sold, individually or in a box?
Each. The SP10DL service post is sold as a single piece, so order one per landing point rather than by carton.
7) What is the manufacturer part number for the Blackburn double service post 500-3/0?
Blackburn SP10DL. That is the part number to reference when matching an existing installation or specifying a double 500-3/0 stranded copper service post.
8) Where is the Blackburn SP10DL made?
Mexico. Country of origin is Mexico for the SP10DL service post, which is the figure to use on submittal and domestic-preference paperwork.
