Blackburn SP9SL – Frequently Asked Questions
1) What conductor size range does the Blackburn SP9SL service post terminal accept?
The SP9SL is a single-conductor service post sized for 350 kcmil down to 1/0 stranded conductor. If your service or grounding conductor falls outside that window, this is the wrong post for the connection.
2) Can I land aluminum conductor in the Blackburn SP9SL, or is it copper only?
Copper. The SP9SL is specified with copper as the conductor material, so use it for copper runs and pick an AL9CU-rated connector if you need to terminate aluminum.
3) Is the Blackburn SP9SL a listed connector for an electrical inspection?
It carries UL file E9809 and CSA 6591, which is what an inspector looks for on a mechanical grounding connector in a service or bonding application.
4) How many conductors will the SP9SL service post take?
One. It is a single-conductor post, so each run needs its own terminal. For multiple taps at the same point you want a multi-port service post or a grounding bar instead.
5) Is the SP9SL a compression lug or a mechanical set-screw type connector?
Mechanical. The SP9SL is a mechanical grounding connector, so the conductor is clamped with a set screw and no crimp tool or die set is needed to make the termination.
6) Do Blackburn SP9SL service posts come in a multi-pack or singly?
Sold each, so order one per termination point. Worth counting your posts before the order goes in if you are landing several service conductors.
7) What is the manufacturer part number for the Blackburn 350-1/0 single service post?
Blackburn SP9SL is the part number. Country of origin is Mexico.
