Blackburn SP9SS – Frequently Asked Questions
1) What wire range does the Blackburn SP9SS service post take?
The SP9SS is a single-conductor service post rated for 350 kcmil down to 1/0 stranded conductor. One run of cable per post, so if you need to land two conductors you need a dual-port post instead.
2) Can I land aluminum service entrance cable in a Blackburn SP9SS post?
No. The SP9SS conductor material is listed as copper, so it is a copper-only connector. For aluminum or AL/CU service conductors you need a dual-rated connector; putting aluminum in a copper-only lug is a code and corrosion problem.
3) Is the Blackburn SP9SS UL listed for service equipment grounding work?
It carries UL E9809 and CSA 6591 file listings, which covers it for use in both US and Canadian installations. That matters on inspected commercial service work where the AHJ wants a listed connector on the grounding electrode and service conductors.
4) What is the difference between the short and standard length service post?
SP9SS is the short-body version. The short post occupies less vertical space on the bus or panel pad, which is what you want in a crowded meter socket or shallow service enclosure where a full-height post won't clear the cover. Electrically it handles the same single 350-1/0 stranded copper run.
5) Is a service post like the Blackburn SP9SS a mechanical or compression connection?
Mechanical. The SP9SS is a mechanical grounding device, so it lands the conductor with a set screw rather than a hydraulic crimp. No dies or crimp tool needed, which is why maintenance crews favor them for service and grounding terminations that may be re-torqued or re-pulled later.
6) Do I need a separate post for each service conductor?
Yes with this one. SP9SS is a single-port service post, one conductor per unit. Dual and multi-port service posts exist for landing several runs on a single base, but the SP9SS is not one of them.
7) Does the Blackburn SP9SS come in a multipack or is it sold individually?
Sold each. One post per order line, so count your conductor terminations and order that quantity; a three-phase plus neutral job means four posts, not one package.
8) Where is the Blackburn SP9SS service post made?
Manufactured in Mexico. Relevant if you are bidding federal or state work with domestic-sourcing language in the spec, since it would not satisfy a Buy American clause.
