Blackburn SP8SL – Frequently Asked Questions
1) Is the Blackburn SP8SL service post UL listed for grounding connections?
The SP8SL carries UL file E9809, so it is a listed grounding connector rather than a general-purpose lug. For inspectors on service equipment grounding work, that file number is the reference to cite.
2) Is the Blackburn SP8SL a single or multiple conductor service post?
Single. The SP8SL is the single-conductor version of Blackburn's service post, so it terminates one run. If you are landing multiple grounding or bonding conductors at one point, you want a multi-port service post or a grounding bar instead of stacking conductors on a single post.
3) What is the Blackburn SP8SL service post made of, and will it hold up in an outdoor meter socket or service enclosure?
The current-carrying body is bronze, which is the standard material for direct-burial and damp-location grounding and bonding connectors because it resists corrosion in contact with copper conductors. Bronze also avoids the galvanic problem you get pairing steel hardware with copper grounding electrode conductors.
4) Does the SP8SL service post come insulated, or do I need to cover it?
It is an uninsulated device. The bronze body is bare, so the connection stays exposed once made. That is normal for a grounding and bonding post, but it means you should mount it where it cannot contact ungrounded parts inside the enclosure, and keep the required clearances in a service cabinet.
5) Is the SP8SL a mechanical connector or a compression/exothermic one?
Mechanical. The SP8SL is a mechanical grounding connector, so it is made up with a setscrew or bolted clamp and needs no crimp tool, die set, or welding mold. That makes it the practical choice for field service work and for connections an inspector may want to open and check, where a compression or exothermic connection would be permanent.
6) Is the Blackburn service post sold individually or in a bag of multiples?
Sold each. One SP8SL post per unit, so order the count you need for the job rather than assuming a packaged quantity. Country of origin is Mexico if you need that for a submittal package.
