Blackburn SP1DL – Frequently Asked Questions
1) What wire sizes does the Blackburn SP1DL service post connector take?
The SP1DL is a double-conductor service post connector rated for 7-10 AWG stranded and 6-10 AWG solid wire. Both ports take conductors in that range, so it handles two runs at a single post.
2) Can I use aluminum conductor in the Blackburn SP1DL, or copper only?
Copper only. The SP1DL is built as a copper conductor device, so an aluminum service or ground conductor needs a dual-rated AL/CU connector instead.
3) Is the Blackburn SP1DL a UL listed grounding connector for inspection?
It carries UL E9809 and CSA 6591, so it satisfies an inspector looking for a listed mechanical grounding device on both sides of the border.
4) What is a service post connector like the SP1DL actually used for?
It is a mechanical grounding device that lands conductors on a service post or grounding point without crimping or exothermic welding, just torqued setscrew pressure. The SP1DL is the double version, so two conductors terminate at one post, which is what you want when a grounding electrode conductor and a bonding jumper have to share the same landing.
5) I need to land only one conductor. Is the SP1DL the wrong part?
The SP1DL is the double-port version, made to take two conductors. It will work with one, but if every post in the job lands a single conductor a single-port service post connector is the tidier and cheaper standardization.
6) Does the Blackburn SP1DL come in a pack or is it sold singly?
Sold each, one connector per unit, so order the count you need for the job rather than a bag quantity.
7) Where is the Blackburn SP1DL manufactured?
Country of origin is Mexico, which matters if you are filling out domestic-content or trade-compliance paperwork on a government or institutional job.
