Blackburn SP3DL – Frequently Asked Questions
1) What wire sizes does the Blackburn SP3DL service post connector take?
The SP3DL is a double-barrel service post connector rated for 3 through 10 AWG stranded and 2 through 10 AWG solid conductors, as the product name states. Two conductor ports let you land two runs on one post instead of doubling up in a single barrel.
2) Can I use the Blackburn SP3DL with aluminum conductors?
No. The SP3DL service post is listed for copper conductors only. If your service or grounding run is aluminum, you need a connector rated AL/CU instead.
3) Is the Blackburn SP3DL a UL listed grounding connector?
Yes. The SP3DL carries UL file E9809 and CSA 6591, which is what an inspector will look for on a service grounding connection.
4) Is the SP3DL a mechanical connector or does it need a crimp tool?
It's a mechanical grounding device, so it lands conductors with setscrew pressure. No crimp tool, die set, or exothermic mold needed, and the connection can be opened and re-landed later.
5) When would I use a double service post instead of two separate grounding lugs?
A double post like the SP3DL is for landing two copper conductors at one mounting point, for example a grounding electrode conductor and a bonding jumper at the same service location. Two individual lugs would need two mounting holes and two terminations; the SP3DL keeps it on one post while staying within the 3-10 AWG stranded and 2-10 AWG solid range.
6) Does a Blackburn SP3DL come as a single piece or in a bag of multiples?
Sold each. One SP3DL service post per unit, so order quantity matches the number of posts you need on the job.
7) Where is the Blackburn SP3DL made, for jobs with country of origin reporting?
Country of origin on the SP3DL is Mexico. That's the value to put on submittal or procurement paperwork that asks for it.
