Blackburn SP2SL – Frequently Asked Questions
1) What wire sizes does the Blackburn SP2SL service post connector take?
The SP2SL is a single-conductor service post connector rated for 5 through 10 AWG stranded and 4 through 10 AWG solid. One conductor per post, so if you need to land two separate grounding or bonding conductors you want a two-conductor post instead.
2) Is the Blackburn SP2SL UL listed for grounding use?
It carries UL E9809 and CSA 6591 file listings, so it is acceptable on both US and Canadian installations as a mechanical grounding connector.
3) Can I use the SP2SL with aluminum conductor?
The SP2SL is specified with copper as the conductor material, so size and use it for copper grounding and bonding conductors in the 4-10 AWG range. For aluminum or dual-rated AL9CU service, choose a connector specifically marked for aluminum.
4) Will the SP2SL land a 6 AWG grounding electrode conductor?
Yes. 6 AWG falls inside both stated ranges, 5 through 10 stranded and 4 through 10 solid, so a 6 AWG copper GEC lands in this post either way it is made up. A 2 AWG or larger conductor is outside the range and needs a bigger lug.
5) What is a service post connector used for on a panel or meter socket?
A service post connector like the Blackburn SP2SL is a mechanical lug that mounts on a grounding or neutral post in service equipment and clamps the conductor under a setscrew. It is the mechanical alternative to an exothermic or compression connection, so it can be loosened and re-terminated if the conductor is resized later.
6) Is the Blackburn SP2SL sold individually or in a bag quantity?
It sells each, one connector per unit, so an order quantity of 10 gets you 10 posts. Useful when you are counting terminations against a panel schedule rather than buying by the box.
7) Where is the Blackburn SP2SL made?
Manufactured in Mexico. That matters on public and institutional work where country of origin has to be documented for procurement.
