Blackburn SP8DS – Frequently Asked Questions
1) What wire sizes does the Blackburn SP8DS service post connector take?
The SP8DS takes 4/0 through 2 AWG stranded conductor, or 4/0 through 1 AWG solid, in a single port. Anything smaller than 2 AWG stranded or 1 AWG solid falls outside that range, so a smaller service or grounding electrode conductor needs a different post.
2) Is the SP8DS rated for copper only or can I land aluminum in it?
Copper is the conductor material specified for the SP8DS. Don't use it as an aluminum or dual-rated AL/CU connection point; for aluminum service or bonding conductors, source a connector marked AL9CU.
3) Is the Blackburn SP8DS UL listed for use on a service ground?
It carries UL file E9809 and CSA 6591, so it will pass inspection as a listed mechanical grounding connector. Keep it to the listed wire range and conductor material on the label when you make the termination.
4) How many conductors does the SP8DS service post hold?
One. The SP8DS is a single-port service post, so it gives you a single mechanical termination point. If you need to land multiple grounding or bonding conductors at the same post, use a multi-port ground bar or multiple posts instead of doubling up in a single-conductor port.
5) What is a service post connector actually used for on a panel or meter socket?
It's a mechanical grounding device: a post that mounts in an enclosure such as a meter socket, load center, or service panel and gives you a screw-down landing point for the grounding electrode or bonding conductor. The SP8DS is the single-conductor version sized for large service-entrance copper, 4/0 down to 2 AWG stranded.
6) Is the SP8DS sold individually or in a bag?
Each. The SP8DS ships as a single piece, so order one per termination point you're making.
7) What is the exact part number and country of origin for the Blackburn service post?
Blackburn SP8DS is the manufacturer part number, made in Mexico. That's the number to quote for a submittal or to match an existing post already installed in a panel.
