Blackburn SP5DS – Frequently Asked Questions
1) What conductor sizes does the Blackburn SP5DS service post connector take?
The SP5DS is rated for 1/0 through 2 AWG conductors, and it accepts either stranded or solid wire in that range. If your grounding electrode conductor or service neutral falls outside 1/0 to 2 AWG, you need a different post size rather than forcing the lug.
2) Can I land two conductors in the Blackburn SP5DS, or just one?
It is a double service post, so it takes two conductors, each within the 1/0 to 2 AWG range. That is what makes it useful in a service enclosure where a grounding electrode conductor and a bonding jumper both have to terminate at the same point instead of doubling up in a single-barrel lug.
3) Is the Blackburn SP5DS UL listed for grounding use?
Yes. The SP5DS carries UL file E9809 as a mechanical grounding device, which is what an inspector will look for on a service or grounding electrode termination.
4) What is the Blackburn SP5DS made of, and will it hold up in a damp service enclosure or meter socket?
The current-carrying body is bronze. Bronze is the standard material for direct-burial-rated and service-entrance grounding connectors because it resists corrosion and is compatible with copper conductors. For aluminum conductors, use a connector specifically rated AL/CU rather than assuming this one is.
5) Does the Blackburn SP5DS come insulated or with a cover?
No insulation. The SP5DS is a bare mechanical connector, which is normal for a grounding post inside a panel, meter socket, or service enclosure. If you need an insulated termination for an ungrounded conductor, this is the wrong part.
6) Is the Blackburn SP5DS sold individually or in a multi-pack?
Sold each. One SP5DS double service post per unit, so order one per termination point you need to make.
7) Where is the Blackburn SP5DS manufactured?
Mexico. That matters on public and federally funded jobs where country of origin has to be documented on the submittal.
