Blackburn SP8DL – Frequently Asked Questions
1) What wire sizes does the Blackburn SP8DL service post connector take?
The SP8DL is a double-conductor service post rated 4/0 through 2 AWG stranded and 4/0 through 1 AWG solid, so it handles the large service entrance and grounding electrode conductors on residential and light commercial service work. Two conductors land in the post, which is where the DBL in the model designation comes from.
2) Is the Blackburn SP8DL UL listed for grounding?
Yes. The SP8DL service post carries UL file E9809 as a mechanical grounding device, which is what an inspector looks for on a grounding or bonding connector used at the service.
3) Can I use one SP8DL to land two grounding conductors instead of two separate lugs?
That is what it is built for. The SP8DL is the double version of the service post, taking two conductors in the 4/0 to 2 AWG stranded or 4/0 to 1 AWG solid range in a single body. For a single conductor you want the single-port service post rather than the DBL.
4) Is the SP8DL made of bronze, and will it be OK on copper service conductors?
The conductor body is bronze, which is the standard material pairing for copper conductors in grounding and bonding work. Bronze on copper avoids the dissimilar-metal corrosion you get pairing copper with a plain steel or aluminum-only device.
5) Does the SP8DL come insulated or with a cover?
No insulation. The SP8DL is a bare mechanical connector, so if the installation needs the splice covered you have to add insulating tape, a boot, or an enclosure separately.
6) Is the Blackburn SP8DL sold individually or in a bag of multiples?
Sold each. Order quantity equals the number of posts you get, which matters when you are pulling parts for a multi-meter service or a panel change-out.
7) Where is the Blackburn SP8DL manufactured?
Manufactured in Mexico. That is the country of origin on record for the SP8DL service post, which is the figure procurement groups need for domestic-content or trade documentation.
