Blackburn SP3DS – Frequently Asked Questions
1) What wire sizes does the Blackburn SP3DS service post connector take?
The SP3DS is rated for 3 to 10 AWG stranded and 2 to 10 AWG solid conductors. That covers the usual grounding electrode and bonding jumper sizes on residential and light commercial services, so a 6 AWG solid or 4 AWG stranded ground lands in it without an adapter. Anything larger than 2 AWG solid or 3 AWG stranded needs a bigger lug.
2) Is the SP3DS grounding connector UL listed?
It carries UL file E9809 and CSA 6591, which is what an inspector or a spec writer looks for on a grounding and bonding connector. Useful if you are standardizing grounding hardware across a facility and need listed devices on the submittal.
3) Can I use the Blackburn SP3DS with aluminum conductors?
The SP3DS is a copper conductor connector, so use it on copper grounding and bonding conductors. For aluminum or copper-clad aluminum terminations, pick a connector specifically rated AL/CU instead.
4) Is the Blackburn SP3DS a dual conductor connector or single?
Double. The SP3DS is a two-conductor service post connector, so you can terminate two grounding or bonding conductors at one post instead of doubling up in a single lug. That is the difference from a single-conductor service post of the same family.
5) Is the SP3DS a mechanical connector or does it need a crimp tool?
Mechanical. It is a screw-type grounding device, so it installs with a hand tool and no crimper or compression die set. That is the practical reason electricians reach for it on service and meter work over a compression lug.
6) How is the Blackburn SP3DS sold, individually or in a box?
Sold each, so order the exact count you need for the job rather than a bag quantity. The manufacturer part number to specify is SP3DS.
