Blackburn SP4DL – Frequently Asked Questions
1) What is the Blackburn SP4DL service post connector actually used for?
The SP4DL is a mechanical grounding connector, a service post style double connector used to terminate and bond conductors at a service entrance ground point. It is a mechanical (set screw style) connection rather than an exothermic or compression termination, so it can be installed with hand tools and re-tensioned later.
2) Is the Blackburn SP4DL UL listed for grounding use?
Yes. The SP4DL carries UL file E9809, which is the listing an inspector or spec writer will look for on a grounding and bonding connector.
3) What material is the Blackburn SP4DL made of, and will it corrode against copper conductors?
Bronze. A bronze body is the usual choice for direct contact with copper grounding electrode conductors because the two metals sit close together galvanically, which is why bronze connectors are the standard on service entrance and ground rod terminations.
4) What part number should I put on a purchase order for the Blackburn service post double connector?
Order it as Blackburn SP4DL. That is the manufacturer part number, and the connector is offered as a single model with no finish or size options to specify.
5) Does the Blackburn SP4DL come with any insulating cover or boot?
No. The SP4DL is a bare, uninsulated connector with no insulation material on it. If the installation calls for a cover or boot over the termination, that has to be ordered separately.
6) Is the Blackburn SP4DL sold individually or in a box quantity?
It ships each. The selling unit is a single connector, so a job needing one per service point is ordered piece by piece rather than by carton.
7) Where is the Blackburn SP4DL manufactured? I need country of origin for a government job.
Mexico. That is the stated country of origin for the SP4DL, which is what a public agency or federal contract submittal will ask for on a Buy American or trade compliance form.
