Blackburn SAM 600-4 N – Frequently Asked Questions
1) What conductor size does the Blackburn SAM 600-4 N compression lug take?
The SAM 600-4 N is sized for 556.5 to 600 kcmil conductor. It is a single-barrel compression lug, so the conductor has to fall in that range; smaller feeders like 500 kcmil or 350 kcmil need a different die/barrel size in the SAM family.
2) How many bolt holes does the SAM 600-4 N lug have, and what pad pattern is it?
Four holes, on the NEMA pad pattern, which is what switchgear, breakers and bus bar drilled to NEMA spacing expect. Four-hole pads spread the current across more contact area than a one- or two-hole tongue, which is why they show up on large service and substation terminations.
3) Is the Blackburn SAM 600-4 N a bolted mechanical lug or a crimp lug?
It's a compression (crimp) lug, not a set-screw mechanical connector. You install it with a hydraulic crimp tool and the correct die, so plan on tooling at the panel. If you want a field-adjustable, screw-tightened termination instead, you want a mechanical lug rather than this one.
4) What size is the Blackburn SAM 600-4 N lug overall? I need to know if it clears inside my gear.
Overall it measures 8-1/4 by 3 inches wide. On a four-hole NEMA pad that is a long tongue, so check your bending space and phase-to-phase clearance in the cabinet before you crimp it on, especially on stacked terminations.
5) Is the SAM 600-4 N aluminum or copper, and can I land copper cable in it?
It is an aluminum compression lug. Aluminum-bodied compression connectors of this type are commonly dual rated for aluminum or copper conductor, but that rating has to be read off the connector body or the manufacturer's data before you land copper in it. What is certain from the product data is the body material and the 556.5 to 600 kcmil range.
6) What exactly do I order to get this lug, and what's the Blackburn part number?
The manufacturer part number is SAM 600-4 N from Blackburn. There is one configuration, so nothing else to specify: 556.5 to 600 kcmil, four-hole NEMA pad, compression, aluminum.
7) Is the Blackburn SAM 600-4 N sold as a pair or individually?
Sold each. For a three-phase plus neutral service termination at both ends you would be ordering per conductor end, so count your terminations rather than assuming a kit.
8) Is the Blackburn SAM 600-4 N made in the USA? We have a domestic sourcing requirement.
Country of origin on the SAM 600-4 N is the United States. For projects with domestic content language in the spec, that is the origin on record for this connector.
