Blackburn CX 70 TN – Frequently Asked Questions
1) What wire sizes does the Blackburn CX 70 TN mechanical lug take?
The CX 70 TN accepts conductors from 14 AWG up to 4 AWG. It is a single-conductor copper mechanical lug, so anything larger than 4 AWG needs a different frame size.
2) Can I use a tin plated copper lug on aluminum conductors?
No. The CX 70 TN is a copper-bodied lug listed for copper conductors. For aluminum or a mixed AL/CU run you need a dual-rated AL9CU lug instead. The tin plating on the copper body is there for corrosion resistance and to reduce galvanic issues at the bolted pad, not to make it aluminum-rated.
3) How much current is the CX 70 TN copper lug rated for?
Rated 70 amps. Size the lug to the conductor ampacity of the circuit it terminates, not just to the wire size, since the 14-4 AWG range spans ampacities on both sides of that number.
4) Does this Blackburn lug crimp on or is it a set screw type?
Set screw. It is a mechanical lug, so the conductor is clamped under a screw and no crimp tool or die set is required. That makes it a field-terminable option when you do not have a hydraulic crimper on site.
5) Does the CX 70 TN come insulated?
No insulation. It is a bare tin plated copper body, so if the application needs covered termination you will have to add heat shrink or boot it separately.
6) Is the Blackburn CX 70 TN sold individually or in a bag of ten?
Sold each, under part number CX 70 TN. For a panel or ground bar build where you need one lug per conductor, count your terminations and order that quantity.
7) Is the Blackburn CX 70 TN made in the USA for buy-American jobs?
Country of origin is the United States, which is what federal, municipal, and institutional procurement specs usually want documented on electrical terminations.
