Blackburn ATL7502 750 AL TP COMP LUG 2HL 1/2INBOLT

The ATL7502 is sized for 750 kcmil cable. It is a single-conductor aluminum compression lug, so the barrel is built for one 750 kcmil run, not a doubled pair of smaller conductors. If your feeder is a different size, you need a different lug in the series - a 750 barrel crimped onto undersized cable will not make a reliable connection.

Yes. The ATL7502 is a two-hole pad drilled for 1/2 inch bolts, so it lands on 1/2 inch studs or a bar drilled for 1/2 inch hardware. Two-hole pads resist rotation under torque and vibration, which is why they are specified on switchgear and transformer terminations rather than single-hole tongues. Bolts, washers and Belleville hardware are not part of the lug.

The ATL7502 body is aluminum and the lug is cataloged as an aluminum lug for 750 kcmil cable. Aluminum compression lugs of this style are commonly dual-rated AL/CU, but the rating that governs your install is the one stamped on the barrel - read it before crimping onto copper. Match the die to the marking on the lug, not to a generic 750 die chart.

A compression lug like the ATL7502 is crimped on with a hydraulic tool and the correct die, which gives a permanent, torque-free connection that will not loosen or need re-torquing. A mechanical set-screw lug installs with a hex key and no special tooling, which is why crews reach for it on field changes and small panels. On 750 kcmil service conductors where you want a one-time termination and minimum maintenance, compression is the usual call - just make sure you have the hydraulic crimper and 750 die on site before you strip the cable.

The ATL7502 is a tin-plated aluminum compression lug for 750 kcmil. The plating is what lets an aluminum barrel land against a copper or plated bus pad without the bare aluminum-to-copper contact that drives galvanic corrosion at the joint. Use an approved oxide inhibitor on the conductor per the lug instructions.

Blackburn ATL7502 sells each, so you order one lug per termination. On a three-phase 750 kcmil service with a neutral and a ground you are counting one lug per conductor per end - pad both ends of the run into your count before you place the order.

Country of origin is Mexico. That matters on public and federally funded work where domestic-sourcing language appears in the spec, so check the project requirement before you commit this part on a government or institutional bid.
