Cable lug selection guide: barrel, palm, material and plating
Most termination failures are chosen before the crimp tool arrives. A four-part method for selecting a lug that fits the cable and the terminal.

Lugs and terminals
Most termination failures start before the crimp tool is picked. These guides cover lug and terminal selection, bimetallic joints, crimp quality, plating and the tests that prove a joint will hold.

Cable lugs for switchgear and panel builders: space, torque and inspection
The lug that works on the bench can fail in the panel. How to select for access, stud patterns, clamping and the inspection the assembly actually needs.

Cable lugs for transformers and UPS
Duty current is only the start. Fault withstand, terminal pads, clamp force and clearance decide the lug on a transformer or UPS connection.

Connector housing materials and flammability
UL 94, glow wire, CTI and temperature index answer four different questions. A housing that passes one can still fail the others, so the specification has to ask for all four.

Crimp die selection and pull-out strength
The die and the barrel are one system. How to match them, set the crimp height and use pull tests to prove the joint rather than assume it.

Braid for earthing and grounding
An earth braid has to carry a fault current for a short time and then survive years of corrosion. Sizing, joints and testing all matter more than the weave.
