Cable Pulling and Wire Termination: Clean Runs and Reliable Connections
Most electrical failures are not in the cable, they are at the ends. Good pulling protects the conductor, and good termination is what makes a connection last decades instead of failing hot.
QUICK ANSWER
Cable pulling protects insulation with correct lubricant, tension, and bend radius, while termination makes durable connections through correct strip length, torque to spec, and the right lug for the conductor. The most common defect is an under-torqued or over-torqued lug, which creates a high-resistance joint that overheats over time.
Pulling Without Damaging the Conductor
A pull that exceeds the cable maximum tension or violates the minimum bend radius damages insulation invisibly. The fault shows up months later as a ground fault. Correct lubricant, a monitored tension, and swept bends protect the run.
Termination Is a Torque Problem
- Strip length: too short leaves a weak grip, too long leaves exposed copper.
- Torque to spec: every lug has a value, and a calibrated driver is the only way to hit it.
- Conductor match: aluminum and copper need the correct listed lug and antioxidant, or the joint corrodes and heats.
Why the Ends Matter Most
A loose or over-torqued termination is the root of most panel hot spots. This connects directly to panel and breaker work and safe voltage verification.
WE BUILD THIS IN VR — THE PRIME VR
We build terminations into VR so electricians practice strip length, lug selection, and torque-to-spec with haptic feedback that signals under and over-torque. The scoring layer catches the loose joint before it becomes a panel fire.

Why does termination torque matter so much? +
An under-torqued lug creates a loose, high-resistance joint that heats up under load. An over-torqued lug damages the conductor. Both lead to failure, so hitting the exact torque spec with a calibrated tool is critical.
What happens if I exceed cable bend radius? +
Pulling a cable tighter than its minimum bend radius stresses and can crack the insulation, creating a hidden fault that shows up later as a ground fault or short.
Can I terminate aluminum and copper the same way? +
No. Aluminum needs a listed dual-rated lug and antioxidant compound. Using a copper-only lug on aluminum causes corrosion and a failing, overheating connection.
