What is the warranty period?

We provide a 12-month warranty from the date of purchase. Any quality issues caused by manufacturing defects will be covered by free replacement.

What materials are used in the lug?

The lug features a bimetal construction with a high-conductivity copper palm (often tin-plated) and an aluminum alloy barrel for compatibility with aluminum conductors.

How should the lug be installed?

Strip and clean the aluminum conductor, apply neutral conductive grease if required, crimp using the correct die size, and mount onto the breaker terminal screw with recommended torque.
