Start from mm², not handle length alone
Ratchet cutters are sold by published maximum copper/aluminum cross-section. Handle length helps leverage but does not replace the mm² ceiling. This site maps mm² to three verified VEVOR US classes.
The ladder on this screen
Class 240 covers up to 240 mm². Class 400 covers up to 400 mm². Class 500 covers up to 500 mm² (about 1000 MCM aluminum on the linked listing). Example: 120 → 240; 300 → 400; 450 → 500; 600 → NO_MATCH.
Soft copper and aluminum only
These consumer ratchets are not for steel wire, ACSR, armored cable, or finely stranded welding cable. Copper capacity on a listing can be lower than aluminum — confirm the live page.
Jaws, PPE, and de-energize
Keep fingers clear of the ratchet mechanism. Wear PPE. Cut only de-energized conductors. Ratings are manufacturer claims — verify the live listing. Affiliate tracking is pending.
