How to read cable cross-section and voltage ratings
Cross-section and voltage markings are the language of cable trade. Teaching distributor teams to read them reduces wrong picks from the warehouse.
mm² and ampacity
Cross-section in mm² drives current-carrying capacity, but installation method and ambient temperature also matter. Do not sell “by mm² alone” without design context for large projects.
Multi-core markings must be read carefully—total copper and per-core size are easy to confuse on invoices.
Voltage rating
Common ratings such as 0.6/1 kV appear on power cables. Using a cable below the required rating is a safety and compliance failure.
Print rating expectations on your internal pick lists so warehouse staff verify sheath print before dispatch.
Training tip
Keep a one-page legend near the cable racks. New staff make fewer mistakes when markings are decoded the same way every time.
NMF product pages list clear titles—use them when training remote sales teams.
