For safety we recommend Finolex Flamegard FR-LSH or Finoultra wire, which limit flame spread and give off far less smoke in a fire, with Legrand protection: DX3 MCBs sized to the wire, a 30 mA Legrand RCCB on the incomer, and Legrand shuttered sockets. Above all, buy genuine: a counterfeit of any brand is the least safe product in the house.

The four layers of a safe installation
- Wire that resists fire and smoke: Finolex Flamegard FR-LSH or Finoultra.
- Breakers that protect the wire: Legrand DX3 MCBs, each sized to the wire on its circuit.
- Protection for people: a 30 mA Legrand RCCB, which trips on earth leakage in milliseconds.
- Safe points: Legrand shuttered sockets and a proper earth pit.
Genuine is the biggest safety factor
A duplicate wire has less copper than the label says, so it runs hot on a load it should carry. A duplicate MCB may not trip at all. That is why we tell buyers to verify every Finolex coil with both QR codes and to buy Legrand from a stockist at a sensible price.
Finolex cartons carry two QR codes: an outer code on the carton label and an inner code you reach only after opening. The outer one proves the carton is registered with Finolex; the inner one proves the contents are what Finolex packed. Scan both, at your site, before you pay. Our Finolex wire scanner does it in the browser.
