Is this the right one for you?

Check these five things before you order:

• The circuit current is within 20 A enclosed in conduit or 23.1 A clipped direct (catalogue ratings for two cables in single phase, 40 °C ambient).
• You are wiring 6 A and 16 A socket circuits and dedicated circuits for small appliances.
• You want lead-free flame-retardant insulation at a mid-range price, with the standard 70 °C rating.
• A 90 m coil suits the job (180 m pouches of the Green Wire and LF FR constructions are listed separately).
• If the load does not fit: for a lighter circuit, Polycab Optima+ 1.5 sq mm (14.7 A in conduit); for a heavier one, Polycab Optima+ 4 sq mm (26 A).
