Is this the right one for you?

Check these five things before you order:

• The circuit current is within 11 A enclosed in conduit or 12 A clipped direct (catalogue ratings for two cables in single phase, 40 °C ambient).
• You are wiring lighting points and switch drops.
• You want a lead-free flame-retardant wire that pulls easily through long conduit runs, at a mid-range price.
• 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 Primma 0.75 sq mm (7 A in conduit); for a heavier one, Polycab Primma 1.5 sq mm (14 A).

Frequently asked questions

What is the MRP of Polycab Primma 1 sq mm?

Rs 3,930 per 90 m coil - the MRP listed on polycab.com in October 2026, inclusive of taxes. Our selling price is quoted on enquiry: call +91 9340081159.

How much current can Polycab Primma 1 sq mm carry?

11 A enclosed in conduit (Reference Method B) and 12 A clipped direct (Method C), for two cables in single phase at 40 °C ambient, per the Polycab catalogue. Derate for higher ambient temperatures and for groups of circuits in one conduit.

What is the construction of Polycab Primma 1 sq mm?

32/0.21 strands (number/diameter in mm) of bright annealed electrolytic copper, LF FR PVC insulation 0.6 mm thick, overall diameter about 2.4 mm, maximum conductor resistance 19.5 ohm/km at 20 °C.

Is 1.0 sq mm enough for a fan point?

A ceiling fan draws well under 1 A, so 1.0 sq mm carries it easily. Many installers still run fan circuits in 1.5 sq mm so that lights and fans share one standard size with extra margin.

What does LF FR mean?

Lead Free, Flame Retardant: the PVC insulation contains no lead stabiliser and resists the spread of flame. Rated 70 °C.
