1. Wire Types & Safety Grades

Modern wiring is all about fire suppression. Always check for these markings:

  • FR (Flame Retardant): Standard residential use. Resists catching fire.
  • FRLS (Flame Retardant Low Smoke): Reduces toxic smoke during a fire. Essential for high-rises.
  • ZHFR (Zero Halogen): Premium grade. No toxic gases at all. Recommended for kids' rooms and luxury villas.

2. Wire Size & Load Capacity Chart

Size (sq.mm) Max Current Best Use Case (Safe Application)
0.75 / 1.010A - 12AInternal light points, fans, small electronics.
1.515A - 16AExhaust fans, 1000W irons, lighting circuits.
2.520A - 22AGeysers, 1-Ton AC, Power Sockets.
4.028A - 30A1.5-Ton & 2-Ton ACs, Main Line to DB.
6.035A+Main Meter to Main Switchboard connection.

3. Copper Quality: Electrolytic vs Local

Branded wires use 99.9% Pure Electrolytic Grade Copper. Non-branded wires often use "Scrap Copper" or alloys.

  • Conductivity: Impure copper creates resistance, making the wire heat up even at low loads.
  • Flexibility: High-grade copper (found in Finolex or Polycab) can bend 100+ times without snapping. Cheap copper turns brittle in 2-3 years.

4. Wire Markings & Color Codes

Identify your wires using the Standard Indian Color Code (2026):

Red/Brown: Phase (Line)

Black/Blue: Neutral

Green/Yellow: Earth (Safety)

Pro Tip: Look for the "IS 694" mark printed on the wire. This ensures it meets Indian Safety Standards.
