Choosing the Right MCB:
16A vs 25A for Air Conditioners
The most common electrical mistake in Indian AC installations. Use this table as your reference — or use the calculator above for your exact configuration.
Why Type C MCB — Not Type B?
Type B MCBs trip at 3–5× rated current. AC compressors — especially fixed-speed — draw 5–8× rated current at startup. Type C MCBs trip at 5–10×, handling the inrush without nuisance tripping. Always specify Type C for AC circuits.
Dedicated Circuit — Non-Negotiable
Every AC must have its own dedicated circuit from the distribution board. Sharing a circuit with other loads causes voltage drops, MCB trips, and PCB damage. IS 732 mandates dedicated circuits for loads above 1.5 kW.
Why Wire Gauge (sq mm) is
Critical for Inverter ACs
Undersized wiring is the #1 cause of AC PCB failures and electrical fires in Indian homes. Here's the complete guide.
Danger Signs: When to Call an Electrician Immediately
Wire feels warm to touch after 30 min of AC use
MCB trips within 5 minutes of AC startup
Visible discolouration or melting on wire insulation
Voltage drops when AC starts (lights dim briefly)
AC trips occasionally but restarts fine
Wire runs through conduit with other high-load cables

Pre-Installation Safety Checks
Tick off each item before your AC installation. Critical items (marked in red) must be verified — they directly affect safety and warranty validity.
