Dedicated 20A circuit from DB box to AC location — 4mm² wire, correctly rated MCB, AC isolator switch and earthed socket — done right by our licensed electricians in Mathikere. All AC brands, same day.
An AC point installation in Mathikere means running a brand new circuit from your DB box to the location where your AC indoor unit will be fitted. This circuit carries only the AC load — nothing else. The wire run is typically 4mm² 3-core FRLS PVC cable — sized for the full starting current of up to a 2-ton AC. A 20A MCB in the DB box protects the circuit. A 20A double-pole isolator switch is fitted near the AC unit so the AC technician can safely isolate power during servicing without going back to the DB box.
For a 1-ton AC, 2.5mm² cable and a 16A MCB is technically sufficient — but we always recommend 4mm² with a 20A MCB for all AC circuits in Mathikere homes. This gives headroom to upgrade from 1T to 1.5T or 2T without rewiring the point, and a 4mm² cable runs cooler under sustained load — important in Mathikere's warm climate where ACs run 8–12 hours a day in summer.
The most common AC wiring problem we encounter in Mathikere homes is a 1.5-ton or 2-ton AC that was installed by the AC technician using the existing general socket wiring — typically 2.5mm² wire on a 16A shared circuit. Within a monsoon season, the socket is visibly discoloured from heat, the MCB trips regularly, and the AC compressor develops startup problems from repeated voltage brownouts caused by insufficient circuit capacity.
We also repair AC wiring faults — tripping MCBs, overheating sockets, broken earth wires and loose AC isolator connections. If your AC is tripping its MCB repeatedly or your AC socket is hot to the touch, call us immediately — a loose connection at a high-current AC circuit is a genuine fire risk. Call 7411225242.

Using the wrong cable size or MCB rating is the single most common AC wiring mistake in Mathikere. Here is the correct specification for every AC capacity.
| AC Capacity | Running Current | Cable Required | MCB Rating |
|---|---|---|---|
| 0.75 Ton (Window) | 4–5A running / 8A startup | 2.5mm² 3-core FRLS minimum | 16A dedicated MCB |
| 1 Ton Split AC | 5–6A running / 10A startup | 4mm² 3-core FRLS recommended | 16A or 20A dedicated MCB |
| 1.5 Ton Split AC | 6–8A running / 12–14A startup | 4mm² 3-core FRLS — mandatory | 20A dedicated MCB |
| 2 Ton Split AC | 9–11A running / 16–18A startup | 4mm² 3-core FRLS — mandatory | 20A or 25A dedicated MCB |
| Inverter AC (all sizes) | Variable — lower running current | 4mm² 3-core FRLS recommended | 20A dedicated MCB — startup spikes still occur |
| Shared socket circuit | ✘ NEVER — dedicated circuit always required. Shared circuits cause MCB trips, socket overheating and compressor damage. | ||
Note — all AC brands sold in India (Daikin, Voltas, LG, Samsung, Carrier, Blue Star, Hitachi, Panasonic, O General) require a dedicated earthed circuit. Running an AC on a shared socket without a dedicated circuit may void your warranty. Call 7411225242.
