For a 2-ton air conditioner (AC), the size of the MCB (Miniature Circuit Breaker) depends on the current rating of the AC and the wiring system you are using.
A 2-ton AC typically consumes between 2000 to 2500 watts of power, depending on the efficiency of the model. Assuming it runs on a 230V supply, the current can be calculated using:
\[
\text{Current} (I) = \frac{\text{Power} (P)}{\text{Voltage} (V)}
\]
For example, if the AC is consuming 2400 watts:
\[
I = \frac{2400}{230} \approx 10.43 \text{ amps}
\]
Now, when selecting an MCB, you generally add a safety margin of about 25–30% to the rated current to handle any inrush currents or sudden spikes when the AC starts.
So:
\[
\text{Required MCB rating} = 10.43 \, \text{amps} \times 1.25 \approx 13 \, \text{amps}
\]
Thus, a 16A MCB is a common choice for a 2-ton AC, as it's a standard size and provides a good safety margin for typical residential or commercial setups.
Make sure to check the manufacturer's recommendations for the exact model of the AC as well, because different models might have slightly different current draws or inrush characteristics. Also, ensure your wiring is capable of handling the current!
