How many amps does a 1.5 ton Ac use?
Circuit Breaker(MCB Trip) activates during operation.
| Capacity | Current (AMP) | Breaker size |
|---|---|---|
| 0.75 ton | 5~6Amp | 16 Amp |
| 1.0 ton | 6~7Amp | 20 Amp |
| 1.5 ton | 8~10Amp | 32Amp |
| 2 ton | 15~16Amp | 40Amp |
Which MCB is best for 1.5 ton split?
The Ac of 1.5 tr usually needs a current of 6 amperes, so usually we can go for 8/10amps Mcb with a withstand current capacity of 36amps.
What is the starting load of 1.5 ton Ac?
The cooling capacity is 1.5 ton. The running current will be 1510/ 220 if the supply voltage is 220 V AC. The starting current of a 1.5 ton 5 star split AC with no gas is estimated to be around 15 to 20 A.
What size breaker do I need for my Ac unit?
Sizing an air conditioner circuit breaker
| Breaker or Fuse (amps) | Min. copper wire size (AWG) |
|---|---|
| 20 | 12 |
| 30 | 10 |
| 40 | 8 |
| 55 | 6 |
How do I choose an AC breaker?
Get a circuit breaker with slightly more amps of electrical output capacity than what your air conditioner requires, just to be on the safe side. Circuit breakers must have the capacity to feed current to the devices they lead to.
What size breaker do I need for a range?
The suggested circuit breaker size for the kitchen stove is 50 amps, 220 volts. This is a double breaker. Single breakers normally carry 110 volts. It must be a dedicated circuit for the stove only, meaning that no other appliances or outlets can be served by that circuit.
What size circuit breaker do I need for my air conditioner?
To determine the right circuit breaker size for an air conditioner, we look at both the minimum and maximum size allowable. The maximum size will be clearly labeled on the compressor label. In the example below, it’s 60 amps.
What size circuit breaker do I need for a rotary compressor?
For AC with a Rotary Compressors, the rating of MCB may be 10 amps. If your 1.5 ton AC is rated for a power of 2kw, it draws a current of 8.4 amperes during the time of normal operation, but at the time of starting it it draws a more current than it’srated current so it will be better to have 12 amp, circuit breaker, but 12 amp.
What size wire do I need for a 20 amp breaker?
This 2.5 ton unit specifies a 20 amp breaker which by normal NEC rules requires 12 AWG wire but the minimum ampacity is only 12 amps here so 14 AWG wire good for 15 amps can be used instead if the wire length isn’t very long. Personally I woul
What is the size of the MCB used for AC?
For old window type 1.5 Ton AC, the rating of MCB used, may be 16 Amps (assuming Voltage rating of supply is 230 Volts), For split AC of 1.5 Ton the MCB used, may be of 12 Amps rating but as MCB of 12 Amps may not be available MCB of 16 Amps may have to be used
