Which mm Wire Required for 1.5 Ton AC?

Wire sizes are influenced by a number of factors, including room temperature and current loss, in addition to the electric current. I probably meet with wire fitting tasks when I operate air conditioners. So let me tell you which mm wire required for 1.5 ton AC.

How much mm wire required for 1.5 ton AC?

You need to divide the maximum current by 80% to get the capacity of the power switch when determining the wire size for air conditioners. Then, calculate the permitted voltage drop using the wire length and a 2.5% voltage drop. Decide on the appropriate wire size depending on the permitted supply voltage and circuit ampere.

So you will need 2.5 mm wire for a 1.5-ton AC. It will help the AC to work more efficiently and provide more lifespan to both AC and electrical wiring. Now you know how much mm wire is required for 1.5 ton AC.

I hope you understood which mm wire required for 1.5 ton AC.

Last summer, I got my 1.5 Ton Blue Star AC installed in my room. At that moment, I asked the AC technician, how much mm wire for 1.5 Ton AC required. According to him,

Moreover, he has informed me of several factors to calculate the exact wire size. I have shared the same below for your reference.

What is the 1.5 Ton AC Cable Size?

As I mentioned above, a 2.5 square mm will be enough for 1.5 Ton AC. This is so because a 1.5 Ton AC wattage is 1800 and a 2.5 square mm wire can carry 22 Amperes, which is multiplied by 220 voltage to generate 4800 wattage. 

Let’s check out the aspects that affect the wire size:

• The

  AC unit's drawn current

  is the main factor to take into account. It is crucial to choose a wire that can safely transmit this amount of current without excessive heat or posing electrical risks to figure out the proper wire size.

• You also need to think about the

  wire length

  . Voltage drops along longer wire runs may have an impact on the AC unit's performance and effectiveness. It is required to choose a larger wire size to account for these possible voltage drops.

• An additional significant factor is the

  ambient air temperature

  . You will require a larger wire size for higher temperatures.

• The

  temperature at which wires operate

  is another crucial factor. You will require a smaller wire size for higher temperatures.

• You must consider

  wire material

  . Select copper wire for your air conditioner because it is a superior conductor to aluminum.

• Installation

  is another important component. Trunking-enclosed wires perform worse than those run on perforated cable trays.

To determine an appropriate gauge depending on the particular installation settings, you can also speak with an AC technician and get it installed from the below link.

Until I bought an AC I wasn't aware that the wire size of an AC is not just dependent on the electric current. I have been facing a problem with my AC wire burning from time to time. so I consulted an electrician. The problem was with the wire size of my AC. He told me that a 1.5 ton ac wire size is dependent on other conditions as well like the voltage drop and the ambient temperature. Let me explain to you what else he told me.

Wire size for 1.5 ton AC 

• From what my electrician explained to me, I can tell you that in order to calculate the wire size for an AC divide the current of the AC by 80% in order to find the circuit breaker size.

• After this, we need to calculate the allowable voltage drop which is calculated by using the wire length and a voltage drop of 2.5%.

• Lastly, we can choose the size of the wire of an AC on the basis of the circuit breaker ampere and the allowable voltage drop.

What is 1.5 ton split AC wire size?

Only the hot, neutral, and ground wires are used in single-phase (230-volt) air conditioners. As a result, the wire contains more current than a three-phase system (480 volts).

In this manner, single-stage forced air systems use thicker wires than three-stage climate control systems.

The table mentioned by Nelson shows the suggested wire size in light of the climate control system limit as well as the most extreme current of different single-stage forced air systems.

How to calculate the wire size for AC?

1) Recognize the load

Determine the capacity to generate electrical current before estimating the cable size. The energy going through the cable is essentially the same for devices like fan motors and compressors. For air conditioners, it is certainly different.

2) Choose the appropriate power switch size

You must determine the size of the power switch. Calculate the air conditioners’ maximum current and divide it by 80% to get the right size power switch for them. The size you need will be the following nearest power switch size.

3) Analyse the voltage percentage

You must verify the voltage drop in order to prevent low voltage issues with your air conditioners and other devices. It will help you to determine if it is under an allowed percentage after determining the wire size based on the current carrying capability.

4) Select the wire size according to the current carrying limit.

You can utilise the circuit breaker ampere in order to determine the appropriate wire size by current-carrying capability. You are free to use the wire current-carrying capability chart or another wire modern capability chart. It can be in reference to your preferences and professional standards.

Aside from the electric flow, wire sizes are additionally relying upon different circumstances, for example, surrounding temperature and voltage drop. Wire sizing work will almost certainly be encountered when working with air conditioners. In this answer, I've tried to explain about 1.5 ton AC wire size.

Which wire is best for 1.5 ton AC ?

Divide the maximum current by 80% to determine the size of the circuit breaker for the air conditioner wire. The allowable voltage drop can then be determined by using the wire length and a voltage drop of 2.5%. At long last, pick the reasonable wire size in view of the electrical switch ampere and the suitable voltage drop.

Which wire is used for 1.5 ton AC ?

For many people, including engineers, sizing wire has been a challenging task. For a great many people, using the accompanying wire size outline ought to be adequate. For engineers, I'll go through bit by bit the most proficient method to work out wire size.

Cable size for 1.5 ton AC: Wire Size Chart by Air Conditioner Capacity

• Wire length = 50 ft (15 m)

• Ambient temperature = 86°F (30°C)

• Voltage drop = 2.5%

• Wire material = Copper

Is 2.5 mm wire enough for 1.5 ton AC?

Due to the fact that its maximum current can reach up to 10 amps, the wire size for 1.5 ton inverter AC would be 2.5 mm2 or 14 gauge to operate safely. Similar to this, 6mm2 or 10-gauge wires are required for a 3-ton air conditioner that operates on single-phase power.

This is all about 1.5 ton AC wire size.
