It depends on the motor, and whether there is already pressure in the tank.
Inrush (startup) currents can easily be 10x the running current.
So, you need to know what the running current is, then allow at least 10x that value for startup.
Be aware that 1.5 HP is around 1.1 kW, which implies about 10 amps on a 110 V line, about 4~5 A on 240 V, but your motor will be less than 100% efficient.
so... on 110 V, maybe 100 A (!) peak, on 240 V, maybe 50 A.
If you can measure the motor's DC resistance, then work out what current that would pull at line voltage, that will be the *maximum* possible current that the motor could draw.

What is the Current carrying capacity of 300sqmm copper wire?
in air it will be 665Amps.
How do you convert amp hours to amp minutes?
Divide by 60.
Is running your amp at 1 ohm bad for your system?
Only if your amp is rated to handle a 1 ohm load. If it's not you WILL... fry your amp.
What happens when a 70 amp hour battery is connected to a 50 amp hour charging circuit voltage of both batteries are being same?
The 50 amp charging circuit will never be able achieve a full charge for the 70 amp hour battery, thus in effect turning the 70 amp hour battery into a 50 amp hour battery.
How you can pass electricity 20 volt and 25 amp from converting 12 volt 1 amp adopter to 20 volt and 25 amp?
A 1-amp adaptor can not be used for equipment that draws more than 1 amp. It is not clear from the question which part of your system is 12 v and which is 20 v.
Can you use a 20 amp breaker for window unit air conditioner?
Yes, a 20 amp breaker is suitable for a standard window unit air conditioner. Make sure to check the manufacturer's specifications to ensure compatibility.
Can a 12000 BTU air conditioner run on 15 amp breaker?
It is possible for a 12000 BTU air conditioner to run on a 15 amp breaker, but it may cause the breaker to trip if there are other appliances drawing power on the same circuit. It is recommended to have a dedicated circuit for the air conditioner to prevent overloading the breaker.
How many amps will an 8000 btu air conditioner pull?
10.92 Amp
What size amp breaker for a 220V air conditioner?
The size of the amp breaker for a 220V air conditioner will depend on the specific requirements of the air conditioner. As a general guideline, you can calculate the required amps by dividing the air conditioner's wattage by the voltage (220V). For example, if your air conditioner is rated at 5500 watts, you would need a breaker of at least 25 amps (5500 watts / 220 volts = 25 amps). It is always best to consult the manufacturer's specifications or a licensed electrician to ensure the correct size breaker is installed.
Is a 40 amp circuit breaker ok for a 30 amp air conditioner?
No, it is not recommended to have a circuit breaker with a higher amperage rating than the device it is protecting. In this case, you should use a 30 amp circuit breaker for a 30 amp air conditioner to ensure proper protection from overcurrent.
Can a 4 ton central air conditioner run off a 30 amp breaker?
No, a 4 ton central air conditioner typically requires a minimum of a 40 amp breaker to operate safely and efficiently. Running it off a 30 amp breaker could cause the breaker to trip frequently due to overload.
How do you know if your air conditioner in overcharged?
With refrigerant gauges we read the pressures and measure the temperatures, without that we look at the amp draw and what the air temps are going in and out,
What if the plug and cord are hot on the air conditioner?
You may have a loose wire somewhere. You need to check the amp draw of the unit.
Is there an adapter that can be used on 230 volt 30 amp air conditioner appliance to make it fit a 220 volt 20 amp socket safely?
My electrician says no, has to be some rewiring.
Is it possible to power a 30 amp RV air conditioner with a generator with only two 20 amp outlets by combining the two 20 amp outlets to produce one 30 amp?
No, you need a 30 amp breaker (whether that's from a generator or not it doesn't matter) with the proper voltage.
Can you use a time delay fuse in your central air conditioner of the same amp rating?
Yes, and you should use a time delay fuse.
How big of a breaker do is needed for a 5000 btu air conditioner?
A 5 ton air conditioner will need a two pole 40 amp circuit breaker to supply 240 volts over a cable of #8 copper wires. Included in this cable will be a #12 bare ground wire.
