How do you convert LRA?
LRA (lock rotor amps) can be converted to HP using this formula: (LRA Watts x Volts)/ 746 Watts = Horsepower. You can also use the BTUh. For example, 18,000 BTUh equals 2 HP or 24,000 2.5 HP.
What does LRA on a compressor mean?
Locked Rotor Amperage
The compressor can operate as a single stage, where it is on or off, multiple stage where it is run at different power levels, or variable speed. These compressors draw a lot of current when they start up. This current is typically called startup, inrush, or Locked Rotor Amperage (LRA).
How much current does a 5 ton AC draw?
An average 5-ton air conditioner (with 10 EER rating) will run on 6,000 W. Such a 5-ton air conditioner will use 25 Amps at 240V. Examples of 60,000 BTU units are 4-zone mini-splits and 5-zone mini-split air conditioners.

What is LRA?
A less restrictive alternative (LRA) is outpatient treatment provided to an individual who meets criteria for commitment but is not residing in a facility providing inpatient treatment. The DMHP must then file a petition with the court for revocation of less restrictive alternative treatment.
Is LRA the same as starting amps?
Locked rotor current is basically the current drawn by the motor at its rated voltage when its rotor is kept stationary or in other words rotor is not spinning or rotating. So when we start a motor, its rotor is already at rest. This means, starting current and locked rotor current should be same.
How do you calculate LRA?
To find LRA and starting kVA enter nominal operation voltage (such as 120 or 240), HP value, code letter from the nameplate label, and hit “Calculate” button. The general equation for single-phase devices is the following: LRA=1000*(kVA/HP)/Voltage.
What size breaker do I need for a 5 ton AC unit?
You can most likely use 8-2 w/ground. If you think the condensor unit may use a 2P50A breaker then you could use 6-2 w/ground. Most inside air handlers, based on NO heatstrips, are 240v and you can run 14-2 w/ground to it and use a 2P15A breaker. You could also use 12-2 w/ground if you like to be extra sure.
How many watts is a 4 ton AC unit?
The exact amount of Watts needed for a 4 ton air conditioner depends on the make and model of the AC unit, as well as how often it’s running. A safe estimation is that it takes 14,000 Watts, or 4 Kilowatts. If you’re using a generator, it’s best to use a 17 KW generator to ensure that you have enough power.

What is an LRA rate?
Within a corporate travel programme, Last Room Availability (or LRA) means that as long as a hotel has a room for sale, even one room, then parties with an LRA contract have a right to buy it, at their contracted terms and prices. The negotiated rate is available to travellers at the discretion of the hotel.
