42 LRA what ton - Heating & Cooling

Your 'power' is the 220 - 240 volts.

The installation manual will tell you all this. In North America with 110volts AC is normally on a dual 15 amp breaker. Your installer will set all this up.

LRA is locked rotor amperage. Has nothing to do with Tonnage. Also Tonnage is not used anymore. The rating is now called SEER

the lra will be on the compressor name plate

LRA on the data tag stands for "locked rotor amps" and has nothing to do with tonnage. In the model # there should be a number to use. And divide that # by 12 (12,000 btu/ton). So if I had a PFG24H200 it would be the "24"and a 2 ton unit

Yes you will have problems you can go up a 1/2 half ton on the coil but not with the condenser don't do it you will regret it even with an expansion valve.

One really has not much to do with the other directly

LRA - Lock Rotor Ampere-LRA is nothing but locked rotor current , generally it is located on compressors name plate, when ever pistons locked at a particular position the rotor does not move further at the time rotor draws large current, that current is located on name plate, by seeing that LRA we can know compressor rotor was locked
