What does 'RLA' mean in HVAC terminology?

'RLA' stands for Rated Load Amperage in HVAC terminology. This term specifically refers to the amount of electrical current, measured in amperes, that the compressor of an air conditioning or refrigeration system requires to operate at its rated capcity. It is an important specification because it helps determine the correct size of electrical components, such as circuit breakers and conductors, ensuring that the system operates efficiently without overheating or damaging the electrical system due to excessive current draw.

Understanding RLA allows HVAC technicians and engineers to assess whether the electrical supply to a unit is adequate for its operational needs, which is crucial for both efficiency and safety. Properly matching the electrical demands of a system to its power supply is vital for maintaining the longevity of the equipment and preventing potential failures.
