1p空調掛機配多大的空開和漏保？

The size of the circuit breaker and the RCD (residual current device) required for a 1p (single-phase) air conditioner will depend on the power rating of the appliance. The power rating of the air conditioning system will typically be given in watts or BTUs (British Thermal Units)， and the electrical supply must be capable of delivering this power safely.

Generally， for a 1p air conditioner， a circuit breaker of 10 amps and an RCD of 30mA are commonly used. However， it is always best to consult with a licensed electrician or an expert in HVAC systems to determine the appropriate size of breaker and RCD for the specific air conditioning system.

When choosing a breaker， it is important to select one that matches the voltage of the air conditioner's power supply. For single-phase air conditioners， a 240V breaker will be needed. It is also important to consider the ambient temperature of the environment where the air conditioning system will be installed. This will affect the load on the system and the size of the breaker required.

In addition to the breaker， an RCD should always be installed to protect against electrical shocks and potential hazards. The RCD will detect any leakage of current from the circuit， and if any fault or leakage detected， the RCD will immediately trip the circuit to prevent injury or damage to the system.

In summary， a 1p air conditioning system should ideally have a circuit breaker of 10 amps and an RCD of 30mA or above， depending on the specific power rating and other environmental factors. It is always best to consult with a professional electrician or HVAC technician to ensure the safe and efficient operation of the system.
