A window unit air conditioner operating at 240 volts would require which breaker to be installed?

To determine the correct breaker for a window unit air conditioner operating at 240 volts, it's essential to consider both the voltage requirement and the current rating of the air conditioner. Air conditioners typically have specific amperage needs based on their capacity, and this directly influences the size of the breaker required.

For a 240-volt window unit air conditioner, the breaker must be rated appropriately to support the electrical load while offering necessary protection against overloads and short circuits. Generally, a double-pole breaker is used for 240-volt appliances, allowing for proper distribution of power across both phases.

If Breaker A is the one that matches the specified voltage and is rated for the adequate amperage needed for the air conditioning unit, then it is indeed the correct choice. This selection ensures that the air conditioner operates safely and effectively without the risk of tripping due to under or oversized protection.

Understanding the electrical specifications of the appliance and matching them with the correct breaker type is a crucial aspect of electrical safety and system performance.
