What is a true statement about 240-volt breakers?

A true statement about 240-volt breakers is that the handles should be tied together. This is important because 240-volt breakers are typically used for circuits that supply power to large appliances such as dryers, water heaters, or air conditioning systems, which require both phases of a 240-volt source. Tying the handles together ensures that when one breaker is turned off, the other is also disconnected, providing a safe way to isolate the circuit for maintenance or emergency situations.

This practice helps prevent potential hazards such as one leg being live while the other is turned off, which could lead to electrical shock or damage to appliances. A tied-together configuration guarantees that both phases are simultaneously switched off, ensuring greater safety for anyone servicing the equipment connected to that circuit.
