Is a connection to ground required at separate buildings or structures to establish a reference to ground?

A connection to ground is indeed required at separate buildings or structures to establish a reference to ground. This practice is crucial for several reasons. Firstly, grounding provides a safety mechanism to prevent electric shock and damage to electrical equipment. When multiple buildings or structures are involved, especially on the same property, each one can have different ground potentials due to variations in soil resistance, moisture content, and other environmental factors.

Connecting them to a common ground reference helps ensure that there is a consistent voltage level across all structures. This reduces the risk of electrical faults and enhances the effectiveness of protective devices such as circuit breakers and fuses. Moreover, grounding serves as a means to dissipate excess voltage from surges caused by lightning or other transient overvoltages, safeguarding both people and property.

In summary, establishing a connection to ground in separate buildings or structures is essential for safety and equipment protection, making the statement true.
