Electrical systems that supply only industrial electric furnaces are permitted to be grounded, but not required to be grounded. Is this statement true or false?

The statement is true because electrical systems dedicated solely to industrial electric furnaces are permitted to be grounded as a safety measure, but it is not mandatory. This allows for flexibility in design and installation according to specific operational needs and safety considerations.

In many cases, grounding is implemented to enhance safety and reduce the risk of electrical shock or fire hazards. However, when the systems are exclusively serving electric furnaces, the requirement may be waived based on particular jurisdictional regulations or standards. This regulatory framework often considers the specific nature and usage of the equipment along with the operational environment, which can justify the decision to not require grounding in certain circumstances.

Therefore, understanding that while grounding provides numerous safety benefits, the context of use, along with regulatory guidelines, allows for exceptions that do not mandate grounding for these specific types of systems.
