For temporary installations, receptacles must be of the grounding type. Which of the following statements is also true?

• A. Made of insulating plastic
• B. Protected at not less than 30 amps
• C. Of the grounding type
• D. All of these

Answer: (C)

For temporary installations, the critical safety feature is that the receptacle provides an equipment grounding path. A grounding-type receptacle ensures any fault current has a direct path back to the panel so the overcurrent device trips and the user isn’t exposed to a shock. The material of the receptacle or its exact amp protection isn’t what defines the requirement—the key point is the presence of a grounding connection. Saying it must be made of insulating plastic isn’t the defining factor, and requiring a specific protection level like not less than 30 amps isn’t a universal rule for all temporary setups. Since only the grounding-type characteristic is universally required, that statement is the correct one.
