What is the voltage rating for a Class 4 type 2 blanket?

The voltage rating for a Class 4 type 2 blanket is indeed 40kV. This classification indicates that the blanket is designed to provide insulation protection against electrical voltages up to this level. In practice, such blankets are used to safeguard linemen and electrical workers when they are working near live circuits, helping to prevent electrical shock and provide a safe working environment. Understanding the voltage rating is crucial for safety and compliance with electrical safety standards, ensuring that the protective gear used matches the voltage levels encountered in specific job situations.
