What is the minimum voltage at which RPE can be used safely over uninsulated conductors?

The minimum voltage at which RPE (Rubber Protective Equipment) can be used safely over uninsulated conductors is 600 VAC. This standard is established to ensure adequate safety for workers who may be exposed to electrical hazards.

At voltages below this threshold, the risk of electrical shock and arcing increases significantly, as the insulation and protective equipment may not provide sufficient protection. RPE is specifically designed to withstand higher voltages, ensuring that workers can operate safely even in environments where uninsulated electrical conductors are present.

Using RPE at a voltage of 600 VAC or higher ensures that the equipment's dielectric properties are effective enough to protect against electrical breakdown and potential hazards. Thus, it is crucial for safety protocols to adhere to this minimum voltage requirement, which helps to safeguard workers from electrical injuries.
