How much lower are use voltages compared to test voltages in rubber gloves?

Rubber gloves used by linemen are tested at specific voltages to ensure they can safely protect the wearer from electrical shock. The test voltages are much higher than the actual service or use voltages that the gloves will encounter in the field. This is because the gloves are designed with a safety margin to account for various factors, such as wear and tear, environmental conditions, and potential damage that could occur during use.

When gloves are tested at higher voltages, it assesses their effectiveness and reliability in real-world applications, which involve lower voltages. As a result, the use voltages are indeed a little lower than the test voltages, meaning that the gloves are tested for higher levels of safety than what they will actually face in everyday use. This ensures that linemen are adequately protected while performing their duties.
