Peak-blocked voltage is a term used to describe the maximum voltage that a device can handle without getting damaged. Synonyms for peak-blocked voltage include peak voltage, maximum voltage, surge voltage, and voltage overload. Peak voltage refers to the highest voltage level achieved in an electrical system, whereas maximum voltage is the highest possible voltage level that a device can handle. Surge voltage is a sudden increase in voltage that lasts for a short period of time, while voltage overload indicates excessive voltage that can damage the device. It is essential to understand the different terms related to peak-blocked voltage to ensure safe usage of electrical equipment and prevent damage to property and people.
