Voltage Rating refers to what characteristic of electrical equipment?

Explanation:
Voltage rating is the maximum voltage the equipment is designed to withstand safely because it reflects the insulation strength and required clearances inside the device. This limit ensures the insulation resists breakdown and prevents arcing or shock under normal operation. Exceeding it can compromise insulation, leading to dangerous failures. This spec is separate from how much current the device can carry or from its size or wire color. Some equipment also has surge or transient ratings for short spikes, but the continuous operating voltage is defined by the voltage rating.
