2.3.1 Overvoltage Category
The IEC defined the term Overvoltage Category (sometimes referred to as Installation Category) to
address transient voltages. Category IV devices can handle the largest transients relative to the
normal working voltage. Category I devices can handle only small transients.
Voltage transients are defined as short duration surges of electrical energy. Repeatable transients
are frequently caused by the operation of motors, generators, or the switching of reactive circuit
components. Random transients, on the other hand, are often caused by lightning and electro-
static discharge. Ensure that the possibility of transient voltages on the mains line are minimal to
prevent damage to the system.
