1 Installation category (overvoltage category) describes a number which defines a transient overvoltage condition. It implies
the regulation for impulse withstand voltage. “II” applies to electrical equipment which is supplied from the fixed installation
like a distribution board.
2 Applies to measuring circuits connected to low voltage installation, and electrical instruments supplied with power from fixed
equipment such as electric switchboards.
3 “Pollution degree” describes the degree to which a solid, liquid, or gas which deteriorates dielectric strength or surface
resistivity is adhering. “2” applies to normal indoor atmosphere. Normally, only non-conductive pollution occurs.
