Safety Reference Guide
International safety standards
Test equipment must be designed to protect people who work in the high-voltage, high-current
environments. In order to prevent injury, the International Electrotechnical Commission (IEC)
develops international general standards for safety of electrical equipment for measurement,
control and laboratory use. The most current standard 61010 specifies overvoltage categories for
electrical distribution systems. The category rating increases based on the closeness to the power
source and a higher level of user protection that is required from test equipment.
Proposed Energy Regions*
CAT I
Electronics, signal level single-phase receptacle loads
CAT II
Appliances, portable tools
CAT III
Three-phase distribution, large building lighting systems, distribution panel devices
CAT IV
Three-phase at utility connection, electricity meters, outside and service entrance
* Category ratings per IEC1010-1. Category boundaries may not be exact.
