Conductor Color Coding Chart

North American and international cable have different conductor color codes. Marking of the conductors within the cable defines which conductor is ground, neutral, and line. Interpower has created a chart to help differentiate between the conductor color codes.

Guide to World Wide Plugs/ Socket Patterns & Power Mains (Single-Phase)

A number of plug patterns are used throughout the world, so determining the correct one is essential. Interpower offers a Guide to Worldwide Plug and Socket Patterns and Power Mains (Single-Phase) that gives frequently specified plug patterns by country. This guide also has information on the world’s voltage and frequency requirements.

IEC 60320 Appliance and Interconnection Couplers

The IEC 60320 Appliance and Interconnection Couplers chart illustrates IEC 60320 connectors, inlets, plug connectors, and outlets in their different families. For example: IEC 60320 C13 connector and C14 inlet are in the Class I, Cold family, along with the IEC 60320 Sheet E plug connector and Sheet F outlet. The IEC 60320 C15 connector and the C16 inlet are in the Class I, Hot family.

International Cord Set Configurations

The International Cord Set Configurations chart is a reference to show which global plugs and IEC 60320 connectors are allowed in combination as a cord set.

A cord set is defined as an assembly consisting of one flexible cable or cord fitted with one plug and one connector.

Harmonized Wire Coding System

This Harmonized Wire Coding System chart explains the Harmonized system and what the code means. Illustrated in the chart is the code for H05VVF3G0.75.

IP (Ingress Protection) Codes

IEC 60529 outlines an international classification system for the sealing effectiveness of enclosures of electrical equipment against the intrusion into the equipment of foreign bodies (i.e. tools, dust, or fingers) and moisture. This classification system utilizes the letters “IP” (“Ingress Protection”) followed by two digits. This chart gives the degrees of protection for the first and second digits.
