North American and International Power Mains

In this white paper, we will discuss National Power Mains. In the first portion of the white paper, we will discuss some of the basics of national power mains – voltages, frequency, polarization, Class I and Class II plugs, and approvals. We will also explore why you should not use country specific plug adapters or why cutting off the “wrong” plug and wiring on the “correct” plug could affect the approvals on your equipment. We will also address North American and Japanese power mains. (ADCs) together with a resistive temperature device (RTD) and thermocouple to measure temperature. Included are detailed examples of the most common configurations of a two-wire RTD, a three-wire RTD (with and without hardware compensation), a four-wire RTD, and a thermocouple with cold junction compensation. This document provides sufficient information to enable several alternate configurations to be implemented.
