10 dumb things smart people do when testing electricity
Anyone who makes their living by working with electricity quickly develops a healthy respect for anything with even a remote chance of being “live.” Yet the pressures of the getting a job done on time or getting a mission-critical piece of equipment back on line can result in carelessness and uncharacteristic mistakes by even the most seasoned electrician. The list below was developed as a quick reminder of what not to do when taking electrical measurements.   1. Replace the…

IET Student’s Guide – Testing the continuity of circuit protective conductors (CPC)
This video was produced by the IET to guide apprentices through the correct procedures involved in testing the continuity of circuit protective conductors (CPC). Testing the continuity of the circuit protective conductor (CPC) is absolutely essential to confirm that your installation meets the requirements of the Wiring Regulations as well as to complete exams in accordance with the requirements of awarding bodies.   View all of the IET’s Student’s guide…

Measuring the continuity of the protective bonding conductor
In this video, Gary Hayers from Tresham College explains how you would go about measuring the continuity (resistance in Ohms) of the protective bonding conductor to water and gas. The video was made as a students training aid for testing continuity of the protective bonding conductor. This is the conductor that connects to the intake point consumers side of the metal gas pipe, metal water pipe and metal oil pipe in an electrical…

Checking continuity of a ring final circuit with unintentional spurs
This diagram provides guidance for checking the continuity and polarity of ring final circuit conductors with unintentional spurs for compliance with Regulation 612.2.2. This should be viewed as a continuation of the post: Checking continuity of a ring final circuit with no spur. Ensure installation, or appropriate part of it, is securely isolated, and proved to be so, before proceeding. Measurement to be taken at each and every socket outlet. Measured values…
