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 installation. The supply needs isolating and parallel earth paths.
