Megger Extension Test Lead On Reel 50m R2

Compact extension test lead for direct R2 measurements so eliminating the need for crossover connections and R1 + R2 measurements. The furthest point in the circuit can be easily verified, and every earth point on the circuit checked for integrity prior to energising.When working on a dead system, disconnect equipotential bonding to eliminate parallel paths and connect one end of the lead to the main Earth terminal at the distribution board. Connect the other end of the lead to your continuity tester, and probe around the circuit CPC points checking for continuity, and direct R2 measurements.This compact 30 m or 50 m extension test lead eliminates the need for crossover connections for R1 + R2 measurements by providing a single R2 value. The furthest point in the circuit can be easily verified, and every earth point on the circuit checked for integrity prior to energising.Ideal for use on lighting circuits to check switches and roses where R1 + R2 is not possible, and on multi-light arrays (e.g. commercial and retail premises) to ensure every fitting is earthed with minimal disassembly.This is also useful for general fault finding on new and in-use circuits where a loop break may be present or an open circuit fault exists at some distance from the distribution board.The small and light design is easy to carry and use. The outer frame is convenient to hold, with the low-friction drum preventing over-run for tangle-free extension, combined with a cable tensioning brush for easy rewind.Both are supplied with a 1.5 m inter-connection lead and croc clip. · · · Suitable for direct R2 measurement · · Easy re-wind of cable with tangle-free cable guide · · Tough, compact and light design · · A choice of 30 or 50 metres
