The Megger XTL30 and XTL50 Extension Test Leads are convenient and compact long test leads, designed for direct continuity measurement
of R2 values.
When working on a dead system, disconnect equipotential bondingto 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.
The XTL30 and XTL50 are 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.
