Modular Extension Test Leads

The Value Brand 4WRA6 kit provides two modular extension leads for use with any multimeter, clamp meter or test instrument that accepts a standard shrouded banana plug. The set includes couplers and is rated for CAT III 1000V and CAT IV 600V measurement categories, making it suitable for professional electrical testing environments.

CAT III 1000V CAT IV 600V Rating

Each lead features double insulation and 18 AWG wire, supporting a maximum current of 10 A at up to 1000 V. The shrouded banana plug connections ensure secure attachment to instruments while maintaining the safety ratings required for industrial and utility applications.

Extending Existing Test Lead Reach

These 1 ft 8 in extensions are designed for technicians who need additional reach between their meter and the test point without replacing their primary lead set. They are not intended for users who require longer fixed-length leads or higher current capacity beyond the 10 A rating.

Questions about this item

How do I connect the 18 AWG leads to my meter without a loose fit?

Push each shrouded banana plug straight into the meter jack until it clicks; the shroud locks the connection so vibration will not pull it out during use.

What part of the kit will wear out first and need replacing?

The double-insulation on the 18 AWG wire can crack after repeated bending; inspect the insulation before every job and replace the lead set if any conductor is visible.

At what point does the 10 A current rating become the limiting factor during a long test?

Sustained current above 10 A will heat the 18 AWG conductors past their safe limit, so the lead set must be derated or swapped for heavier leads before that threshold is reached.
