Long Test Lead with 4mm Shrouded Banana Connectors

Built for electrical testing where standard test leads simply aren't enough.

Anyone who's carried out testing across large electrical installations knows the frustration. Standard test leads quickly become the limiting factor, forcing temporary extensions, multiple setups or repeated trips between test points.

Developed alongside professional electrical testing engineers, our Long Test Leads provide a practical solution for reliable long-distance testing where standard test leads are no longer practical. Every assembly combines flexible heat, oil and flame-resistant coil end lead, professional CLIFF test connectors and genuine Schill cable drums, bringing together proven components selected for reliability, flexibility and repeated field use.

Performance & Build Quality

Every Long Test Lead is handmade in our UK workshop using flexible 1.5mm² heat, oil and flame-resistant coil end lead, professional CLIFF 4mm shrouded banana connectors and genuine Schill cable drums selected to suit the chosen cable length. The fine-stranded Class 5 tinned copper conductor gives the cable excellent flexibility, making it easier to deploy, recover and wind back onto the drum during repeated use. Every assembly is individually inspected and electrically tested before dispatch.
