Yes, they’re insulated and rated up to 1500V DC, meeting IEC 60900:2018 and ASTM F1505-16(2021) standards for safe use on live solar circuits when used correctly by trained personnel.
Unlike basic plastic tools, the A-68426S features steel inserts for durability and accuracy, combined with insulated TPE handles for professional-grade electrical protection and comfort.
