Safe Isolation Kit - 

Safe isolation procedures are a fundamental part of complying with the law and reducing the incidence of electrical accidents. The TB118 kit includes the tester and proving unit for performing a safe isolation procedure, two lock off devices and an advanced socket tester that will indicate whether it is safe to connect to the installation. Especially of interest to gas engineers and compliance to the TB118 GAS SAFE directive. To ensure that you are connecting into a circuit that is safe, a loop safety check is required. For that we have also included the LOOPCHECK 107 advanced socket tester with loop check, socket and mains polarity and RCD check.
