The CBT3 and CBT4 are hand-held instruments for testing residual current protective devices (RCDs) in wiring installations. The instruments are connected through a normal mains socket outlet or directly via the RCDs terminals. Neons indicate if there are no open circuits in the installation and if the phase connections are correct. |
