Seaward NTB-1 Portable RCD Isolator - 372A953

The Seaward NTB-1 Portable RCD Isolator is an adaptor for use when RCD testing that allows users to test a portable RCD or RCD protected extension lead without the risk of tripping the main RCD in the installation. The NTB-1 portable RCD adaptor does this by providing an isolated mains supply which prevents unwanted tripping of any RCD at the main distribution board or consumer unit. This enables the user to continue testing without the worry of causing disruption to the premises they're working on. The Third Edition of the IEE Code of Practice has meant increased significance of RCD testing and it is now a common electrical test procedure. Many PAT testers now incorporate an RCD test and the Seaward Non Trip Box is a lightweight RCD adapter that can be used easily and effectively with any make of PAT tester or RCD test instrument.
