372A953 Seaward NTB-1 A Compact and Portable RCD Isolator
■The Seaward NTB-1 solves an age old problem. It allows the user to test a portable RCD or RCD protected extension lead without tripping the main RCD on the installation.
■The Seaward NTB-1 is compatible with any RCD test instrument.
■The IEE Code of Practice requires RCD protected devices to be tested to ensure they are operating within the recommended time limits. The problem faced by many test operatives is that in order to test the operation of an RCD protected device, it must be connected to a mains supply. In many cases, the mains outlets in an installation are RCD protected themselves, in such cases it is possible that the main RCD will trip the installation before the RCD under test operates.
■The Non Trip Box eliminates this risk, by isolating the electricity supply to the RCD under test, allowing the test operative to continue testing without the worry of causing disruption to the premises they're working on by tripping the main RCD.
■In the past, isolation transformers have been used for this purpose, but these are bulky and typically weigh around 10kg in comparison to the Non Trip Box's lightweight 0.6
●Features
■Test portable RCDs without tripping the installation RCD
■Compact and portable
■Universally compatible with all RCDs and RCD test instruments
■Can be used in all situations and locations where an RCD test is required
