The PrimeTest Elite is the Australian version of the UK tester Apollo 600. If you are located in Australia then please contact our reseller there Emona instruments for more information (http://www.emona.com.au/). If you are in the UK then this unit would not be appropriate for your needs and you should look at the Apollo range of testers. Both types of tester will test portable RCDs without tripping the mains supply RCD.
Thanks and kind regards
