3 Phase App/Ext/RCD
3 Phase Appliance / Extension / RCD Adaptor
The 3 Phase APP/EXT/RCD Multi adaptor has been designed to conduct the required tests for 3 phase equipment, RCDs and Extension Leads using a single phase appliance tester.
The rotary switch will isolate each phase and will allow Earth continuity and Insulation resistance testing on the appliance under test or Polarity testing on a 3 phase extension lead. This same switch is used to conduct the RCD trip times on each phase on a 3 phase RCD.
The innovative design has incorporated both 20amp and 32amp 4/5 pin 3 phase sockets and 20amp and 32amp 5 pin plugs.
