How to Use the GT85 Socket Tester
- Before use, inspect the tester for any damage
- Test on a known correct socket first to verify tester function
- Insert the tester into the socket to be tested
- Read the LED indicators to determine wiring condition
- Press the RCD test button to verify RCD trip function (only works on correctly wired sockets)
- If wiring errors are detected, contact a professional electrician for repair
RCD (Residual Current Device) Testing
The GT85 features an RCD test button that simulates a 30mA fault current. When pressed on a correctly wired socket protected by an RCD, the RCD should trip within the specified time (typically 30ms). This verifies that the safety device is functioning correctly and will protect against earth leakage faults.
Important Safety Notes
- Before testing RCD, disconnect sensitive equipment that could be damaged by power interruption
- Ensure power failure during RCD testing will not cause harm or data loss
- Testing in public places must be approved by the facility manager
- If wiring errors are detected, consult a professional electrician for repair
- Do not use the tester if it appears damaged
