Testing portable RCCBs/PRCDs
• Connect the connector on the mains cable to the low-power
connection (11).
•
Connect the plug to a 230 V mains (earthed) socket. The
voltage measurement will be applied automatically.
• Error message is displayed for
approx. 2 seconds if L wire of
mains socket is not correct.
• The portable RCCB/PRCD should be put into the test socket (1).
• Connect the supplied IEC low-power cable to the IEC
connector (10) on the GT-6000 v2.
• Put the safety plug into the socket of the portable RCCB/
PRCD. The plug must be oriented as shown on picture on
the right side.
• By pressing the button (6) the mains voltage is applied to the
test socket. The symbols “rCd” and “rESEt” are displayed.
• Switch on the portable RCCB/PRCD.
• Two errors may occur:
-
If “rESET” warning is displayed continuously and the symbols “LN” and “LE” are flashing, should be checked if
RCCB/ PRCD is switched on.
-
If RCCB/ PRCD is switched on and the message “IEC Volt Error” is displayed on the display, safety plug in the
socket of the RCCB/PRCD need to be rotated by 180°
.
• By pressing the button (6) the test will be restarted.
• RCCB/PRCD should be switched back on, each time when “rESEt” symbol is displayed.
• The portable RCCB/PRCD is tripped by fault current of 30 mA with 0° or 180° initial polarity. The tripping times
caused by such single rated fault current are measured.
• Tick symbol is displayed next to the tripping time value if the tripping time is less than the limit (200 ms).
• If tripping time caused by the single rated fault current is inside limit, GT-6000 v2 will generate 150 mA fault current
with 0° or 180° initial polarity. The RCCB/RCD is tripped, and the tripping times caused by this five-fold rated fault
current will be measured.
• Tick symbol is displayed next to the tripping time value if the tripping time is
less than the limit (40 ms).
•
“PASS” will be shown on the display if whole test is successfully finished.
In some cases, the portable RCCB/ PRCD need to be plugged into a mains socket (which is not protected
by any other RCCBs) – test should be done like for permanently installed RCCBs/RCDs.
