Update:
1. I replaced the 22 year old Merlin Gerin RCBO with a new Schneider RCBO. In four days, the new RCBO did not trip, but the Blue Sea ELCI tripped once on day two but not again.
2. I have installed the
B-Stop.
I set the preset of device to null out 5mA of leakage current. No trips in the past two days.
Here are some pictures of my test results using a Hioki 3283 current leakage tester.
• No B-Stop, 0.42 mA, Shore power off, innverting mode
• B-Stop, 1.26 mA, Shore power on, inverters breakers off, in inverting mode
• No B-Stop, 5.51 mA, Shore power on, inverter power breakers on, in the inverting mode
• No B-Stop, 18.9 mA, Shore power on, inverters in pass-through mode, 251 V, 60 Hz
• B-Stop active, 4.28 mA, Shore power on, inverter breakers on, no pass through, inverting on
• B-Stop active, 5.71 mA, Shore power on, inverting, no inverting pass through
• B-Stop active, first on the leakage starts at 9.68 mA, shore power on, inverter breakers on, inverter pass through on 251 V, 60 Hz
• B-Stop active, settles at 12.3 mA in a few minutes, inverter pass through, MW on, IP43 Charger on
