My P1P triggers the residual current circuit breaker (RCCD, FI, RCD) reproducibly, i.e. always when the print bed temperature reaches 100°C. It is not the fuse (16A), it is the protective device that triggers at fault currents, in this case 40mA. I have tried several circuits with other RCCDs - the protection trips every time.
Is the problem known? I have opened a support ticket and hope that someone can help me.
I had a similar issue with my X1C. When heating the bed at full power (set to 110°C), the RCD would trip after two minutes, plunging my entire apartment into darkness. The issue seems to be capacitive coupling from the bed heater to grounded parts of the printer.
Support advised me to check the wiring order of the AC board, as described in the Wiki. I first didn’t believe that could help, because in Germany we have reversible plugs and I had already tried reversing it before. And I really didn’t want to have to take apart my printer.
To my surprise, after I disassembled my printer, fixed the wiring order, and reassembled it, the problem is actually gone! Lesson learned: Don’t doubt support before trying what they suggest
That being said, I don’t know if the P1P even has the same issue – my X1C is one of the earliest Kickstarter units. The wiring order was fixed in production a little later, AFAIK.
