Issue with Triton Planer - Circuit Breaker Tripping

Good video

I am running out of basic replies so maybe others with more knowledge of motors may be able to help further.

Have you changed the brushes you mentioned yet as it looks as if they are at the belt end of the motor and with the spark nearby they could be the problem.

I changed the brushes and blades; now I've reassembled it all. In a little while, I'll try to operate it with another extension cord. Maybe this could be the issue.

nothing doesn't work keep disconnecting the life saver. A friend of mine lent me a similar planer and it works great on the same socket at my house

If the start switch operates like a NVR switch, ie it latches on, then the switch may not be holding in or its relay is not latching closed.
So there will be power at the switch terminals on the input, but not coming out of it if its a built in relay/latching switch. As it may be arcing or spiking or grounding ro earth, hence causing breaker to trip.

If power is coming from switch when pressed in, then there may be a remote relay, if a remote relay, you would need to trace the wiring from switch to the relay, then test on the output side of relay. It may show power for a short moment then no power, in which case that's likely the fault.

If that's all OK then see next post.

You could try disconnecting the output from the on switch. Then press switch, if the switch is faulty, then it will trip the breaker.
If not, reconnect, and trace switch output wiring to next item and disconnect that and try again, you could keep doing till breaker trips then that next item is your fault area.

Is it a capacitor start motor? If so a new capacitor may solve this issue

Hi, if I understand correctly, I should disconnect the power wires from the switch and try exclusion to determine which wire might be faulty. I get it, but I admit my ignorance in electrical matters; if I disconnect the wires from the switch, the planer won't turn on anymore because the wires won't be connected. I tried to check with a tester if there's any broken wire, but so far, all the visible wires seem intact. I'm losing hope; I can't find a shop here in Leicester that can fix these tools.

Yes the planer won't turn on. But testing this way will check what causes the breaker to trip at each step.

Any electrician would be able to test and trace what is causing the fault. Then you may be able to change the faulty part yourself.

Did you get anywhere with this Marco? My machine had started doing the same thing, it has had little use in general and only reasonable cause (for me) was storage in a basement (high humidity/damp). It worked fine for a short period on getting it out, but then tripped every single time as you described.

I stripped the whole thing down looking for a fault, and saw sparking at the commutator which did not seem to always be coincident with the RCD tripping. I reassembled it, turning on at each small change to the assembly, and thought it was shorting to the frame (via the belt tensioning bolt). I tested that theory by making a washer from insulating material (left over epdf rubber roof sheet) but it still tripped. Then on reassembly again (without the washer) it has been fine. I planed some lengths of wood and then it tripped again on a wide board. This time the RCD was reset and planing recommenced without any issue.

I do wonder if the issue was storage in damp conditions and it just happened to have sufficient time to dry out by the time I finished troubleshooting it. I intend to give it another go soon and have stored it in our kitchen conservatory since the previous issues.
