I want to fit an RCBO into a transformer, when the transformer is not plugged into the supply will the RCBO trip as there is no supply at that time?

110 volt units have a different 3 pin plug. You will need to fit a standard Australian 240volt plug on the cord. Get a sparkie or someone competent to wire it and fit it. The black will be Neutral, the White, active and the green is earth. Make sure the DPDT switch is set to 240 otherwise you will burn it out. I will assume that you are in Australia and using the 110Volt through a step down transformer. You should be able to get an adaptor for the transformer to save having to swap 3 pin plugs every time you want to change voltage supplies.

The mains switch can be bypassed temporarily for testing but it would be better to check the circuit with a multimeter or megger.

Most welders are fitted with a thermal breaker to cut the supply if the transformer becomes too hot and it is possible that device is faulty - follow the wiring and you should find it mounted in contact with the transformer.

Both air cooled and oil cooled welding transformers fitted with a thermal breaker are long lasting and reliable.

some models have a external transformer like power supply. Cable plugs in wall socket goes to power supply transformer, cable from transformer connects to TV with a male female probe type fitting. It appears the power supply is missing.

Were you using the right charger? Just because the plug fits doesn't necessarily mean the current is right. Normal charging voltage is about 5V, not nearly enough to cause a spark, so it doesn't sound good to me. If it's still under warranty (or even if it's not) this may need a trip to tech support

Shorted refrigerant pump or defrost grid.

it could be your heater as soon as it fills the heater is engaged on the neutral side and if your heater is down it will trip your 30 ma rcbo on your board the best way to make sure its your heater at fault is take the back off your machine make sure you are unpluged and you will see the heater terminals there are 2 at the bottom of the drum take the wires off and rap the spade connections wires up in tape turn on your machine on a 90c wash it will fill up and then switch it to a 30c wash but it might l not go though the complete cycle as it cannot heatup depending on how hot your water is if it does not trip anything out you will kwow its the heater let me know if i can help futher

it is getting too hot. possibly from your pump getting plugged with sediment or going out.

sounds like it, unplug the projector remove the lamp put the covers back afterwards and plug it in and switch on. If the electric in the building goes off without the lamp then your projector has a electrical fault that needs sorting. If the electric stays on then the lamp has blown causing a dead short causing fault conditions which will trip the main fuse if it is rcd or rcbo.

is the circuit protected by an rcd/rcbo or a standard mcb as this may be a neutral to earth fault/insulation breaking down...try and get the machine portable appliance tested

Hi There,

The Hor Output transistor is connected to the Line Output Transformer. This transfromer provides a lot of voltages around your TV set but includes the very high voltage to the Picture tube...

These transformers are specially tuned to resonate at a certain frequency,
The Hor output transistor needs to match this frequency....so if the wiring inside the transformer is shorted by "just a bit" the picture will be visible but the transistor is struggling to match the transformer impedance,from the mismatched tuning...so the transistor draws more current from the power supply.. runs hot then burns out...

Usually manufacturers provide a Trip circuit that detects that an overload on the power supply is occuring and cuts the power to the Line output stage ...this is usually detected by a clicking sound within the power supply its called hiccuping.

If some one has altered the correct setting on the power trip circuit then the next thing that happens is the Transistor goes Blooooey like in your case.....

So to save you a lot of money replacing the output transistor
please replace the output transfromer as well next time...

But please... please... re-check the power supply trip circuit to save you a lot more expense in the future....
