Your air conditioner may be tripping the breaker immediately when turned on due to an electrical issue, such as a short circuit or overload. It is recommended to have a professional technician inspect and repair the air conditioner to prevent further damage.
push breaker all the way OFF, wait 30 sec, turn breaker back on,
To intentionally trip a breaker in a safe and controlled manner, you can first identify which breaker controls the circuit you want to trip. Then, turn off all devices connected to that circuit. Next, firmly push the breaker switch to the "off" position, which will trip the breaker. Finally, reset the breaker by switching it back to the "on" position once the issue is resolved.
You didn't say what, if anything was on the circuit. If everything is unplugged from the circuit or disconnected from the circuit and breaker still trips then you have a bad breaker or faulty wiring. If you remove all devices from the circuit and it doesn't trip, you need to find out which device causes the breaker to trip by plugging one device in at a time. If the disconnect controls a single device like an air conditioner you would have to turn the power off at the main panel and then physically remove the wires connecting the Air Conditioner to the disconnect. Then turn the power back on and see if the disconnect still trips. Again if it does you have a bad breaker or a short somewhere in the box. If it doesn't trip you have a bad motor whose windings are likely shorted or some other condition that is drawing more than 40 Amps.
Your air conditioner may not turn on due to issues with the thermostat, a tripped circuit breaker, a clogged air filter, or a malfunctioning compressor. It is recommended to check these components and seek professional help if needed.
If you have a burned circuit breaker in your home, it is important to turn off the power to that circuit immediately and contact a licensed electrician to inspect and replace the damaged breaker. Do not attempt to fix or replace the breaker yourself as it can be dangerous.
A circuit breaker is dual function. The only time it will trip is if it senses a fault current that is rated higher than the breaker rating (short circuit). The other trip condition is if the circuit is overloaded and is drawing a current higher than the breaker rating. On breakers that protect motor feeders the breaker has to be rated 250% higher than the motors full load amperage. If the breaker has lots of use and is used for a switch being manually turned off and on will weaken the trip value of the breaker. If you have access to, or know an electrician, a clamp on amp meter on the conductor that the breaker feeds will tell you what is happening. Clamp the line and turn on the load to see exactly what the current is. If, like you say, the breaker is properly rated and the current is within the breaker limits then change out the breaker for a new one.
If your washing machine trips its breaker, first reset it. If it trips again, the issue is likely with the machine. Common causes include an overloaded circuit, a faulty heating element, motor, drain pump, or damaged wiring within the washer. For persistent issues or if you're uncomfortable dealing with electrical components, it's safest to consult a qualified electrician or appliance repair professional.
safehow like the house blows up or something no i thinks its safe and nothing going to break or explode
If the outlet cover was held open by the lights it could be wet. A smal amount of water will cause a GFI to trip. A GFI is a device which makes certain that voltage is not draining away from the two wires, to some OTHER voltage drain, such as a human body or a wet circuit. if above not the answer go to your breaker box and find the breaker that controls that circuit. you will know when you have the right one when the breaker does nothing, not even trip it self. see what else is on that circuit {what else turns off when main breaker is tripped and unplug everything that is on that circuit then turn on the main breaker. try the reset with everything else off if it still trips then its the gfi itself. they go bad often on construction sites [my own personal experience] if it resets properly than one of the other things on that circuit is the culprit. replug or turn them on one at a time. the breaker will trip if its one of these. if not replace the breaker. pretty cheap at lowes or home depot. turn off main breaker when you replace it. lots of luck!!
A stuck compressor contactor. You can turn off the circuit breaker or pull the outdoor disconnect switch to stop it if you have not already done so.
First unplug the TV. Some TVs may still draw current when off, but not enough to cause a breaker to trip. However you still want to make sure you don't fry your TV as you troubleshoot. If there is nothing plugged in to any outlet on the branch circuit and there are no light fixtures the problem is a bad breaker or in the wiring. The ideal is to have an electrician troubleshoot since you can kill yourself while messing with the breaker panel if you don't know what you are doing. Turn breaker off, make sure with a meter that the breaker is no longer hot and remove the wire by unscrewing the lug screw. Do the same for another breaker of the same rating. Hook the first wire removed to the second breaker. Turn on the second breaker. If it doesn't trip the problem is first breaker, and you need to replace it. If the second breaker trips it is the wiring. With the second wire and breaker restored to original connection, leave the first wire disconnected. Measure the resistance with a meter of the disconnected first wire to neutral which are where white wires are connected in panel. If you have everything unplugged there should be an open circuit. If not you need to start disconnecting wires in outlets and fixtures on the branch circuit and determine where the short is. Since breaker stays on for 30 seconds it is likely the breaker since a dead short would trip breaker immediately. The exception would be a short that is causing a current to flow that is very close to the rating of the breaker. If the breaker is good then I suspect you have something plugged in you don't know about.
Your water system is not grounded. Turn the main breaker in your distribution panel to off and ground the water system. If a "hot" wire has come into contact with the plumbing, when you turn the electrical panel main breaker back on a breaker will trip. This will give you the circuit that is at fault and a place to start looking for the short circuit.
