This happens quite often. The new counter plug is a split receptacle. There is a tie bar that has to be removed between the red wire and the black wire on the same side of the receptacle. A pair of needle nose pliers will do the job. If you look at the one that was removed you will see where it has been taken out. The way it is wired now you are shorting out the two hot wires and that is why the breaker trips.

What happens when a 20amp device connects to a 30amp receptacle and the power supply fails - will it trip the breaker?
Assuming you are referring to the power supply failing in your 20A device, it could cause the 30A breaker protecting the receptacle to trip. It depends on the mode of failure. It is easy to imagine a condition where a short in the power supply could cause a current in excess of 30A to flow to the device and trip the breaker.
Duplex receptacle circuit given 15 amp breaker 225 amp load?
A 15 amp breaker is not sufficient for a 225 amp load. You would need a breaker that matches the load current, such as a 225 amp breaker. Using a 15 amp breaker for a 225 amp load would cause the breaker to trip immediately due to overcurrent.
Can you run a 30A dryer on a 50A receptacle?
You can always run under a receptacles rating. This just means how much current can be drawn thru the breaker before it will trip.
Why is it good to a ground on a receptacle?
Not only is it good to put a ground on a receptacle it is mandatory by the electrical code rules. The ground is installed to provide a low impedance return to the distribution panel to trip the breaker supplying the circuit in case of a ground fault occurring on the circuit.
Does mcb trip if a short circuit occurs?
Yes, a breaker will trip if there is a short circuit occurring on the breaker's connected load. The breaker will also trip on an overload condition when the current rises above the breakers trip set point.

What do you think would happen if you put a 3A fuse in a plug used for kettle?
I know what would happen. The three amp fuse would blow. Any device that is plugged into a receptacle with out having sufficient resistance to limit the current flow will dead short the circuit and cause the breaker that feeds the circuit to trip. In this case the fuse being of a lower rating that the feed breaker the fuse will blow without tripping the receptacle's feed breaker.
Can you use two 15 amp single pole breakers in place of a double pole 30 amp breaker?
No, you cannot use two separate 15 amp single pole breakers in place of a double pole 30 amp breaker. A double pole breaker is designed to simultaneously disconnect both circuit conductors, whereas using two single pole breakers would not provide the necessary protection for the circuit. It is important to use the correct size and type of breaker as specified by the electrical code for safety and functionality.
Why would plugging in an AC unit in a wall receptacle cause the fuse to blow or breaker to trip?
Is the receptacle a 110 or a 220 outlet? If it's a 110, it needs to be a 220. Are there other appliances, lights, etc. wired on the same outlet? If so, you may have to re-wire so that no other appliances, lights, etc. are wired into the same breaker. Usually the larger appliances such as air conditioners, central heat systems are wired to a separate breaker or fuse.
How do you find the circuit breaker switch that controls a damaged outlet?
If the damaged receptacle faulted the breaker would have tripped. All that needs to be done is turn the breaker to the full off position. This will take the breaker out of the trip position and the circuit is truly off. It should not be hard to find the faulted receptacle as it will have some major damage to it and that is what made it short out in the first place. Change it out for a new one and test the circuit by plugging a lamp into it to confirm that the wiring was done properly. When removing the faulted receptacle check the wire colours and positions and install the new one with the exactly the same wire position configuration. If the damaged receptacle is just worn out and they do wear out, plug a light fixture into the worn receptacle. With the lamp turned on start switching the individual breakers off in the distribution panel one at a time. Just switch the breaker off and on and see if the lamp goes out and comes back on. You will probably need help with this part if you can not see the lamp from the distribution panel. When you locate the breaker that controls the lamp, leave it off and change out the receptacle just as they were connected to the old worn out one.
Can a breaker be bad and not trip when there is an electrical overload?
Yes, a breaker can be faulty and fail to trip when there is an electrical overload.
Why would a GFCI trip with no load connected?
Are any of the outlets OUTDOORS? If so, and if an outlet is getting wet, it will trip the GFIC immediately. If that's not it, unplug everything, reset the GFI and see what happens. If it still trips, make certain that the wires aren't getting wet somewhere. If THAT'S not helpful, replace the GFI.
