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.

Can you put a 120 v receptacle on a 240 v circuit breaker?
No, the electrical insulation rating of a 15 amp duplex receptacle is only rated at 130 volts. The 15 amp 240 volt receptacle is rated at 250 volts. The 240 volt receptacle also has a tandem pin configuration instead of the parallel configuration of the 120 volt device. The different pin configuration is so that a 120 volt electrical device can not be plugged into a 240 voltage receptacle.
Connecting a 30 amp device to a 20 amp receptacle does it violate NEC?
If the device draws 30A it will blow the 20A breaker. It is immaterial if it violates the National Electric Code because it is not a practicle thing to do and unsafe as well.
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.
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.
What is use of neutral in a wall receptacle?
The neutral in a receptacle is the return conductor to complete the circuit back to the distribution panel. When a device is plugged into the receptacle this completes the circuit and allows the current to flow and the device to operate.
A GFCI device in a breaker is intended to?
A GFCI device in a breaker is intended to trip the breaker open when a ground fault is sensed in the circuit that the breaker is protecting.
Can duplex oulet have one dedicated outlet?
Answer for USA, Canada and countries running a 60 Hertz supply service.Yes, if it is connected with a three wire circuit such as kitchen counter receptacles. In this case both top and bottom of the duplex receptacle are dedicated circuits. An example of a duplex receptacle being the only device in the circuit from a 15 amp breaker is the receptacle for a microwave oven.
Is a 110 volt electric receptacle the same as 120 volt receptacle?
Yes, the rating on the receptacle is the maximum amount of voltage that is legally allowed to be applied to the device.
Can you use a 60 amp breaker with a 50 amp overcurrent device?
A 50 amp breaker is an overcurent device.
When installing a circuit breaker do you size the breaker to correct wire size or the device its controlling?
When installing a circuit breaker, you size the breaker based on the wire size. The breaker should be matched to the ampacity of the wire to ensure proper protection against overloads and short circuits. The device being controlled by the breaker is not a determining factor in sizing the breaker.
How do I convert existing 3 wire 220 volt 20 amp breaker wire system to 110 volt from the box to the recepticle?
Assuming there is no neutral: 1) Turn off the breaker. 2) Disconnect 1 of the 2 hot wires from the breaker and connect it to the neutral bar (Recommend phase taping the wire white :) ) Remember which wire you used as the neutral, in a home you will most likely have a black and a red. I would keep the black hot, and phase tape the red wire white. If it's not long enough you can wire nut another white wire onto it to make it reach the neutral bar. 3) Leave the breaker OFF, at the receptacle, change it to a 120 volt receptacle. Take the wire you made the neutral, and connect it to the white screw on the 120 v receptacle, and take the black to the hot. Ground to the ground screw. Make sure you phase tape the red wire at the receptacle white as well. 4) turn the breaker on 5) test the receptacle with a meter or receptacle testing device for correct wiring.
What device is used as a form of safety device in an electrical circuit?
A fuse or circuit breaker will fit this description.
