The fuse (or circuit breaker) rating has been exceeded. I'm assuming you do NOT have the AC unit connected to a dedicated circuit. Lets say you have a 15 amp circuit breaker and the AC unit draws 12 amps and other items on the same circuit draw an additional 5 amps. The total amp draw of 17 amps exceeds the circuit design capacity; so the breaker trips to prevent an electrical fire. If you have old style fuses, NEVER EVER replace a fuse with a higher rated one! I'm sure you'd have problems with your homeowners insurance paying out when your house burns down. Have an electrician run a new dedicated circuit for the AC unit and you should be good to go.

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.


Can you use a 6A 250v fast blow fuse instead of a 6.3A 250v fast blow in a 250 volt amplifier?

You can it will be safe and no damage will result. However it will blow sooner than the intended fuse would, so the amplifier will no longer have its full normal operating range.


Can you put a 15 amp fuse in an electric fire plug?

I would say no as it could blow and if majorly can damage the plug and can be expensive to repair


Would static electricity be the cause of a ceiling light continuing to blow a fuse?

No. There is an excessive current draw, possibly in the form of a short circuit. Get an electrician to check it and fix it before you set fire to house.


Will the fuse blow as shown in the link in this equipment?

The Related Link shows a transformer inside a metal cabinet, supplied with 120VAC protected by a fuse and the standard neutral connection back to the supply. There is a ground connection from the supply to ground, but there is no ground connection shown for the metal cabinet.The question asks, if the (fused) hot side of the transformer shorts to the metal cabinet, will the fuse blow?The answer depends on whether or not the metal cabinet is grounded.If it is not grounded, as implied in the diagram, then the fuse will not blow, because there is no circuit formed to do so. Additionally, AND MORE CRITICALLY, this would energize the metal cabinet, creating an electrocution hazard.However, it must be noted that per the NEC (US) and most probably any other country's electrical code, such a metal cabinet MUST be grounded.IF, AND ONLY IF, the metal cabinet is grounded, then the fuse will blow, due to the additional fact that neutral and ground are connected together at the distribution panel (again, by code), and again, at the service entrance, and this will form a high current circuit sufficient to blow the fuse and prevent an electrocution hazard.FYI - If I encountered such an ungrounded condition in a metal cabinet, I would do everything in my power to cause the installing electrician to lose his or her license. Additionally, if this caused an electrocution (whether fatal or not) I would sue said electrician for everything they were worth, and I would probably win, even though that would not bring back the person that died. This type of malfeasance should not and cannot be tolerated.

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.
