@@researchcell I'm wondering if the short circuit and subsequent explosion (melting) caused in the LED light bulb will affect other electrical devices on the same power grid, I heard that the circuit breaker tripped in a split second, but it still doesn't give me the feeling that the high voltage at that moment could How will it affect other electrical appliances?
It is highly unlikely for a short-circuit in a house to affect other devices in the same grid due to the extremely large current delivering capacity of transmission transformers. Also the wires that deliver electricity to your house have some resistance. The maximum affect the other users on the same grid can feel is a slight and temporary reduction in voltage during any such short-circuits.
Yes, Using both Fuse and Circuit Breaker is highly recommended to become fully safe from extreme short-circuit events. Circuit breakers, being mechanical devices, can sometimes fail, especially when they get old. Dust accumulation or rust due to over-humidity can result in a jam, which can trigger a fire if no fuse is present in the series.
Yes, we actually use two fuses, one on live and one on neutral wire and a circuit breaker in series if each wire. in my opinion, this is the best and the safest approach.
When a fuse and mcb have same rating and are in series then fuse is almost always the first one to go. MCBs trippong involve machinical movement which is always slower than a thermal meltdown of a proper alloy fuse.
“Oh no look at the smoke” dude says omg 😂
The smoke was clearly more than my expectation!

Well done experiment 👍🏾
Interesting, I hadnt considered using both

Wow nice video.
What if I use two fuses instead of one fuse and one breaker which is expensive and might fail without warning.

It didn't trip out automatically. was the connection done through mcb or isolator... if mcb then it should trip out automatically..

Whta volt did u used.with this test 220v?
The short-circuit was in a controlled environment and the volts were bellow 110V
