Frequent Light Bulb Explosions in Bathroom: Electrical Installation Issue?

Hello, I know that the topic has been discussed on the Internet, but I would like to ask. Well, I have such a problem, when I turn on the light in the bathroom, there is a bang and blue vision before my eyes... blown fuse in apartment B16 for the light and the main fuse for the entire apartment in the corridor? The lamp in the bathroom, of course, does not light. All I know is that the bulb is intact and not broken. And now I have a question: what could have happened? For now, I don`t have access to a lamp because the bathroom is dark. I`ve had similar cases like this before, but the bulb broke (exploded) and the fuses were only blown in the apartment, the B16 one for the light, not in the corridor. What could be the reason for this? It may be the fault of the installation, because almost always the bulb in my house explodes, and not, as usual, it goes out or simply burns. I`m just asking the question to find out if it`s normal for this type of bulb to explode and not burn? Could installation be a problem? And what could have happened in the bathroom that made it sound in the corridor? Thank you in advance for your answer and all this fun is with a 100 W filament bulb.

Well, call a good electrician because it`s not normal for bulbs to explode, they just burn out. It`s a miracle that no one has lost an eye because of this.

Are these bulbs from one company? How do these bulbs behave in other places?

This year, 3 bulbs in my rooms have burned out, one in each, and the one in the bathroom, and it always looks the same, I turn on the switch, there`s a bang, a flash... and glass. And today`s case worried me because why did two fuses blow at the same time, in the house and in the corridor? So it didn`t explode this time? Anyway, I`ll check what happened there tomorrow because it`s too dark today and I`d like to turn off the fuses to be sure. If you have any suggestions, please write and I will be happy to talk about it :D

I bought these bulbs from different companies because I thought they were defective, but they don`t all explode in the same way. It may have happened once that the bulb burned out normally :/

Obviously untrue. Unfortunately, this is not uncommon lately, and is facilitated by a closed fixture in the bathroom, which means an increase in the operating temperature of such a bulb. Something loses its elasticity and when the light is turned on, the breakage of the filament causes an electric arc, i.e. current values close to a metallic short circuit.
The only advice is to take care of securing this circuit and periodically check whether the fuse is still functional.
There is no need to call an electrician, it is not the installation`s fault. The course of action after such an event is to replace the bulb with a new one and attach security measures.

This is normal, don`t worry.

Phew, that`s good, because honestly I was starting to worry. And one more question: can blowing the main fuse in the apartment in the corridor at the same time as blowing the fuse in the apartment (B16) indicate that the fuse (B16 in the house) is not working properly or is faulty?

1. indicates a poorly made installation because I don`t believe that you have 2.5 mm2 wires for lighting
2. How is the apartment in the corridor secured?
3.CDN

It proves the lack of selectivity of security measures.

For the manufacturer yes, for the customer no. Unfortunately, this is an intentional action by the manufacturer.

I suspect that these are no longer overcurrent values, but short circuit values. The security response is correct.

Replacing a light bulb is a bit of a stretch. There is rhetoric on the forum about calling an electrician for everything, but let`s not exaggerate. Please buy an energy-saving or good LED lamp and the "problem" will disappear by itself.

Of course, we are talking about short-circuit selectivity, or rather the lack thereof.

Not entirely, I don`t think selectivity has anything to do with it, but the short-circuit current was so high that both fuses tripped.
I once wrote in a topic about the same problem - B10 for lighting and B25 for pre-metering were turned off.

Plug them in, use them and install them, and when you buy the bulb, replace it with a new one, observing health and safety rules... so that no one gets angry :)

As someone already advised, replace it with LED and the problem will be solved.

If there were fuses, there would be no problem with selectivity.

So how do you explain the second sentence of my statement?

Compare the time-current characteristics of circuit breakers and maybe you will come to something yourself.

What I managed to read from both fuses is:
at home - S191 B16,
in the corridor in front of the counter - S191 25A
Below for scientific purposes or as a curiosity I present photos of the bulb, I will add that after replacing it, the light in the bathroom is on, so everything is OK

You mean before the counter?

Here also a curiosity, or rather an answer to problem a
here accessible language for the layman.

Okay, okay... I think that C25 (considered by many on this forum as a bee) would also fly in such a situation ;)

It also looks broken.

So, before the meter, I was thinking about the meter, and I wrote about the fuse

and there is... a switch.

Approx. Enough.
