Circuit Breakers

These offer benefits over old fashioned safety fuses, they react faster, and when they trip you just have to reset the switch instead of changing the fuse.

My problem is my flat is getting older and a couple of times circuit breakers tripped and then could not be reset.

I had to call in the electrician to take the power panel apart and connect the power cables to a new Circuit Breaker as this work is beyond my wife's faith in my DIY abilities.

I am surprised there are no plugin type Circuit Breakers so one could just pull out the broken one and stick in a new one instead of changing the cables over. Or maybe they do exist? Does anyone know and what would they recommend to comply with the fussy Swiss regulations?

Re: Circuit Breakers

How old are your current circuit breakers? They last for years - a couple of decades so perhaps they are just on the way out.

If so, you could just get the whole lot of old ones replaced in one go and then leave it at that.

Over 30 years old.

Very easy to change, just 4 connections. Surely you are old enough to have wired a plug in the past. Remember to turn off the power first

I removed this from my fusebox yesterday, it took 5 minutes in total, been thinking about it for a month, I waited for the wife to go shopping It was a remote system to turn on central heating via a phone call, not needed as I fitted smart thermostats so I can adjust each room separately via the internet. The thermostats have between 3 & 5 wires each. The larger rooms only have 3 wires as the third wire switches a relay, the smaller rooms below 5 amps switch directly at the thermostat need 4 wires, the timer has no use anymore with smart control.

Over 30 years old.
Are these over-current circuit breakers or earth leakage types ?
My brother told a tale of a constantly tripping earth leakage circuit breaker. The electrician found the remains of a garden slug which had slithered into a wall socket.
These are normally permanently wired because they should last a long time.

Does not exist (tho in the past we had automatic breakers that would fit in a screwcap). And circuit breakers normally last so long and are so easy and fast to replace that there is no need for such solution. It would just make them more expensive and add more connections and parts to the installation which is to be prevented.

In your case I would order new parts to replace all the old ones yourself, I believe you are old and wise enough to do this in a proper way.

There are some very cheap Chinese ones available for €2-3, which I would avoid. Ones from known brand 'Simmons' cost from €8, LeGrand from €10 sure there are some premium Swiss ones for much more if you look hard enough Prices from France last week.

Yeah, unknown brands for things that are ment to protect my house and my life

I know from Industry that at least these brands are good enough quality and prices do differ.

Emat, AEG, Schneider, Attema, Hager, Eaton, ABB, Siemens LeGrand.

And feel free to order them in Germany, Netherlands or such, they are all the same ones.

And Brands like Singi and many others where you can order them even for under a dollar are of inferior quality.

Re: Circuit Breakers

Thanks for giving me confidence.
I did the job in 5 minutes and most of that was removing the front blanking panel which was held on with some sort of hidden spring clips.
One of the circuit breakers in the panel was unused so I just swopped the two wires from the faulty one to the good one.

It's amazingly easy, you probably saved 200 CHF for that 5 minute job!

One thong I forgot to say is make sure the connections are very tight as a slightly lose connection will lead too a voltage drop & heat build up, it's always something to double check at the end of the job.
