Create a safe switch that will trip RCD

[Dean Longstaff]

So hi everyone, i have alot of electrical items in my room upstairs. And if anything were to fail i would like a switch that would turn everything in the house off. If i were to have a red emergency stop button (normally open) and connect it to a plug so that the ground wire and neutral connect when the button is pressed, would this trip the RCD in the fuse box? Also would it be safe? If not is there any safe ways of doing this? Thanks

Just put a emergency stop switch before the wiring coming in the room

Work benches and workshops have a emergency button
I guess it's 2P2T normally closed switch

Hi, i know that this would be a more practical solution, but i would rather have the RCD trip the whole home. Would that way i said work? It would be easier to wire also.

Mm sounds like you are trying RCD tripper... I don't think should talk about this as people will try and trip the RCD at work or in shopping
Could trip the RCD with computers hooked up.. If you wanted

It might work some of the time, but there is no guarantee that it will work. And you would want to guarantee the operation of an emergency stop.

Okay, so if i didnt work, or if it did work is it still safe connecting neutral wire to earth wire?

 

[DuaneMHunt1976]

The. Neutral and earth are the same thing at some point in the system
This is a very leading questions

What's the real.reason your RCD.keeps tripping

My RCD is fine, but i would like to make a switch upstairs that would break the circuit (trip the RCD)

 

[DuaneMHunt1976]

Right No don't use a RCD as an emergency stop
It wasn't meant for that.. It's stupid thing to even suggest
It is protection not to be miss used

 

[Dean Longstaff]

Okay. Well it worked when i made a plug connecting neutral and ground before. Just wondering if it were safe.

Generally it is not a sensible or safe thing to do. If the RCD is working correctly then it will detect this fault and operate before it becomes dangerous, but RCDs aren't the most reliable of devices so you may get in to a situation where you are introducing a potentially dangerous fault and making the situation worse.

What exactly is it that makes you think an emergency stop is needed?

 

[DuaneMHunt1976]

No its no safe, keep upsetting the RCD at one point it will die
All sorts of things can happen blowing.. Contacts can weld together and be always open

Does that come with a translation into English?

I think the item you are thinking of is a consumer unit.

 

[Dean Longstaff]

Yes, that is exactly what i mean!
