Separate circuit direct from supply to bypass main CU

[RF Lighting]

I don’t understand why you think you need to connect wires into the main switch or RCD.

As you’ve been advised many times already, you need to employ an electrician to do this work for you.

You have no idea what you are doing and some of your proposals involve working on live wiring which is just downright idiotic.

I rarely discourage people from DIY, but I genuinely fear you are going to end up injuring yourself if you carry on with this project.

To be fair, he says there is an isolator before the CU.

Oh well crack on then

 

[EFLImpudence]

The main live and neutral wires which go into the two RCDs? So I could take the wires from the top of the RCD?

Yes, but the point is that you did not know this.


Anyway, you will have to test an RCBO before you connect the circuit to it so you might just as well get an electrician to do the job.

Yep

Thanks. I’m not planning on putting a RCBO/RCD on the new circuit just a MCB. Don’t want it to trip you see.

No.

You want it to not trip when there is a fault elsewhere in the house.
You DO want it to trip when there is a fault in the door opener itself. Otherwise, you might touch the door and get a shock!

It may also be a legal requirement that there is an RCD.

Great thanks for the guidance. I see that’s a good idea now

Here's a thought - I don't think it has been mentioned, has it?.

What if it is the garage door that causes the tripping?

Thanks. It’s not, good thinking though.

Since I don't like spending money when I don't need to, I would be looking at fitting a RCBO either to reduce tripping or to ensure when it trips the garage door still works.

However I don't have a Eaton consumer unit so could not give a step by step instructions, but to fit one RCBO should not be that expensive, so there are many ways to cure the problem, and it could be with the right test equipment the cure could end up very simple.

So would agree in this case likely better to get some one who can test and do the job without putting anyone in danger. It may also work out cheaper.

How do you know? Just curious, as I've been caught out by this before, as I didn't know how rcds work properly!

 

[MFRacing]

Just getting all the kit ordered I need. Can anyone recommend a nice CU box for me? Seem these part populated ones that seem good value. Not sure weather to go RCD or RCBOs?

If I am reading this right, you asked a question on the forum, you got answers you did not like, so have decided to do your own thing anyway, but would like some one to suggest how best to ignore all you have been told? So my question why did you ever bother starting a thread asking for advice if you have not intention of following any advice given?
