Shower Consumer Unit Wiring

[Shmeefly]

Hi Everyone

I have fitted my own shower and researched what Consumer unit and RCD's I needed and now I have fitted it all and wired it all up I just wanted to 100% confirm with people in the know such as you guys that I have done it right, I have included a pic so you can see what I have done and just to say the wire coming in from the bottom is from the main consumer unit going into the top of the new RCD.

Thanks

Aside from that does everything look in order ?

as post#2. otherwise looks OK. but give all terminal screws another pinch. they usually settle .

Doesn't look too bad get some earth sleeving though this isn't the States! Also is the cable 10mm2 and how have you installed it?

How many kilowatts is the shower. That looks like 6mm² to me which means the fuse is over the current carrying capacity of the cable. Not good. You would have to check the earth continuity and the Insulation resistance as well as test the RCD and do an Earth Fault Loop Impedance test to confirm it is ok apart from the above.
And I am not sure the top would meet regs as there does not appear to be a gland, could be wrong but then I can't see it.

It's 6mm as the cpc is solid (it's stranded on 10mm)

What is the installation method reference for the cable run ?
What kW rating is the shower ?
How is the distribution cable connected in the main consumer unit ?
Does the top of the enclosure comply with the required IP ratings ?
Why have you selected a C curve MCB ?
Will you be testing this alteration to make sure it is safe, if so how ?
Will you be reporting this work to building control, if so how?

Good observation on the C type @Andy78 I guess as it is old colour cable this was a like for like??

6mm is good for 47A if ref. method C.

Thinking it was probably reference method 101, and he may have a 10.5 kw shower?

Who knows? Unless the op has test kit nobody can say for sure what's going on ........

If the op had a test kit I’m pretty sure the op shouldn’t be asking if it’s ‘ok’ and there wouldn’t be a bare earth
