Earth bonding required in bathroom

[Cocat2517]

Hi,
Doing a little work in the bathroom and I noticed there's no earth bonding. I understand in certain situations it's not required, but not sure if that's the case here or not?

Acrylic bath, metal talt/shower, copper pipe (plastic push fit joints) etc.

Main switch in consumer unit..



Cheers

Can't tell by looking at it.

Might not be required or might be elsewhere.

Your main switch looks like the test button is stuck in.

It's not, I tested it after reading your post and it work, tripped the switch ok, thanks though.

While I'm here, I recently started another topic about adding a third socket in a radial circuit. Cut a long story short.. turns out the MCB for that radial was 40a with 2.5mm² cable, so dangerous. Have replaced MCB with a 20a one as suggest by taylortwocities.

I've now noticed there may be issues with other sockets. I suggested replacing all with 20a mcbs but told no as they are likely to be on a ring main, but I'm not sure they are. Should there be any sockets on a ring main with only one cable connected, or would this mean it's not a ring main but a radial?

Picture of MCB and one of the sockets it's connected to, could this still be a ring main and there 32a MCB is ok?....

That socket could be a spur from the ring, which is allowed.
Or it could be some other unsafe mess.

Ok thanks. Just had a look, there's at least two sockets like this. Got an electrician coming in soon to do a few bits, I'll get him to have a look an confirm what it is and make it safe it need be.

Ok.

Ok now.

It could be a spur. If so a nearby socket or (hidden) junction box could have three cables.
Or it could be the last one on a radial.

I only read the page on ring mains, didn't see this one that deals with spurs... https://www.flameport.com/electric/socket_outlet_circuits/ring_spurs_socket.cs4

Checked, yes both the sockets with one cable are nearby a socket that has three, so a ring with a couple of spurs it would seem. Will be leaving the 32a mcbs in place, as previously advised. Thanks.

You shouldn't be randomly changing circuit breakers. This is all work for a competent Electrician.
