Separate bathroom circuit

[MaintenanceSpark]

Hi guys.

I'm a Trainee Maintenance Electrician so please excuse my ignorance on bathroom wiring etc.

After reading this forum and watching youtube (Artisan, Bundy, CRJ Electrical) I've learnt that my bathroom should be RCD protected but the problem I have is that none of my lights in my house are RCD protected and they're all on the same 6A MCB.

My bathroom has 4 downlights, an inline fan with isolator above the door and a shaver point. After reading the forum I can see why the sparky that wired my bathroom didn't put the MCB on the RCD side as he could have inherited faults like borrowed neutrals (if I've read correctly that is). I'm guessing it's not 100% safe to leave like that? So....

My plan is; Run a whole new bathroom circuit from the RCD side of my CU (1 spare way left). I have drawn a diagram, albeit not that great. I'm hoping it makes sense to someone? Hopefully I'm on the right track?

Thanks very much.

You are correct in the fact that bathrooms need RCD protection.

I have RCD protection on my bathroom as I installed a new consumer unit

What consumer unit do you have?
Can you get an RCBO for it?

This may ba easier

Thank you for the reply.

I think a new consumer unit will be the way to go in the future when I gain the skill set.

My consumer unit is a 10 way Steeple (plastic).

I haven't actually checked if I can get an RCBO for it. I'll ring the wholesalers we use at work tomorrow and see if they stock one.

Would every light in the house be ok on an RCBO or would I have problems like the RCD with inherited faults?

Thanks again.

You should test the circuit to identify any faults and then fix them as part of fitting an RCD to the circuit.

Why you wouldn't fit RCD's in your own home is beyond me, if you are going to take precautions to protect anyone's life then it should be your own!

Thank you for your reply Dave.

When I get the experience of testing & fault finding that's exactly what I plan to do. I was just looking at a way to get a little bit of protection in the mean time.

I agree and that's what I'm trying to do. That's why I thought about a separate bathroom circuit to begin with, to get the bathroom to a standard and then work on the rest of the lighting circuit as I gain the skill set.
