Looks good but I'm going to wait for R2 D2 or C3PO not bb8 he's
Great find. Great price. And if anyone is thinking what the heck is a rcbo. In layman’s terms it provides over load+short circuit+leakage protection, better protection then just having a rcd.

Can it play Crisis?
RCBO, what happens to your droid when you forget to wash him for a couple of weeks.

Just what every DIYer should be playing around with.
These aren’t the droids that you are looking for...
I've got a question, and it might be a bit daft, but they sell different models at different amps. Why wouldn't you just buy the one that handles the most amps? What's the reason for buying a lower amp rcbo?

wiring is thinner on some circuits (such as lighting) having a high current trip would allow more current for a longer time under fault conditions, meanwhile that thin wire is heating up and maybe starting a fire.
Same thing if you have a fault in an appliance... your little phone charger could become a bomb !

This is why we have and need people who have electrical qualifications to do electrical work I don't mean no offence to you personally, and it's great that you asked the question.

A RCBO is both a safety device protecting you from serious electric shock and an overload helping to prevent fire and electric shock. Regarding the later fine tuning the current rating of the RCBO to the load improves the protection believe me you don't want the long answer its hard sums and complicated.
This device is for electricians and serious diy only.

If you want to play with bus bars and RCBOs, best get a move on. Legislation expected soon to effectively ban DIYers from even being able to buy such components.

This is a shocking deal, no wait it's fine it tripped.

Thanks for info its probably for the best.
House wiring is simple and with RCBOs safe (although I've seen a few go pop) but getting it wrong can be deadly. For example a large metal clad office sitting on low wall 3p+n+e only 5 wires an earth fault couldn't trip a 32 amp breaker. Result live building cladding and all. Fortunately a bunch secondary faults raised the alarm.

Thank you for your response, and all the responses to my daft question.

I appreciate how hard the maths can get. It's been nigh on 3 decades since I did a-level maths. I've recently started one of those free online electronics courses, and the maths is already difficult. Going to have to read it all through again, to try to take it in.

I'm just planning for one of those amateur electrical projects that everybody does down in the garage, planning being the key word, but every time I hear about something new, I'm curious. I've been tinkering with Arduinos and 5v and 12v components, and I am reading up, because I'd like to add more serious components in future. (And try not to kill myself) I wondered if this might help prevent that.

No this will look like a dogs dinner they are for fitting into consumer units. Presumably your running from 13amp socket your best bet is a safety plug like Screwfix MASTERPLUG RCD ADAPTOR (63731)
At about £10. Use a 3amp fuse you'll have to try very hard kill yourself with this setup.

Cheers. That's exactly what I'll need. And I happen to have £10 credit on my Screwfix account, which will make it free.
