What's the difference between an RCD and an RCBO? - Circuit protection.

Very clear. Thank you!

This I like at the UK regulations: The RCCB/RCBO use only one space place. In Germany all 2pol (L+N) RCCB/RCBO are two space wide, mean need special power bar with L+N. Here use mostly L1+L2+L3+L1 aso. or same L as in UK. We say RCD to a RCCB here. A normal device is a MCB.

very very clear. thanks a lot

great video tutorial,very informative.
thank you for sharing your knowledge.❤️

Great clarity

Hello sir,
Should the outdoor service switch be greater or smaller than the main breaker in the consumer unit?

I'll be so grateful if you would send me back.

Thank you,
Khalid

Very good explanation indeed.Thank you sir !

is its operation based on Kirchhoff Current Law?

Thank you eng joe 4 your great information, really needed to add it to my knowledge.👍😇
Best wishes to u .

Thanks

I just started a new job doing panel building. Your videos help me a lot.

Where is the FE wire (white) of the RCBO?

What about earth leakage circuit breaker? Very confusing.

Clearly and concisely explained. Thank you Joe.

Hi joe, do you have any idea why BS7671 forbids installing RCD's in a TNC system? I am aware that this is not a perfect protection, but in old buildings which don't have any earthing system, the presence of an RCD would be better than not using it.

These rcbo devices create extremely high levels of dirty electricity, in turn creates fibromyalgia increases to the suicide rate, hopefully these devices are phased out in the future

How to identify a rcbo. Please someone explain

What link below??

As a student surveyor this was excellent watch. Thanks

Why havent the engish speaking people a proper name for things??We call them the Group breaker(translated off course) and Alamat.And the box with the group breakers a group breakers box!Almost ever situated right after the frontdoor in a special cupboard with a normal door.Gas and water will also be there.Heated and cold.And of course the Earhtleak breaker.

Same electrical systems different county different ways of doing it 🇺🇸 🇬🇧 very interesting 🤔

Where’s the link?

well explained Joe.Thanks

Is it possible to use one RCD(or RCBO) with one AFDD to secure multiple circuits (6 for example) that are protected with MCBs? Im bit confused with installing AFDD, because its expensive to use on every circuit, but if can use 2 or 3 per board instead of 15 that would be great.. Eu-installation

No the front of them it say test regularly, sparks installs, tests, and fills out the forms that’s the last time that ever gets looked at until something goes wrong, real life. 😃

Great video Joe 👍 thanks

Nice one .. have seen only the rcd fitted to some circuits 😯😯

Hey - hobbyist here with a good understanding of electricity. Will soon be undertaking a home renovation which will include a (professionally installed) new consumer unit etc. Looking at RCBO but noticed that most are single pole rather than dual (like an RCCD) - i.e. an earth to neutral short would trigger the RCBO disconnecting phase but not neutral. Isn't this less than ideal?

Where is this information that you said “ it’s down below for us to click “ ?
I don’t see any !

Nice 👌

The transformer winding polarity on that drawing is wrong
