Fuse replacement with RCBO?

[hawkinsj]

Perhaps showing a great deal of amateritus however....Can I simply replace a fuse in my main box with an RCBO?
a) Would it fit (at work so don't know what sort of box but it's reasonably new)
b) Any regs I need to know?

thankyou !
John.

Do you really mean "fuse"?

If the maker of the CU makes an RCBO for it then it will fit.

Why do you want to install one?

You need to be aware of Part P.

You should have the ability to test your work. http://www.tlc-direct.co.uk/Book/8.6.3.htm

I am installing an undertile heating system and they recommend an RCD be used.

So rather than just putting an inline RCD (or plug version) I was just wondering whether there was such a thing and whether it made sense to do that as a neater job.

If the manufacturers instructions allow you would be better of fitting this type of FCU/RCD rather than messing about with your consumer unit.

Which is notifiable - see the definition of "special installation" here: Schedule 4.

Did you notify in advance?

Are you using a registered electrician for the work?

An additional regulatory issue - as well as notification and testing, you should (as in eminently sensible and not one single good reason not to) take note of the fact that there's a whole section (3 pages) of requirements for floor heating systems in the Wiring Regulations.
