With lights though you could surely run the whole light circuit - being it would normally be a 6 amp mcb through a fuse rcd spur with a 5 amp fuse in it? unlikely to exceed 5 amp on most modern light circuits. Could mount it on wall next to consumer unit. just dont forget your nice new 18th edition testing sticker that has to some how fit on the said rcd spur.Thanks - just had a read of it ... Just thinking of a hypothetical job to add lights. Existing board has no RCD for light circuits, like to add RCD but can't because no OE available, so now need a CU change ... "but I just want to change my kitchen pendant to 4 downlights" says owner.
Yes.agree spin, but does note 2 mean that you can fit a different make of device as long as the OM has OK'd it's use in their CU/DB?
FWIW that's how I read it too. I just think it might be unlikely, as I take it the OM would be responsible and the new company makes the sale.agree spin, but does note 2 mean that you can fit a different make of device as long as the OM has OK'd it's use in their CU/DB?
This is correct and has been in the LAW of the land for many years, but electricians seem to believe that they are above compliance with the law of the land in which they live and work.From what I understand, the new prohibition applies to all DBs and similar switch gear within the BS EN 61439 series.
Installing a component which was not included in with the type testing would make the installer the manufacturer and thus responsible for ensuring conformity with the standard.
2% you reckon it's that high? For me this stupid change just shows how out of touch the people who dream up these things are, that they actually think that ANYONE tests their RCD's. Come on lets be honest, how many of you lot test yours regularly??the one i think customers will not like is the requirement for notices for all rcd's even ones not at the board, as i understand it a rcd spur will now need a sticker telling them to test etc... either the writing will be so small it cant be read or you put a picture frame on the wall next to it? as soon as you are out the door they will remove it in any case.
I would be surprised if more than 2% of people ever actually test the rcds as per the notices.
But a control panel with a variable speed drive, contactors etc is not a distribution board. It is not covered by BS7671.From what I understand, the new prohibition applies to all DBs and similar switch gear within the BS EN 61439 series.

You would get more people pushing it if you changed the label to read "Under no circumstances attempt to push the Test button on the RCD"I've never met anyone who uses the RCD test button as per the sticker. I have a little safety chat with folks before leaving and I'm pretty sure no one I've spoken to has ever pressed the test button.
There is one or two jobs worth at the IEE. I suspect many brands of MCBs and RCDs come of the same production line, it's known as badge engineering.pretty much as the title says ....
For me it’s a txss up between the regulation about no mixing makes or mcbs or rcbos - but what if they are identical except for the name or logo
Eg lewden and control gear
AND
the design limit of 30% earth leakage on circuits with rcbo or rcds - how can this be tested / checked and what happens when people move in a new build and plug in all sorts or carp accessories
Next!
Yes. Respectively, it is impossible to create a set of standards that everyone is happy with and have no errors. On the same principal, we have courts and Judges to decide on points of law. Often, with hindsight, they can get decisions wrong.pretty much as the title says ....

This regulation will hopefully stop bodgers from sticking/forcing any random breaker into consumer units.
It’s not that a competent Electrician can or cannot make that call, it’s that the competent Electrician will now have to state the CU/DB complies with the BS EN 61439 series standard.Does it really need a competent electrician to be able to tell if a particular MCB will physically fit onto a DIN rail populated with --- other type(s)?? As for stipulating that they all have to be of the same make/brand/manufacturer, I am sorry that is just b$$locks.
Oh OK. Well that's easy enough.It’s not that a competent Electrician can or cannot make that call, it’s that the competent Electrician will now have to state the CU/DB complies with the BS EN 61439 series standard.
