socket

[Buzz-light-bulb]

Little scenario for you all.

I've been doing an eicr today and come across a double socket wired as a radial on a 2.5mm t-e, which is protected by a 32 amp rcbo.
Technically this cannot overload as the cable can withstand 27 amp ref method c. Unless mr DIY comes along and starts adding new sockets which I am not responsible for so my question is would you leave it

You need to be careful there or that 6A breaker you put in might keep tripping every time they put the shower on .......

Lol :lol:

IF overload and thermal constraint limitations are met, it complies with BS7671 so no code, no comment

I think there's a danger of confusing "Is this an absolute top-notch covered-all-the-bases, cable-cannot-be-rogered-by-incompetent-additions-or-rogue-equipment design?" with "Does it actually require improvement and if so on what grounds, preferably supported by the regs?"

In regards to the OP, had anyone apart from HHD read reg 434.2.1? If no do so that will tell you where you may place a OCPD?.

Dave, you cannot load the CIRCUIT any higher than 13A, unless you are abusing the plug and socket system

Exactly, so therefor you have to create a circuit to prevent this, IMO it's down to good workmanship and pride in your work.!!

You know what i was getting at badged

I do but I like some banter and fun between all the technical crap!

You have to mate.... to many regs book eaters !!

Then again we are told to flag up "Some circuits which require RCD protection under the current regs have none" as a C3...does that require​ improvement?...my brain hurts.

Or 433.3.1 for why you might not even need one .....

434.2.1 discusses fault current - that is met by the 1.5 cpc in this instance

deleted, Badged already said it!

No, you don't, where do you want to stop babysitting the stupid who abuse an electrical system? Let's pull the main fuse in case somebody abuses the tails to the board and decides to splice a light for his shed into it.

I take huge pride in my work, like I said before I would not go out of my way to do something like this. But! If I saw a busbar chamber and 2.5mm straight from the busbar to a double socket below I would not code it on a EICR. The 2.5mm CANNOT be overloaded!

 

[jamie-spark]

The cable would be protected against overload - IF

It only served one piece of equipment at the end of it's run and nothing on the way, so you can't have a radial with 3 double sockets on it obviously.

Obviously you can't have a 16A socket at the end because these have no fuse system, but you could have one 13A socket or one switch fuse (fused appropriately for the cable)


I am not saying I go out of my way to install like this, I use an appropriate sized MCB at the origin like anyone else, but technically you don't have to.

Do you think you can't have a 16 a socket outlet on a 32a mcb ?

Having reminded myself that a C3 means improvement required, I now agree, no code is appropriate. I would say maybe a comment but I don't think the EICR form lends itself well to comments that aren't tied to codes (observations section requires a code for any observation made). Amazing what you can learn from civilised discussion. Cheers.

does it now...


hopeless....

Nick......:

you`v no business carrying out condition reports at this present time.

so please dont.

 

[NickD]

does it now...

It does according to GN3 but the consensus and logic is it should say recommended as per the model forms.
