UK Legal Details - Sockets - Where is the requirement for separate socket earths to be linked?

[wilmer000]

I have come across a double socket where the earth terminations aren't linked together - Is this illegal (and what regulation do i look at?) or is it allowed, and I just put the loop-earth in one termination and join the unearthed socket with a length of Earth conductor?

 

[telectrix]

do you mean that there's no manufacturers link between the 2 earth terminals? have you metered across them?

 

[snowhead]

Are these new sockets or already connected?
Are they in a house or Office or commercial setting?

There is no law in the UK that specifies what is described.

where you bin hiding? long time no see. ?

This will be a relatively new 2G socket with two earth terminals, and the OP has discovered it was wired 'old style' with both cpcs into one terminal.
No problem at all.

There should be an internal ling in the SO . See Earthing requirements for the installation of equipment having high protective conductor current "see 7.5 OSG Page 86 explains the whole thing in detail, Regulation 543.7.1.201 and 202 refers

Big Clive has a YouTube video where a cheapy double socket with USB outlets has no link inbetween the two earth terminals. Scary.

Must admit that I've quite often wondered why there are two earth terminals on double sockets which are quite clearly linked. Suppose its quite handy to have the extra one if you are earthing the back box but if you have a RFC with a large number of double sockets, if the CPC's are in the separate terminals you are going to get a slightly higher r2 value plus extra connections with more room for error.

See Post 8?

Trainee question, get to the right aisle.. pg 86 osg might explain something

the reason for 2 terminals is for hi integrity earthing, used a lot with IT equipment with high leakage currents. as he said above , osg pages 86 and 87 explain.
