where you bin hiding? long time no see. ?There is no law in the UK that specifies what is described.
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?
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 refersI 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?
See Post 8?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.
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.Must admit that I've quite often wondered why there are two earth terminals on double sockets which are quite clearly linked.
