ECR Unsatisfactory

[Guest55]

the following was faound:

1) Outside adaptable box had a large piece missing from the front,
2) Socket Upstairs was damaged showing copper
3) Earth stake was giving a reading of 425 Ohms (Couldnt even find stake if there was one! i predict under the floor which has since been covered)
4) RCD Not functioning properly. Tripped on half reading and during Zs tests even though my meter should prevent this.

1) C2 unless live parts can be touched directly by hand then C1
2) C1
3) C3
4) C2

I would give item 3 a C2 with further investigation as the reading for the earth stake is way to high agree with biff on items 1,2 and 4 though

4) RCD Not functioning properly. ---- C2

Interesting one. If you aint got any RCD's protecting your installation its only a C3 --- unless its forming part of a TT system or for sockets liable for outside use?

I haven't seen anything suggesting a failed RCD should be a C2 but you could well be correct!

Can anyone throw any definitive guidance as to why its a C2 --- not trying to be contentious here for a change, just for my own edification.

As the mention of an earth stake I would of thought it was A TT system Hence the C2

You're right, I knew and gave the answer in my response but didnt read the question correctly!

So to re-phrase my question, if it wasnt a TT system and the RCD failed what would the code be?

Damn, should have engaged brain before posting that question but in my defence I have been drinking and watching a fine Scarlets rugby win!

If the RCD dont work then effectively you aint got RCD protection so all those rule for C2/C3 apply .....

correct

following the general drift of the ESC code guide , C1's are pretty much reserved for items that could cause immediate injury or fire risk.
a faulty rcd doesnt fit that bill really.
in terms of severity , it has "potential" to be a risk rather than be an immediate danger , hence C2
