Comments advice on report after having Electrical inspection

[Engineer54]

hmmm. came across a job the other week. TN-S with an earth rod as well. think i got a reading of around 0.25ohms.

Council house installations in the early 50's were quite often also given a earth rod or lattice, i know that my parents house was, as well as all the other houses on that estate and an even bigger near-by council house estate. Nothing wrong in doing the same now either, to any TN-S or TNC-S derived systems....

So you now tell us there is an immersion connected to the ring? Why is this not detailed on the PIR and given a code 4 (arguably a code 2 since there is only one ring, especially if this is your primary means of hot water)?
this needs fixing with it's own circuit. Probably less than half a day. If he was intending to do this, it really should be detailed on the PIR and quote.
At this age of property, it's also likely the immersion has no safety cut out - this is a code 2 and a new stat should be fitted (see the guides linked below)

immersion is not actually used as water is now heated by oil fired central heating - didn't even know I had an immersion until he checked electric's - as it was one of three switches I asked him to identify as was hidden in a cupboard and didn't have a clue what it was for

With the reading of that low id have expected it to be a TNCS ,so as ive pointed out in a previouse post he has ticked both Earth rod and suppliers earth so it could be a TNCS with a Rod as has been mentioned , an old TT system that has been upgraded to TNCS and earth rod never removed , or the earth from the immersion etc causing incorrect readings , as i have said we all make mistakes ,but in correct main switch nos RCD values ,cpc sizes when there isnt one mmm way to many 1 or even 2 may be

I queried this and he made a mistake and has sent me an amended report with just electode ticked

Not being funny and i hate with a passion pulling other sparks apart , but if he had made 1 mistake then he should have checked the cert over and over to ensure no other mistakes have been made then he may well have spotted the other errors that have been pointed out , like i said we all make mistakes , i have a tendancy of checking over certs after they have been sent out , and if i spot a mistake no matter how small then i will re issue the certificate as i have said its easy to over look an error or enter a number incorrectly especially if its a PC based soft ware you use to do the certs

35mA RCD is my favourite.....

 

[nickblake]

I would like to know where its installed as the schedual say's its on the ring main (Sockets)as its been tested but the observations say they have no RCD protection

I do think its about time we stopped pulling the guy apart though feel sorry for him think if he's not on the forum he should be not so we can rib him but to help him and try to point him in the direction so he doesnt make any more mistakes , sound like a young inexperiance guy to me , we all need help from time to time i know i do (wife say so any way ) lol

can you explain the problem with this to be in terms I would understand so I can query this with him - thanks!

if you can tell me what I am looking for, I can advise where it is?

agreed, but will ask him to clarify some of the points, once I understand them myself a bit more and have gone through all these replies to get a list of what is wrong on report

RCD's are 30ma not 35ma (not all of them there are other values 100ma 300ma etc ) , what i would do is take note of all the errors pointed out buy the guys and query them all

An RCD is identifiable by a small Button that says press to test on it this could be a different array of colours black red yellow blue orange , on it it should have a number or BSEN 61008 or older types BS4293 and have 30ma written on it with a current rating 60, 80 or 100 amp
