Problem on job with bungalow

[axel132132]

Hi

I have an issue at a bungalow im working at, there is a fault

All the sockets are on a ring, when i plug something in the living room it trips the RCD plug it into any other sockets it dosent trip the RCD

The board is MAIN SWITCH RCD

Cheers

Faulty skt then ?

 

[telectrix]

check the living room sockets. suspect a N/E reversal.

I took one of the socket fronts off in living room, and it all looked fine whilst socket front was off plugged in and tripped cheers

Please answer the bit in Red how have you established this ?

Change socket and re test

 

[telectrix]

used to be a good code 3 on the old PIRs..... further investigation required.

 

[axel132132]

not established there all on a ring (Havent taken every socket off) but there all on one circuit

 

[Guest55]

The question is..
How long has it been tripping ?

 

[axel132132]

randomly for a few months apparently

 

[telectrix]

when was it's last fix?

 

[Jimmy Boy]

not established there all on a ring (Havent taken every socket off) but there all on one circuit

Then pull the two pair and cpc's out the board and do the testing sequence this may lead you to a conclusion..

Hmmm
maybe test rcd as well on next visit.

I think he should go for the testing of the circuit Biff to check for the usual as well as and before the suspect RCD what you reckon ?

Still think its faulty skt if no tripping anywhere else.
will only take 2 mins to prove / disprove

 

[axel132132]

Yeh will change socket and megger old socket at back to check if its shorted anywere thanks for help hopefully its socket and will save me some time :24:

 

[telectrix]

is it only 1 socket that it trips on, or all the sockets in the room?

 

[axel132132]

All the sockets in living room only, all other rooms are fine its bizzaare

 

[topquark]

All the sockets in living room only, all other rooms are fine its bizzaare

Then it's prob the socket feeding and next outside the lounge that has a N/E reversal (most unlikely that they're all faulty in the one room).

 

[Guest55]

is it only 1 socket that it trips on, or all the sockets in the room?

If its all the sockets in the lounge i wouldnt be surprised if they were on some sort of radial / branch ?
the ones i've found often have a damp / rusty JB nearby.
