why am i finding 240v on the neutral ?? we rewired the power in a house and upgraded the consumer unit but when the RCD's are connected they trip different mcb's. when testing we found 240v on the neutral.... when you take away the RCD's everything is fine. we have changed the main switch and still have the problem. any suggestions as its getting very frustrating now.
many thanks

Priceless.
 
enlighten me then.... we done a rewire of the sockets only all tested fine but when we installed the rcds they kept tripping also sometimes the trip switch wouldnt work but when you remove one of the neutrals on the the bar the test button works.
using a british genrel consumer unit with 4 neutrals going off to the 2 bars...
as soon as you put one of the neutrals on the bar...bang, trips again ??
 
possibilities.

1. you wired tails the wrong way round.

2. supply neutral is missing, call the A team.

3. some other cock-up. call dynamo, magician impossible.

Pay your local sparks to sort it , its not a DIY thing you've done.
 
Exactly what testing have you done so far?

Wiring things up and removing bits and pieces when it all goes 'bang' isn't testing. I'll ask one more time so please answer before I close the thread.

Tell us the tests you did one by one and the results you got for each test.
 
DIY PME. it gets worse!!!!! first you've either got a neutral in the wrong hole, or a shared neutral, and the |DNO gestapo will be round for mucking about with their gear.
