240v on the neutral ??

[Troy Lashmar]

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
Troy

Exactly what testing have you done so far?

surely if you rewired the house, and you are now getting a fault, you should know what it is...

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.
