Fuse board tripping

[Electrician1]

I installed a new electric point the other day, used a fuse spur, and put it into a spare breaker on the DB, when I went to switch it on, the DB tripped. I can not figure out why, if the spur was faulty would the breaker not just trip. What have I missed? Thanks.

What were your test results ?

What device is it that trips ?

You have a split load board and you connected the neutral to the wrong bar.

If it is. you will be a bit

Thanks, but Netural, Earth and Line are in the correct positions, this is why I can not figure out why its tripping!!!

Well??

When you say the DB tripped I assume you mean distribution board?
If so, is it an RCD main switch that tripped?

 

[Electrician1]

yes its the RCD side that trips, but it is just from a standard install of a single socket through a spur into the DB, I even tried piggy backing it onto the downstairs socket circuit, but it tripped the board as well!!!

What were your test results for the new circuit?

Goodness, it's a bit sad when a single added spur can't be fault found.

Assumption (correct I hope) is that the circuit worked before you added the spur.

So 'something' you've added on is causing the issue.

What have you added on ? Some cable (could it be faulty) and a socket (could it be faulty).

You say you replicated the fault on another circuit (grd flr ring) and it repeats.
So what's the LCD ?

The socket or the installer making a mistake. I'd like to think it's not human error, so have you tried another socket ?

Also...........

When you say tripped the RCD, is that when a appliance or device is plugged in to the new spur socket or when the fuse / mcb is turned on post the work (and not with an appliance or device in socket) ?



Is the circuit you've attempted the work on been tested ?

It sounds like a new circuit - a radial supplying a FCU.

I installed a new electric point the other day, used a fuse spur, and put it into a spare breaker on the DB,

and put it into a spare breaker on the DB,

A new circuit is notifiable under Part P.

Can you post a pic of the CU? It does sound like what Steve said above. Either that or the cable is damaged or the current using equipment has a fault.
