I had an electrician come around to install a new consumer unit,he insisted he can't put the earth on the earth bar but only to neutral bar but this caused the rcd to trip so i removed the earth from the neutral bar for now and all working,i have the model with a spd(surge protection) and worried this should go to earth only.Should i install to example pic 2 or 3 model is pic 1 sorry for the orientation thanks for any info.

Correct routing is:-

• Incoming live to live input of the incomer.
• Incoming neutral to the earth bar and then to the neutral input of the incomer.
• Earth rod to the earth bar.

So, it looks like Piccie No.2 is what you want.

thanks i was worried that the SPD has a link to the earth bar so should the neutral be there,cheers. 

Now people know why they are referred to as sparkies

In this setup the SPD goes L to E (which is also N).

 

I suspect he didn't want to lose face
