Can any one tell me if there are any pit falls to look out for when carring out earth loop tests on flat Db and main 3 Pase board on test rig in examGuiness Drink

 
You won't do the loop test at the board (Loop should be at end of all radials, or at each socket on the ring), the boards should have the covers on before you power up.

Make sure you switch over the two way switches and test both strappers on the two way lighting, and test the motor starter at the isolator side.
