  Some ascii art.

   load ------ XXX -----  MCB.

  XXX - marks the cut.
  

  Now that I have cut it and TRY to on the switch the
MCB trips*Which still has about 8 metres of cabling
from the MCB to the disconnected point*.The cables
happen to run outside of the house under the soil.

 From my understanding some of the cable must have
gone bad. One of the fuse switch is tied to the house
lights. The house lights work fine BUT when I switch
on the switch to the porch the MCB trips. I must
explain better next time. 

Thanks for the correction. 
John
