I replaced a fuse box last week and when i did the earth loop on the circuits it came up with around 114-ohms yet the ZE was only 0.75-ohm can anyone explain this

i assume he means england and wales. part p does not apply in scotland, southern ireland, outer mongolia, kazeckstan, '''''''''''''''
it is a tns system and i tested at the db on just the main earth and the sheath of the supply and reading was the same 0.75ohm. the only odd thing about it was there was some damage to the sheath of the supply and the original earth clamp had signs of arcing perhaps a previous fault and a loose clamp but still came up with a ok reading with a new clamp.
asked several electricians i used to work with and non of them could give me answer as what could be causing the high reading.[/QUOT
Who fitted the new clamp and what sort did they fit????
