Today we had NIE turn up to fit a meter in the box to provide a site supply. They refused to fit the meter due to the lack of a TT earth and stated that all site supplies must be TT earthed. This came as a bit of a surprise as I cannot see how a rod stuck in the ground can be anywhere near as safe as the TN-C-S system we have just had installed.
All I can think of is that is is due to the site meter they want to install
Can anyone confirm/explain this requirement ?
