No earth on installation, WHO is responsible???

ok so if you were to provide your own earth ie rods how many rods would you use or do you keep driving them in until you have a lower enough reading what reading would be acceptable

Minimum of 2 X 5/8'' rods coupled together would always be the minimum number of rods to gain depth and stability. You only need to attain a max of 200 ohms, according to BS7671, but only fools would be happy with such a numbty value!!

Depends what value you obtain with those 2 coupled rods, whether you think it's worth adding another coupled rod or not. Finish off by adding an up front 100mA S type RCD as additional protection to the 30mA RCD/RCBO's....
