Hi,
I am a time served Electrician (industrial) serving my time with British steel,
I am still working for Corus (formerly British steel) as shift Electrical engineer, working on a wide range of equipment and plant.
I have done some domestic wiring over the years, I am now doing a self-build for my family I am doing the wiring and as a result will have some basic questions that will be easily answered by most of the boards members.
As I said I am doing the electrics, and as part of a building notice I do not need to be Part "P" accredited, but still need to provide a commissioning certificate to the building inspector. I have dowloaded a certificate that indicates what tests are required, including earth loop impedance.
Not ever having completed an earth loop impedance test before I decided to have a look into it. The result showed that this needs to be done on an energised system, with a dedicated tester.
I now have a small problem, I have a date for my new supply to be installed, but I have been informed from EDF that they will not connect the meter until second fix is completed and the job signed off.
How can the job be signed off without an earth loop impedance test?
Is there a method of calculating without the need of a dedicated tester?
Regards.,
