Hi all
I have the 2394 practical exam coming up and wanted a little advice on an issue.
Where the installation is split into two parts a three phase board, which supplies a single phase board. When completing the testing sequence should seperate them into db1 and it's test results and db2 and it's test results, or as the second dB is a circuit supplied from the three phase board treat is as a circuit.
My experience would say carry out all tests for dB 1 dead and live and then separately all tests for db2 dead and live, recording on separate sheets. Giving a ze for dB1 and ze for db2
And calculating the zs from this.
Has anyone who recently carried out the testing exam got any input on this, have the exam next week and would really appreciate any input.
Thanks
