There is a question that confused me of which one is the right answer.. According to my notes in the course that the list IN ORDER the test required for the new installation is.. 1) Continuity of earthing conductors *CPC * main bond * Equipotential earthing 2) Continuity of ring final circuit 3) Insulation resistance NOTED that all sensitive equipment must be turn off or unplugged. 4) Polarity test ( -+) FIRST 4 IS ALL DURING DEAD TEST ** AND FOR LIVE TEST 5) Earth electrode test ( Ze ) only for TT 6) Earth loop Impedance test ( Zs) 7) Prospective fault current ( PFC) *PEFC ( between Phase and earth ) *PSCC ( between Phase and neutral ) 8) Functioanl test * RCD 1/2 x - 1 x and 5 X Could anyone please correct me if there is missing or in a wrong order .. I have seen different sequence of testing in new installation... my notes might be in wrong order or maybe your expertise will add more knowledge to me and to the other members in this forum. Thank you all . Lplate [/QUOTE]
