client had washing machine eng. called out....who tested the single switced socket??? (w/machine drum fault) and on his rport indicated a higher than acceptable earth loop impedance (254 ohms) as a result im sent to check installation...theres nothing wrong with the installation however a subsequent measurement confirms the figure of 250 ohms...the seperate rccb doesnt trip on an applied fault condition.!! any advice? ps probably going to seek to get the old wired fuse board up graded to a new c/u..:clap:
