[QUOTE="SPECIAL LOCATION, post: 548251, member: 250"] According to the info on the attached test readings schedule image... The kitchen has a 20A and a 16A radial? AND the quoted max permitted Zs values are NOT the correct values from current BS7671 table 41.3.. They are actually the rule-of-thumb max measured values from the On-Site-Guide... Which is technically incorrect! The garage circuit #8 r1, r2, rn values suggest it is approx 45m (+/-3m) long, does that stack up with the actual size of the garage? Personally I am a bit dubious of those cable installation "reference methods" and the "Insulation resistance" values? An EICR with NO observations at all? That sounds to me like a big pile of smelly stuff that is best avoided, not even poked with a barge-pole!! I think a second opinion would be wise in this situation. [/QUOTE]
