Sorry, this again.
Normally I don't ask, but just want opinions on whether my thinking is in line with the majority on these observations I've not come across in a while.
1.
TT system. Ze: 340ohms. Code 2. Question is, what would you define the cutoff point between no code, code 3 and code 2. Personally a code 3 would be not for the result, but if I thought the cable/rod/joint could be protected better etc. Code 2 if Ze higher than 200ohms or significantly higher than I have reason to believe it 'should' be. Is 200ohms the correct figure, and anything above this code 2?
2.
NYY-J/Hi-tuf buried direct in garden to shed. Unknown depth. RCD protected. Leaning towards Code 3 here, but expect some would go Code 2
3.
MICC from suppliers cutout in loft to suppliers cutout under stairs. The pot is visible above the cutout in the loft, with 'basic insulation' visible. FI - with UKPN to further investigate.
4.
Lighting has no cpc within the cable. All Class 2 fittings and plastic switches. Some metal KO boxes are fitted in the wall behind switches. Code 2. Would change to Code 3 if nylon screws fitted.
Cheers
