How is pulling out an oven, which requires a degree of dismantling; or lifting a hob; or indeed pulling out any other item of fitted kitchen appliances, consistent with GN3 para 3.8.1 Scope: "... The inspection is carried out without taking apart or dismantling equipment as far as possible."?

Is undoing a few screws in woodwork, that are only there to stop the oven sliding forward when opening the oven door, 'dismantling equipment'? Arguably not, and I would rather pull it out to see if there's some dodgy wiring in behind, than leave it due to an ambiguous guidance statement/term - and it's not doing harm, quite the opposite. Would you not take the tube out of a florescent fitting, and the lid off, to see if there's thermal damage to the wiring, because it's dismantling equipment?

No because that is not part of the fixed wiring. However, I would probably need to take it apart if I needed to measure Zs at the luminaire.

 

Sorry, do you mean the flourescent is not part of the fixed wiring? Presumably you wouldn't open the door/lid of a rotary switch disconnector to have a look inside either because it's dismantling - which isn't much different from removing the flpurescent lid. I'm not trying to be contrary, just determine where the boundary is between what is reasonable to open up to inspect, and when it's not. 


Also, according to this article in the PE mag, https://professional-electrician.com/technical/determining-zs-for-a-lighting-circuit/ reg 14 of the EWR 1989, prohibits us from measuring Zs at e.g. Light fittings because it's unnecessarily working live - we have to measure r1+r2 and add Ze instead to determine  Zs
