I'll be honest I'm not sure where myself or the client stood inspecting fuses that contained asbestos flashguards behind? (I have to return anyhow so can check)When the fuse carriers are removed are there additional plastic inserts covering live parts very old units never had this provision but "newer" versions did although they can be missing but this was the nature of the dist board. The damaged fuse carriers in my opinion are a Code 2.
If the connection of the earthing conductor is poor then this should attract a Code 2 although very often with TT the conductor is very just often earthing the electrode with the fault path following routes of less impedance.
Judging semi-enclosed fuse element sizes can be difficult if they are clearly not the originals and experience plays a part here. I carry multiple sizes for comparison and if in doubt I just replace them. Do not forget to add the correction factor of 0.725 when assessing current carrying capacity of conductors protected by these fuses.
Asbestos flash guards I tend to Code 3 although strictly speaking they are a health issue as opposed to an electrical problem.
Do you agree that a code 2 would still be present for the user exposed to live conductors upon replacing fuse wires? (Forget damage to the fuses for a minute). However a tool is required to open the cover. Technically no different to removing a faceplate.
Yes I agree, hence the comment about the structural steelwork.
Yes due to the fuses not so certain in operation.
