supply tails

[the pict]

I have just mounted a CU in my own home for this years assesment visit, I had some 25mm single insulated unsheathed can I use this to the CU from the henly blocks or must it be the grey sheathed stuff, I cant find it in the bgb but I am sure its there

you can use it if you put in in containment, e.g. plastic trunking.

I would change them to double insulated, looks more professional and one less thing for him to comment on.
