May i use a single insulated copper wire - HO7V-U to make my home
instalation. If i can - what ampacity can i give to this circuit if
cable is sealed
in the wall and run together with other cables of the same type.I dont
know if that type of core is suitable for sealing in the wall.The
longest distance will be 30 m and the highest ambient temp 40 C. If
someone knows please give me advice!

From what I can see that only comes in 1.0mm and 1.5mm, and must be used
in conduit or trunking. Why can't you buy some proper cable?

it is 4mm.

I already have this core .Can I use it or not?it is PVC insulated rated
70C.

Not just buried directly in the wall on its own.

You can use single PVC in a conduit or twin/earth PVC sheathed cable.

Interesting job lot of cable you've been given in the last week! This
single core stuff and the 4-core insulated. Interesting surprises no
doubt for whoever next who comes to look at your electrics. I'd try and
get someone experienced to appraise your work if I were you. (keep
asking questions though)

Might I recommend a copy of this:

It will answer many of these questions and more.

There is much more to designing a home electrical circuit than the questions
you are asking. I'm afraid to say that under no circumstances would you be
regarded as a competent person to design or install an electrical
installation. You should either employ an electrician, do a full design and
installation training course, or not use electricity.

Remember, it's what you don't know that you don't know that will kill you.
And believe me, it WILL kill you if you attempt to proceed with your current
level of knowledge.

The idea that you could select protective devices in order to match the
prospective fault current and earth loop impedence dependent on whether you
are using TN-S, TN-C-S or TT earthing systems is laughable. I doubt you know
what any of these concepts even are. Until you do, you simply can't design
an electrical system.

You might be able to find an electrician who will design the system for you
and let you do the donkey work of running the cables. They will then return
to connect it up and test. However, they won't let you install old cable out
of a skip. They will specify which cable to use and you will use it. If you
can't afford the correct cable, but can afford to kill yourself and your
loved ones, then no-one can help you.

I agree the OP shouldnt do it.

For the sake of pedantry, I think the dangers, while perfectly real,
are maybe exaggerated a little.

I've seen worse though, I still remember visiting a large industrial
building where the (low power) machines were all connected to bits of
scrap cable/bell wire/ flex joined and strung overhead. How anyone
could think that was a remotely sensible idea I'll never know.

To the OP: suggest you spend a while reading here and laerning about
the issues involved, and how to do it, before you do anything. Wiring
your house in 1.5mm singles wouldnt be the best option. Where did you
pick it up, France? Last I remember they were still using 1A speaker
flex for mains.
