Spanish wiring regs: the basics

[LouiseSJPP]

I'm assessing the extent of the work needed for a renovation project which has been recently, but I suspect poorly, re-wired. I'm not an electrician: I am, or was, a chartered engineer, so I should be able to work my way through this and evaluate the state, but I would love a bit of help to make sure I'm getting it right.
I'm looking at ITC BT 25. Is the right document to work from?

There must a Spanish wiring regs book you can down load somewhere ?

Not if it's under the control of the Spanish Electrical Mafia, ,,

REBT is the applicable standard in Spain - however there are several members on here who live/work in Spain so hopefully someone can chip in fairly soon with domestic stuff.

If its anything like the Greek wiring then its pretty much do what ever you want

Yeah, I've got that. If ever I can't sleep, I could browse through it!

Adding to my question: it seems what can go on each bank is defined. The C1 to C5 set up only allows 20 sockets. I hate not having enough sockets. If I want to go for the higher electrification option, and add a second bank for another twenty, defined as C7, do I have to add in C6, extra lights? I don't need them, but if there are more than five banks, must the sixth be lighting and not the extra socket bank?

I have some limited experience of Spanish electrics. I have posted many dodgy pics of dubious installations, some of them very funny, some a bit dire...it's not unusual to see outside lights run in bell-wire with choc-block connectors run over gardens and open to the elements. However, the electricians I have had in my house there have been very professional, (except they use wire-nuts!) and they do not charge much either.
All circuits are radials. That's good, in my opinion, and it's all singles run in conduits buried in the hollow block walls, with access plates at recessed JBs in every room.
It's true that many circuits can be a bit haphazard, but the internal wiring is generally good. My place has a 12-way CU, and it's a small, 2 bed apartment, with separate radials for washing machine, hob, kitchen sockets, other sockets, water heater (immerser) lighting (split over 2 circuits) water pump, main switch and "differential"...
The electricians turn up same-day, charge about €17/hour (last bill I had was 5 years ago, so may be more now) and do a good job...and don't send their bills in for months!
However...many homes have a very limited supply, so 100A is rare in apartments, thus if you want a big supply you may have to wait, or not get it at all, due to unavailability on the network.
I asked for a bigger supply some 10 years ago, and the supplier Gesa_Endesa, insisted that I had to install heavier incoming cables and a new CU. That was done...the supply incomers are in conduit under the concrete and tiled floors, but they pulled in a new supply in less than a day.
I guess, in summary, the Spanish do have many old supply issues and many, many dodgy bits...but they have modernised a huge amount recently, so I would be happy to work on their systems should the need arise.
My "tame" electrician always gets a box of Wagos from me when I call him...he loves them!
Good electricians...dodgy networks...but improving all the time. It's a great place to ply one's profession...new installations are inventive and serviceable, and they are bang up to date in many ways...just a bit amateur when it comes to outside work.
