ᐅ Partially upgrade electrical wiring to current standards?

Hello,

Currently, our electrical system is still protected by Diazed fuses, and the wiring consists of two-core cables. In about 3 years, the wiring throughout the entire house is planned to be replaced.

In 2-3 months, we will be building an extension. Since part of our house is still rented out, we would like to at least wire the extension according to current standards right away. Is this possible? Can the new wiring be integrated into the old system?

Thanks in advance!

Hello,

technically, it is possible BUT

usually, an electrician would warn you against this idea. If you make any changes to such an old electrical system (and I’m not just talking about replacing a socket), then actually EVERYTHING should be brought up to current standards. Especially since you mentioned you only have 2 wires, which means no protective earth conductor... I would definitely want that changed for safety reasons.

So talk to your electrician to see if THEY are willing to turn a blind eye and install a temporary solution.

Based on your description (without knowing exactly what your setup really is), I wouldn’t do it.

If someone touches a live part because there is no grounding, the electrician would definitely reprimand me...

Thank you for your opinion. In principle, I completely agree with you, but since, as I said, we still have tenants, I cannot dismantle the entire house...

That is, of course, possible and even mandatory. It would be completely illogical to build a new extension and then apply the technology standards from 1960 there.
