New house in Portugal

[MylesOD]

Hi,
my friend has got a new house in Portugal, it has no mains to it yet but will do shortly. They are supplying a 15A supply. Can the instillation be wired in twin+earth etc. I can't seem to find the regulations on Google. And can you just fit a 17th edition DB over there. Changing the main switch from 100A?

Welcome to the forum MylesOD, I have relocated the thread to the non-UK Electrical works section.

Thank you I'm not really sure how to work it yet

Can you elaborate on the type/size of house?

If this is a 'normal' house where you expect to use appliances such as a kettle, toaster, etc, the 15A isn't going to go very far at all, as Tel says. On the other hand, if this is some remote hillside shack, and the supply is just to power a few lights and maybe a radio, then it might just about be sufficient.

Not sure why you'd need to change a 100A main switch, the 100A is the maximum current it can be used for, and does not refer to any limit at which it will trip out.

He already has a house that he lives in. This is a rural holiday home. I explained about how low 15A is in regard to the cooker and kettle. Both will be gas. It was more a question of is twin and earth acceptable to use and if the like the disconnecor to be the same rating as the main fuse. They seem to use copex and basically any colour of cable they have.

You will need to comply with the Portuguese wiring regulations, which are unlikely to permit twin and earth or a 17th edition consumer unit.
However I do not know their regulations.

That's my problem I don't lol. Thanks

Yep 15A and 20A single phase domestic supplies aren't uncommon elsewhere in the world. I've seen high density African housing fed on a maypole distribution system and each premises receives a 10A supply on a 1mmsq incoming cable.

Here's a couple of links to previous threads about Portugal. Info is a bit thin I'm afraid.
