# May I get 220v phase-neutral if all the homes in my state seems to give only 127v phase-neutral voltage on sockets? [closed]

In my state (São Paulo, Brazil), theres delta-star transformers that outputs 4-wires. Three phase and one neutral.

I've heard that one of these wires of the triphasic (R,S,T wires) and the neutral wire, outputs 220v, for easy maintening purposes (phase balancing) by the dealership.

Is it true or fake?

• In the interest of forestalling you from trying something dangerous, you should look into a transformer that will take a 220V split phase input and provide a 220V single phase output. They're not terribly expensive, especially if your power requirements are sub-kW.

• You cannot achieve 220V between phas-neutral directy. || Transistor's answer correctly tells you what CAN be achieved technically. Jun 11 at 2:05

Note, the question has been substantially edited making this portion of my answer seem irrelevant.

No. Never split loads across two sockets. If a plug comes out the pins may be live and present an electric shock hazard.

You may already have 220 V available but you have no location code in your user profile or in your question so further help is not possible.

With 127 V phase-neutral you can get $$\127\sqrt 3 \ \text V = 220 V\$$ between phases. If this is to be plug connected then a single 3-phase connector must be used to prevent the possibility of one plug being disconnected and having the pins live. Please don't mess or take chances with this.
