Hi Carlos,

That won't work. Neutral and ground are connected together in several place=
s, including your breaker box and your neighbor's breaker box and any sub p=
anels. If you really need 220V phase to neutral and don't have an industria=
l three-phase connection to utility power, you will need to use a transform=
er.

I'm curious what would need 220V phase to neutral, but wouldn't work with 2=
40V phase to phase.

You can get 240V by finding two 120V outlets that are on different phases a=
nd hacking up a couple of extension cords. It won't work if either outlet i=
s protected by a GFCI. And of course, it's dangerous and should never be do=
ne. And it's still 240V phase to phase.

Friendly regards, Bob

Hi!

I have a device that gets its main power from a 220VAC phase to neutral
outlet and I need to connect it to a 220VAC  phase to phase outlet (110VAC
phase to neutral).

Can I do it that way, just going 220 phase to phase and grounding the
outlet neutral?

Thanks in advance!

Regards,

Carlos.
