-
- If you have two 110V outlets, one on one phase, the other on a phase
- 180 degrees away, then you could access 220V. wire one 3 prong male
- plug connecting to the HOT pin, and connect that to one of the hot
- pins of the European female 220V outlet. Do not connect the neutral
- wire pin of the male to anything! Wire the second 3 prong male
- connecting to the HOT pin, and connect that to the OTHER power pin on
- the European 220V outlet. Connect the European safety ground (if there
- is one) to the safety ground of one or both safety grounds of the
- 3 prong male 110V plugs. Check your work for safety, then plug in
- the plugs into the selected outlets, then measure the European female
- to see if you are getting 220V.
-
- Be sure to use wire heavy enough to carry all the current the outlets
- are capable of feeding (determined by what size breakers are in use)
- Breakers, for more safety, should be mechanically linked, so an
- overload on one outlet circuit will shut both off.
- and wire suitable for the physical abuse the envirnment can give.
- Use 2/14 stranded cord for example.
