Method to Convert 220 volt to 120 volt

Voltage Converters or Transformers for Specific 120 Volt Applications: A 120 volt circuit cannot be tapped off of a 220 volt circuit simply because there is no insulated neutral wire conductor that is used in this type of 220 volt circuit.

    How can I install my own power generator at home, using solar source or wind? What kind of materials needed for that purpose, and where can I get them??

  2. Steve Wiser says:

    Would it be possible for me to safely tap into a 220v junction box (with an insulated neutral wire) for a 110 power supply?

  3. joe says:

    I would like information on how to build a converter box with a 220 volt plug and cable going in the top of the circuit breaker box and 4 20amp/120vac 4 outlet recepticles coming out the bottom. I have seen them and used one before when i was performing in a band at bar plug into a 220 recepticle on the wall, it was portable

  4. Dave Rongey says:

    Sure Joe, here is an example with the basics:
    The power source must be decided for what is available at a typical location, this will specify the size of the primary cable and the size and type of male plug or cord body that will be used.
    The primary cable would be 4-wire, 2 Hots: Black and Red, 1 Neutral White, and the Ground. The primary cable is connected as the LINE to a 2 circuit panel, the Neutral and Ground wires attaching to their own separate terminal blocks.
    One 2-pole circuit breaker is installed in the panel which would provide 2 circuits of power out to a 2-gang metal outlet box. The Cable feeding the outlets would be a 4-wire like the primary cable but sized to the circuit, possibly 15 or 20 amp for example. Of the cable to the outlet box the black wire connects to one outlet, red to the other, the neutral is shared, the ground shared and bonded to the box. Connections to the outlets as noted in wiring diagrams section.
    Hope this helps – send me a tune!
