I need to make a short extension cord that goes from my portable
generator 240V 4-wire receptacle to a 3-wire receptacle that powers 2
120V house circuits. The 3-wires are red and black and white. How do I
make this? The 3 wires go into a junction box where the white wire is
attached to some kind of common connection and the red and black are
each attached to its own toggle switch that flips the power between
the power company and the generator.

TIA

did you know some main service breaker boxes support a either normal
or emergency mode lock out, which safely backfeeds your home and
prevents accidently powering the power companies lines

I think that the best thing to do at this point is to provide a link
to pictures of the configuration. I will work on this today. I believe
the installation was done professionally and the solution is simple
but I just do not have the resources beyond asking for help here.
Thanks for everyones input.

Take pictures of what you have. And/or the voltage and current
ratings of the plugs

Post them to tinypic.com, then post the links here.
