Electrical Wiring in the Home/converting220 circuit to 110

Question
Al,
Please instruct me as to how I go about converting a 220 volt circuit to 110 volts---at the circuit breaker. I have a pretty good idea about what I need to do, but would appreciate an expert opinion.

                   Thank You,

                            Michael Adams

Answer
Michael, a 220v circuit breaker will have two terminals for the user to connect to.  Voltage across these two will be 220volts.  Voltage between either of these and the neutral bus will supply 120volt.  A two wire circuit, therefore,  connected with the white to the neutral bus and a colored wired connected to one terminal of the breaker will constitute a 120volt circuit.  Normally a 220volt breaker (double pole) will be replaced with two 120volt breakers (single pole)so that when one breaker is turned off the other is not affected.

I held a California Electrical Contractor`s license from 1958 to 1970. Moved to Arkansas and contracted from 1970 to 1993 when I retired. I currently hold an Arkansas Lifetime Master Electrician`s license. During that span of time I`ve worn many hats, from estimating job costs to trouble shooting, from crawling attics to paying the bills. But I think that the part that`s most enjoyable is what I`m doing now, namely helping others with the solving of their problems and answering their questions.
