Ive been reading blogs regarding exisitng 240v 3 wire circuits being converted into 4 wire 120/240v circuits. We all know that using a bare ground conductor as a combination neutral conductor is a bad idea and will not comply with code. I am curious why there isnt much mention regarding using a buck/boost transformer and creating a neutral conductor in particular situations. For Example: in a residential setting where there is currently an oven installed and connected with 8/2 romex. The oven is upgraded and required to have a 120/240v 34.8 amp single phase circuit. Obviously there is not an insulated neutral conductor present and installing a new 8/3 romex with ground is prohibitive. Installing a 10 kva buck/boost transformers, 240v primary / 120/240v secondary are very expensive but could save money and a headache vs. installing a new circuit from the main service. These transformers will create a neutral.
Theoretically, can anyone identify an issue with this application? (other than cost), or should this theory work? I have not attempted this installation yet, but found this to be a good alternitive if it will work.
