my boss and i have been having a disagreement, about the common wire in a three wire split phase 240 a.c. circuit. the argument is , first , that the neutral wire and common wire is one in the same.. second, that this wire is only used for return voltage and is never a live wire... he says that is he taks a voltage reading from the wires connecting to the capacitor wich are ( fan , commmon , compressor) he says if he takes a voltage reading from one of the legs and the common wire he gets 240 volts, therfore he believes the common is a hot wire..
can you please explain this to me .. and also explain that the common and neutral wire is the same thing... thanks.......
