But when single phase 220 volts is needed the electrician will tap 2 of the 3 phase power lines for 220 volts single phase, assuming the 3 phase is 220 volts. If the 3 phase is 440 volts or higher the electrician will have to install a step down transformer to 220 volts. Share this post Link to post Share on other sites
