Single Phase or Three Phase?

by | Nov 1, 2017 | Additions, Renovations | 0 comments

Single phase power. Household use, safer, less efficient.

Three phase power. Commercial/Industrial use, 73% more efficient, more expensive to install, motors last longer, speed control is better.

The horizonal line in the center is zero/off/no power. As you can see, in single phase, power output drops to zero then to full then back again. Three phase power never falls to zero. It only falls to 73% of full.

Three phase power is not allowed for household use. The highly efficient overlapping power band is dangerous. If someone grips a cable energized by three phase it is very difficult to let go. Short circuits are more dangerous.
