Glossary of System Terms

• Grounded Neutral System: A system where the neutral point is connected to earth.
• Edison System: A common name for the 120/240V single-phase, three-wire system with a center-tapped neutral, widely used for residential service in North America.
• Split-Phase: Another term for the Edison system, describing how the 240V supply is split into two 120V lines relative to the neutral.
