Types of electrical services

This electrical service is used for typical residential homes. In this service, the neutral is grounded. The voltage level between lines 1 and 2 is at 240V. This high voltage is used for heavier loads like AC .There is a 120Vsupply from line 1or 2 to neutral. This voltage is used for smaller loads like lights.
Three Phase Four Wire 208Y120V Wye
Electrical services Riverside uses this for mostly commercial purposes. The Wye in the name is read as ‘Y’ to denote the presence of a neutral. The 208V- 3 phase powers larger loads. The lower 120V powers small loads.
Three Phase Four Wire 480Y277V Wye
This is used by Electrical Service Riverside for large commercial and industrial purposes. The 480 V is used to power high load motors. Lights and small circuits use the 277V supply. If this is the primary service to a facility, a transformer will be present to step down the voltage to 120V for small loads.
Three Phase Three Wire Delta
This particular service has no neutral. The inside of a commercial motor load runs on delta services.
Delta Three Phase 4 Wire with a High Leg
This is an uncommon electrical service. Mostly found in old systems with small 3 phase loads.
These are the five types of electrical services provided based on the sector requirement. The electrical service can be a primary service provided to a location. However, a service can also be created inside a commercial sector with a transformer.
