What is a 240 volt 3 phase 3 wire grounded b phase system ...
A 240 volt 3 phase 3 wire grounded B phase system is also called a quadraplex configuration. You actually have four conductors, not counting the protective earth ground, which makes five wires.2700DB0202R03 12 Data Bulletin 09 2012 Replaces ...
UL labeled as suitable for use on grounded B phase systems, when applicable. Devices NOTE: All equipment listed in this document is rated for use on systems with a grounded B phase. BP Fusible Switches BP switches can be used on corner grounded delta systems in manually or electrically operated, upright or inverted mount, and 2 or 3 pole versions.Corner Grounded Delta Circuits – Continental Control ...
Corner Grounded Delta Circuits Occasionally, (especially in older facilities or in oil well and irrigation applications), you may encounter a three phase delta service with one phase (leg) connected to ground, called a “corner grounded delta” or “grounded leg service”.Corner Grounded Delta (Grounded B Phase) Systems ...

Installations and inspections of corner grounded systems can be a bit intimidating both to seasoned veterans and to students of the Code. All the rules for grounded conductors must be applied identically to the grounded conductors of all systems, whether the grounded conductor is a grounded neutral conductor or a grounded phase conductor. The ...Three phase electric power
There are two basic three phase configurations: wye (Y) and delta (Δ). As shown in the diagram, a delta configuration requires only three wires for transmission but a wye (star) configuration may have a fourth wire. The fourth wire, if present, is provided as a neutral and is normally grounded.
