The way you read is from line to netural that is correct.

120208 delta. 8 Delta Secondary Voltage:. However, many jurisdictions forbid more than one class for a premises' service, and the choice may come down to 1/240 split-phase, 8 single-phase or three-phase (delta), 1/8 three-phase (wye), or 277/480 three-phase (wye) (or 347/600 three-phase (wye) in Canada). This is why 480 to 1/8 transformers are almost always delta on the 480 side.

If there were 3 transformers on a pole connected wye on the primary, and delta on the secondary, and you opened one of the cut-outs, you'd still have 3 phase power available on the secondary. Also why most larger motors are delta connected. This is the most common four-wire three-phase delta service and is essentially a 240 volt, three-phase, three-wire delta service with one of the 240 volt transformer winding center tapped to provide two 1 Vac circuits, which are 180 degrees out of phase with each other.

The conductors connected to the three points of a three-phase source or load are called lines. This transformer is designed to convert 3-phase 8v to 3-phase 480 Y 277 to run equipment such as panels, motors, CNC machines, welders, conveyor systems, pumps, printing equipment, fabrication tools, and other business machines. The normal three phase A/C unit is wired for either 8 or 240 volts as I mention above you will read 240 volts between hot lines and I know you read 1-1-8 that is normal to read that and that is on Delta system.

480 Delta Secondary Voltage:. This transformer is designed to convert 3-phase 480v to 3-phase 8v/1 to run equipment such as panels, motors, CNC machines, welders, conveyor systems, pumps, printing equipment, fabrication tools, and other business machines. However, if dual voltages are needed (e.g.

1/8-Volt 3-Phase WYE or Delta Surge Panel in Gray Leviton's Surge Protection Devices can be used individually Leviton's Surge Protection Devices can be used individually or as part of a coordinated application strategy, to protect sensitive electronic equipment, in industrial, commercial and residential locations, from the stress and degradation inflicted by voltage transients. The three components comprising a three-phase source or load are called phases. 1/8) or preferred for lower line currents, Y-connected systems are the configuration of choice.
