Installation

 

 

Installing the Sense Voltage and Control Voltage Cables in Wye and Delta Services

The sense voltage (A, B, C, N) provides phase voltages for metering. The configuration depends on the type of service being metered:

see “For a single-phase panel with the 120V variant of the meter:” on page 15

see “For a 208Y/120V three-phase wye panel with the 120V variant of the meter:” on page 16

see “For a 416Y/240V (or 380Y/220V) three-phase wye panel with the 230/240V variant of the meter:” on page 17

see “For a 480Y/277V three-phase wye panel with the 120V variant of the meter:” on page 18

see “For a 600Y/347V or higher three-phase wye panel with potential transformers with the 120V variant of the meter:” on page 19

see “For a three-phase Delta panel with the 120V variant of the meter:” on page 20

The PowerLogic EM4833, EM4880 and EM4805 meters are shipped from the factory with a control voltage jumper that can be used to to connect the control voltage input and the sense voltage inputs to provide control voltage to the unit. The following procedures explain how to connect the sense voltage inputs for each of the service types.

For a single-phase panel, use a 3-wire (red, black, white), 14 AWG

(1.63 mm2), 90°C (194°F) cable. For a three-phase panel, use a 4-wire (red, black, blue, white), 14 AWG (1.63 mm2), 90°C (194°F) cable. For a Delta service, use a 3-wire (red, black, blue), 14 AWG (1.63 mm2), 90°C (194°F) cable. Metallic, flexible armored cable (BX cable) is recommended for commercial installations as shown in Figure 6 on page 15.

The PowerLogic meters must be connected to the sense voltage and control voltage through a properly rated disconnect that disconnects all line and neutral wires, so it can be powered down. The disconnect must be located within easy reach of the meter operator, and must be labeled as such. Opening the disconnect or breaker is the disconnect device. For multiple PowerLogic meter installations, the same disconnect can be used to power all meters, and must be labeled for all meters it supplies power to. The disconnect device must meet IEC 60947-1, IEC 60947-3 and/or comply with the local electrical code.
