Wiring Diagrams

Overview
One of the most requested items of information that we receive is for wiring diagrams for the meters we sell.  This page contains circuit type and wiring diagrams for all the form #'s of meters, sockets and pans; with and without CTīs and PTīs, for Wye, Delta, and Network circuits.  All diagrams are presented in JPEG (.jpg) format.  Click on the type or form you need and download the jpg to your computer or printer.  After viewing or printing the wiring diagram, use the back button of your browser to return to this page.  If you have any questions concerning the diagram, please donīt hesitate to call us for clarification.

Circuit Types
1. Singlephase circuits - a singlephase circuit may be two wire (120 volts, 208 or 240 volts, or 480 volts line to line); three wire (120  volts line to neutral and 208/240 volts line to line or 208/240 line to neutral and 480 volts line to line).

Note: Parantheses indicate other possible voltages that might be available.  Three wire circuit voltages may be 120/240 volt line-groundline-line or 240/480 volt line-groundline-line.  Meters are rated 240 or  480 volt respectively.

2. Polyphase circuits - a polyphase 3 phase circuit may be: 3-wire network, 3-wire, 4-wire delta, or 4-wire wye.

3WNetwiringvolts3P3Wwiringvolts 

(120/208V or 277/480V) or meter rated 120 or 240V using line-to-ground voltage.  A 240 volt meter is used for 277/480V service.

(One phase may or may not be grounded.)  Meter rated 120, 240 or 480 volt.

(120/240V or 240/480V) Meter rated 240 or 480 volt using line-to-line voltage.

(120/208V or 277/480V) Meter rated 120 or 277 volt using line-to-ground voltage.  If 240/416 service (uncommon), meter rated 240 volt, 240 and 277 volt wye meters are applicable to either 240/416 or  277/480 volt wye service, 240 volt meters have 240V nameplates and are calibrated at 240V.  277 volt meters have 277V nameplates and are calibrated at 277V.
