4.2: Installing Current Transformer Sensors Terminated to Meter
The Nexus® 1500+ meter measures current using traditional 5 A secondary or 1 A
secondary current transformers. These transformers step down the primary current to
a range that they meter and sense.
The Nexus® 1500+ meter is designed to have current inputs wired in one of three
ways. Diagram 4.1 shows the most typical connection where CT Leads are terminated
to the meter at the current gills. This connection uses nickel-plated brass rods with
screws at each end. This connection allows the CT wires to be terminated using either
an "O" or a "U" lug. Tighten the screws with a #2 Phillips screwdriver.

Other current connections are shown in sections 4.2 and 4.3. Voltage and RS485/KYZ
connections can be seen in Figure 4.4.
Wiring diagrams are shown in Section 4.12 of this chapter; Communications
connections are detailed in Chapter 5.
NOTE:
For sustained loads greater than 10 A, use pass through wiring method (Sec-
tion 4.3), using 10 AWG wire.
