Installation

3.1Connecting the Current Circuit

Install the wiring for the current at 600V AC insulation as a minimum. The cable connector should be rated for 6 Amps or greater and have a cross-sectional area of 16 AWG minimum.

Mount the current transformers (CTs) as close as possible to the meter for best accuracy. The following table illustrates the maximum recommended distances for various CT sizes, assuming the connection is via 16 AWG cable.

Table 3–1:CT Size and Maximum Distance

 

 

CT Size

Maximum Distance (CT to Meter)

 

 

2.5 VA

10 Feet

 

 

5.0 VA

15 Feet

 

 

7.5 VA

30 Feet

 

 

10.0 VA

40 Feet

 

 

15.0 VA

60 Feet

 

 

30.0 VA

120 Feet

 

 

DO NOT leave secondary of the CT open when primary current is flowing. This causes high voltage that will overheat the secondary of the CT. Use a shorting block on the secondary of the CT.
