ELITEpro XC Voltage Phase Wire Colors
NOTE: U.S. color conventions are used in the document’s diagrams. ELITEpro XC meters supplied for
international markets are provided with 5 colors of voltage leads: red, black, blue, white, and yellow.
The voltage lead sockets on the meter are all black in color and labeled L1, L2, L3, and N.
CURRENT TRANSFORMER (CT) SELECTION
NOTE: The UL listing covers the use of the following DENT Instruments CTs that are UL Recognized and
have been evaluated to IEC 61010-1:
CT‐HSC‐020‐X (20A Mini), CT‐HSC‐050‐X (50A Mini), CT‐HMC‐0100‐X (100A Midi), and the CT‐HMC‐0200‐
X (200A Midi). Though all other CTs provided by DENT Instruments have been tested and certified to the
same IEC 61010-1 standard by other Nationally Recognized Testing Laboratories (NRTLs), the use of any
other CT will invalidate the UL Listing of the ELITEpro XC. This is simply a decision made by UL, and in the
opinion of DENT Instruments, all CTs provided are equally safe to use.
Proper CT selection is critical for accurate results. Use CTs with the smallest diameter to fit around the
wire(s), and whose rated amperage is not less than 100% of the largest load expected.
Generally, best CT accuracy will result when the load operates as close to the full rating of the CT as
possible. Do not use CTs whose maximum current rating greatly exceeds the maximum current of the
load of the item being monitored.
The following table contains a list of some of the DENT Instruments CTs.
