Figure 4-8. CT phase association for 3-phase, 3-wire delta loads.
For example, Current transformer installed in phase with A reference voltage must be
installed on CT1, CT3, CT5, etc. Current transformers installed in phase with C reference
voltage must be installed on CT2, CT4, CT6, etc.
2. Each A-C combination is a single meter point (see Table 1 for full listing):
-
Meter #1 (M#1) is measuring CT1 and CT2
-
Meter #2 (M#2) is measuring CT3 and CT4
-
repeat for M#3 to M#12
3. After completing all current transformer terminations, connect four (4) current
connectors and then remove the twenty-four (24) shorting links.
4. Follow local codes for installation requirement, e.g. conduit, fused disconnect,
distance, and wiring.
5. Installation of 0.1A inputs and CL10 (or 5A inputs) are the same.
CAUTION:
If breakers are energized, shorting links must be installed before:
a) Disconnecting the CT headers or
b) Replacing or installing meter heads on the panel.
WARNING:
Bodily injury or damage may result if shorting links are not installed.
