Using 5A CT converters with the PowerHawk 6320 meter
When both low-current (200A and 400A) and high-current (600A or higher) circuits need to be
measured with the same PowerHawk meter, converters are available to allow the use of
Measurement Canada approved 5A CTs with the appropriate current rating. 5A CT converters
transform the 5A maximum output from a standard CT to the 80mA maximum of the
PowerHawk meter.
The 5A side of the converter is the black and red wire pair, and the 80mA side of the converter
is the black and white wire pair.
It is recommended that 5A converters and shorting devices be installed in a sealable metal
enclosure.
To connect the 5A CT to the converter on the PowerHawk 6320, follow these steps:
1. Connect the X1 lead of the 5A CT to the shorting device.
2. Connect the X2 lead of the 5A CT to the shorting device.
3. Connect the X1 lead (red) from the 5A side of the converter to the CT X1 lead on the
shorting device.
4. Connect the X2 lead (black) from the 5A side of the converter to the CT X2 lead on the
shorting device.
5. Connect the X1 lead (white) from the 80mA side of the converter to the X1 lead within the
25 pair cable for the selected meter point listed in Table 3.
6. Connect the X2 lead (black) from the 80mA side of the converter to the X2 lead within the
25 pair cable for the selected meter point listed in Table 3.
Figure 7 shows a 5A CT connected to the converter.
