We do not stock CTs larger than what we have on our website.  The Largest CT we carry is 5000A, 180mm x 130mm inside diameter, split core.

If you want to supply your own CTs please note:
Many CTs out there are 5A output, or a Voltage output instead of Amperage output.  Our meters are designed for 26.6mA output CTs only.  If you have 26.6mA output CTs they may work fine.  Other kinds of CTs could damage the meters.
