To order, replace the CT-0360 part number suffix “-xxx” with one of the available Rated Amps values. The “Max. Amps” is the highest continuous current that the CT can withstand without damage. The “Max Wire Gauge” is the largest wire gauge that should fit through this size of CT. * These sizes may or may not fit, depending on the insulation thickness.
