23.2.8 The permitted trip level for a Type CCID20 device intended for use on a circuit with multiple frequencies shall be determined as described in 23.2.7 except that the Frequency Factor is multiplied by 20. The trip threshold shall not exceed 70 mA.23.2.9 A CCID intended for use on a circuit with multiple frequencies shall be tested with the specific supply or at a sufficient number of frequencies to determine whether operation with any intended supply is assured.23.2.10 A CCID that is rated for operation with more than one type of supply, that is 60 Hz and higher frequencies or other combinations, shall be tested using each type of supply or a variety of supplies sufficient to cover the claimed range of supplies.23.3 Interrupting time23.3.1 A CCID shall be capable of interrupting the electric circuit to the load when the fault current to ground, I, is within the range of the trip threshold, as specified in Table 4 or Table 5, to the value related to 500 ohms (the minimum equivalent for the body) determined by using the equations shown below, within the time interval Tin accordance with the relationships in Table 6, except that the time to trip is not required to be less than 20 ms.
