47 Leakage Current Test Following H

47 Leakage Current Test Following Humidity Conditioning47.1 A cord connected device rated 250 volts or less shall comply with the requirements for leakage current in 46.1, following exposure to air having a relative humidity of 88 ‡2 percent at a temperature of 32 ‡2°C (90 +4°F).47.2 To determine whether a unit complies with the requirement in 47.1, a sample of the unit shall be heated to a temperature just above 34°C (93°F) to reduce the risk of condensation of moisture during conditioning. The heated sample shall be placed in the humidity chamber and shall remain for 48 hours under the conditions specified in 46.1. Immediately following the conditioning, the sample shall be removed from the humidity chamber and tested unenergized as described in 46.7 (a). The sample shall then be energized and tested as described in 46.7 (b) and (c). The test shall be discontinued when the leakage current stabilizes or decreases.48 Input Test48.1 The input current to a device shall be measured with the device operating under conditions of maximum rated load as described in 48.2. The current input shall not be more than 110 percent of the rated value.48.2 Maximum rated load refers to the rated output of the device. During this test, the EV supply equipment shall be connected to a variable resistive load set to draw the maximum rated output from the device.49 Temperature Test49.1 Under the conditions specified in 49.2, the device shall not reach a temperature at any point high enough to cause a risk of fire, damage any material used, cause a protective device to operate, or exceed the temperature limits specified in Table 22. During this test, the ambient temperature shall be as specified in 49.9.
