31.1 The power input to an appliance shall not be more than 105 percent of its marked rating.
31.2 To determine whether an appliance complies with the requirement in 31.1, the power input is to be measured with the appliance at normal operating temperature under full-load conditions (if required for normal operation), and while connected to a supply circuit adjusted to be the highest of the following:
a) The marked voltage rating, or
b) The highest voltage of the applicable range of voltages specified in 53.1 if the marked voltage is within one of the voltage ranges indicated in 53.1.
If an appliance employs a nonmetallic element (such as carbon), the power input is to be determined for an unused element. |
