UL197铭牌

现做一款北美商用电磁炉，三相208V，按UL197要求铭牌标208Y，想问各位大神是否不用标“V”了，如果有铭牌例子能否分享下，谢谢

补充UL197条款如下：

83.1 An appliance shall be rated in volts, amperes or watts, and frequency. The rating shall include the
number of phases when the appliance is designed for use on a polyphase circuit, and an appliance
intended for a 3-phase 4 wire "Y" connection shall include "Y" in the voltage rating (such as 208Y, 480Y).
