Single-phase 6-50 is commonly used on farms for silo unloaders, and is used with a 6-gauge flexible power cord up to 200 ft (61 m) long. The 6-50 receptacle charges electric vehicles at the same 32- or 40-ampere maximum from charging stations , on a short cord, as the more versatile 14-50 with its fourth prong neutral not used currently for any ...
The induced alternating current flowing through the resistance of the cable ground conductor will cause a small AC voltage drop across the cable ground. This is added to the signal applied to the input of the next stage. In audio equipment, the 50 or 60 Hz interference may be heard as a hum in the speakers. In a video system it may cause ...
In the United Kingdom and in Ireland, this system is usually referred to simply as a "13 amp plug" or a "13 amp socket".
