So is it 220 or 240?
Simply put it’s 240 volts. 220 is a very old school phrase, however, the term 220 is very common still today.
But how do we get 240 volts? Well, it all starts from the transformer up on the road. A single hot leg goes into the transformer and gets split by 180 degrees and alternates 60 times each second. Each hot leg gives us 120 volts, hence 240 volts.
In this video, I show you how to install a 20 amp 240 volts without a return path, otherwise, known as a neutral. For this, we don’t need one.
