The only thing most folks need to know is, lose the neutral connection, whether inside the rig or anywhere in the system going to the rig, and you will likely burn up a number of devices and equipment. As a lineman, I have measured in excess of 180 volts on one leg at a house panel and less than 60 volts on the other leg, still 240 across the hots, and all this due to a poorly made splice in the service cable neutral. Fortunately, none of the customer’s property was damaged in the one incident that I’m describing. Again, this really is all anyone really needs to know, and this can occur if the service is a 208 volt or a 240 volt.
