Theoretically, UPS need not be earthed but practically the system neutral shall be referenced. Sometimes the problem surfaces in the shoulder. This is easily measured by using a standard volt meter and placing one probe on the neutral wire of a standard receptacle outlet and the other probe on the ground wire. Many people consider the seated row an exercise for the back and shoulders, but the neutral grip (where your palms face each other) is a great We can earth the Neutral in this case, but then it means you're into a multi-pole changeover switch for the by-pass (so that the earthed UPS output Neutral is never connected to the Supply Neutral), as otherwise, you would have made an additional connection between Neutral and Earth in the installation - and this is not allowed. Modular  With this transformer a new neutral is created. Also, the neutral is designed to be switched The neutral wire is associated with many misunderstandings and myths related to power quality.
