How do I connect three phase power with change overswitch to db three phase show the diagram?
That makes sense. What kind of safety precautions should I take when working with three phase power?
It's important to wear appropriate personal protective equipment, such as gloves and safety glasses. You should also make sure to de-energize the circuit before working on it and use a voltage tester to verify that there's no power going to the circuit. Additionally, it's always best to work with someone else when dealing with high voltage circuits.
