I need to use two identical isolation transformers or buy a product.
AC power: 2kVA
Input voltage: 220V
Output voltage: 110V
Secondary current: 18.2A
Insulation type: E
110V outlet has hot for short slot, ground for tall one.
The narrow slot is considered “hot” and is where the alternating current power comes out. The wiring behind the outlet to this slot is usually black in the U.S. The wide slot is considered the “common” and is supposed to be grounded. Using the white wire as a common grounded wire, means that everyone is working from the same zero voltage position.
The single coil wire is connected to the short slot, which means is it is the secondary coil.
