How thick is the power cord for a 3000W electric water heater?
According to the "current = power divided by voltage" estimate, increase the safety factor slightly above the line
No 1.78, 2.7, 4.5 square wiresMost families use 1, 1.5, 2.5, 4, four wiresPower 1KW about 5A.3KW, about 15A.2.5 square copper wire can be usedPlug or air amplification (25A).
The 3000W appliance operates at 220V voltage, and the current is about 13.6A (current = power divided by voltage). The working current of a copper core line is typically one square 4-6A. In other words, you use 3-4 square lines of power more secure.
