If you plug in a washing machine without turning on the breaker, it means the electrical circuit that powers the washing machine is not active. In this case, nothing will happen when you try to turn on or operate the washing machine because it is not receiving any electrical power.
When you plug an appliance like a washing machine into an electrical outlet, the circuit needs to be complete for the appliance to function. The breaker or fuse is a safety device that controls the flow of electricity to the circuit. If the breaker is turned off or the fuse is blown, the circuit is effectively disconnected, and no power will reach the washing machine.
To operate the washing machine, you will need to turn on the breaker or replace the blown fuse to restore power to the circuit. It's important to note that working with electrical circuits and breakers can be dangerous if you're not familiar with proper safety procedures. If you're unsure about how to handle electrical issues, it's best to consult a qualified electrician to ensure your safety and prevent damage to the appliance or the electrical system.
