It is generally not recommended to plug a refrigerator and a separate deep freezer into the same outlet, as both appliances can draw a significant amount of power, especially when they start up or run concurrently.
Refrigerators and freezers have high initial power requirements during startup, known as "inrush current," which can overload the circuit if both appliances are connected to the same outlet. This can cause the circuit breaker to trip or create electrical issues.
To ensure safe and efficient operation, it is best to plug each appliance into a dedicated circuit or separate outlets on different circuits. This helps distribute the electrical load evenly and reduces the risk of overloading the circuit. If you're uncertain about the electrical capacity of your garage or the specific outlets, it's advisable to consult a qualified electrician who can assess your electrical system and make appropriate recommendations.
