It serves as a connection point for my generator, allowing me to safely transfer power to my home. Knowing the purpose and function of this equipment is crucial for making an informed purchase.
Choosing the Right Material
I discovered that inlet boxes come in various materials, such as metal and plastic. Metal boxes tend to be more durable and weather-resistant, which is particularly important for outdoor installations. I prefer a sturdy option that can withstand the elements and potential wear over time.
