The AC363RG has a number of features that make it a popular choice for industrial applications, including:

• A switch-operated disconnect that allows for safe isolation of the load from the busway system.
• A fusible element that protects the load from overcurrent conditions.
• A ground stab that ensures proper grounding of the load.
• A durable construction that can withstand harsh industrial environments.

The AC363RG is typically used in industrial applications such as:

• Manufacturing facilities
• Power plants
• Data centers
• Commercial buildings

It is important to note that the AC363RG is a high-voltage device and should only be installed and serviced by qualified electricians.
