Where should a sub-panel be installed in a warehouse with a paint spray area that has a lot of over spray?

• A. In a concrete wall
• B. Outside, near the center of the load to be supplied
• C. Adjacent to the main panel
• D. In a separate room away from the spray area

Answer: (B)

The installation of a sub-panel in a warehouse, particularly near a paint spray area with significant overspray, requires careful consideration of safety and practicality. The correct placement near the center of the load to be supplied is important because it minimizes voltage drop and improves efficiency. Installing the sub-panel close to the load means that the electrical supply can be more efficiently distributed to the machinery or equipment it serves, ensuring that all devices receive adequate power.

Additionally, placing the sub-panel outside the spray area reduces the risk of damage from overspray. Equipment and electrical components are vulnerable to the corrosive effects of paint and solvents, potentially leading to equipment failure or electrical hazards. The selected location not only enhances the performance of the electrical system but also addresses safety concerns by protecting the sub-panel from contamination and reducing fire risk associated with flammable materials used in painting.

Therefore, installing the sub-panel outside, near the center of the load, balances both electrical efficiency and safety in the context of the warehousing environment outlined in the question.
