What Is an Outdoor Panelboard?

An outdoor panelboard is an electrical distribution assembly designed for installation in an exterior environment. Like an indoor panelboard, it distributes incoming electrical power to individual branch circuits and provides overcurrent protection through circuit breakers or fuses. The primary difference is its enclosure, which must be suitable for the environmental conditions where the equipment will be installed.

Outdoor panelboards are commonly used at commercial buildings, industrial facilities, utility installations, equipment areas and other locations where electrical distribution equipment must be installed outside. Depending on the application, an outdoor panelboard may serve lighting circuits, HVAC equipment, pumps, machinery or other electrical loads.

Outdoor Electrical Panel Enclosures and Environmental Protection

Outdoor electrical panels require enclosures selected for their installation environment. Exposure to rain, moisture, dust, sunlight, corrosion and other environmental conditions can affect electrical equipment. The enclosure type must be appropriate for the location and the level of protection required.

NEMA enclosure ratings help identify the environmental protection provided by an electrical enclosure. Certain outdoor-rated enclosure types are designed to provide protection against rain, snow, windblown dust or other outdoor conditions. The correct enclosure depends on the actual installation environment. An outdoor-rated panel should not automatically be assumed suitable for every wet, corrosive or hazardous location.

Commercial and Industrial Outdoor Panelboards

Outdoor panelboards are used in a variety of commercial and industrial electrical systems. They may distribute power to exterior lighting, HVAC equipment, pumps, machinery, parking facilities and other electrical loads. They are also used where building layouts or equipment requirements make an exterior electrical distribution location practical.

When selecting or replacing an outdoor panelboard, it is important to match the equipment to the electrical system and installation requirements. Factors to consider include:

  • Voltage rating: The panelboard must be rated for the electrical system it will serve.
  • Amperage rating: The panel's current rating and main device configuration must be appropriate for the installation.
  • Phase: Confirm whether the application requires single-phase or three-phase distribution.
  • Circuit capacity: The number and type of branch circuits must meet the electrical system's requirements.
  • Enclosure rating: The enclosure must provide suitable protection for the actual outdoor environment.
  • Breaker compatibility: Circuit breakers must be listed or otherwise approved for use with the specific panelboard.
  • Manufacturer and catalog number: Identifying the original equipment helps determine the correct replacement or compatible components.

Panelboard selection and replacement should be handled by qualified electrical professionals who can verify the equipment's ratings, application and applicable electrical requirements.

New, Used, Surplus and Obsolete Outdoor Panelboards

Finding a replacement outdoor panelboard can be challenging when an existing unit is discontinued, damaged or no longer available through regular distribution channels. ESU specializes in buying and selling surplus and hard-to-find electrical equipment, helping customers locate products for existing installations and electrical projects.

We also purchase new and used electrical panelboards from contractors, businesses and facilities that have excess inventory or equipment removed during upgrades and renovations. If you have surplus outdoor panelboards or other electrical distribution equipment, contact ESU to discuss selling it.

When requesting a panelboard, provide the manufacturer, catalog number, voltage, amperage, phase, enclosure rating and available circuit information. Photographs of the equipment nameplate and interior labeling can also help with identification. These details make it easier to determine whether a particular panelboard may meet your requirements.
