Differences Between SDP and MDP Panels in Electrical Distribution Systems
The Switchgear Distribution Panel (SDP) and Main Distribution Panel (MDP) are two essential components in an electrical distribution system, though they are often mistakenly perceived as similar devices.
For professionals in the electrical field and building owners alike, understanding the differences between these panels is crucial for ensuring both the efficiency and safety of the electrical system.
A comprehensive understanding of the differences between SDP and MDP panels can improve the overall performance of the electrical distribution system. Here, we’ll explore the roles, functions, and main characteristics of these two types of panels.
Differences in Function and Role in Power Distribution
The Main Distribution Panel (MDP) acts as the primary distribution hub in the electrical system. It receives power from the main source, such as a transformer or power generator, and distributes it to various branch panels like the SDP, as well as to large loads within a facility. In other words, the MDP serves as the starting point for power distribution within a building or industrial facility.
On the other hand, the Sub Distribution Panel (SDP) distributes power from the MDP to more specific electrical loads. The SDP is usually located closer to the electrical loads, for instance, on a specific floor in a building, and distributes power to particular equipment groups or areas.

Power Distribution Levels
Another important distinction between MDP and SDP is the level of power distribution they manage. The MDP operates at the primary distribution level, handling power from the main source and distributing it throughout the system.
The SDP, in contrast, functions at the secondary distribution level, further distributing power from the MDP to more specific loads, such as certain areas or equipment that require less power.
Power Capacity Management
In terms of power capacity, the MDP handles a larger amount of electricity, sufficient to supply an entire building or facility. This panel is responsible for distributing energy from the main source to the entire electrical network within the facility.
The SDP, on the other hand, handles a smaller and more focused power capacity, typically limited to specific areas or electrical loads. For instance, an SDP might distribute power to a single floor of a building or to certain specific equipment.

Protective Devices
Both MDP and SDP panels are equipped with protective devices like MCBs (Miniature Circuit Breakers) or MCCBs (Molded Case Circuit Breakers), which protect the circuits from electrical disturbances such as overcurrent. However, the protective devices in an MDP usually have a higher capacity, as the MDP handles higher levels of electrical power.
In summary, the differences between SDP and MDP panels lie in their function, distribution level, and power capacity management. The MDP serves as the primary distribution center, while the SDP distributes power to specific parts of a building. Both require proper handling to maintain a safe and efficient electrical system.
For building owners and electrical professionals, understanding these differences is essential to ensuring that the electrical distribution system operates optimally.
