Key Differences
4. Size, Scale, and What They Do
Let's break down the core differences between distribution panels and switchboards so you can easily tell them apart. The biggest giveaway is usually size. Switchboards are significantly larger, often taking up an entire wall or even a room, while distribution panels are typically compact enough to fit in a wall or a small enclosure.
Another crucial difference lies in their voltage and current ratings. Switchboards are designed to handle much higher voltage and current levels than distribution panels. This is because they are dealing with the incoming power from the utility company, which is often at a higher voltage than what's used in individual circuits within a building.
Their functionality also differs. Distribution panels primarily focus on distributing power to branch circuits and providing overcurrent protection. Switchboards, on the other hand, offer a broader range of functions, including switching, metering, protection, and power quality monitoring. They are the command centers of the electrical system.
Finally, think about where you'd find them. Distribution panels are common in homes, apartments, and small businesses. Switchboards are the domain of large commercial buildings, industrial facilities, and power plants. So, if you see a massive electrical panel with lots of switches, meters, and controls, chances are you're looking at a switchboard.
