4 FAQs about Switchboards vs panelboards

What is the difference between a switchboard and a panelboard?

Switchboards and panelboards indeed serve similar functions in power distribution systems, but they differ in several key aspects: Panelboards are typically flush-mounted or surface-mounted, meaning they are installed within walls or on surfaces. Switchboards are freestanding units. They are not installed within walls but are standalone structures.

What is the difference between switchgear and panelboard?

Switchgear controls, isolates, and protects high‑current circuits; switchboards distribute power with higher capacity; panelboards split power to branch circuits with lower load. When it comes to electrical distribution systems, terms like switchgear, switchboard, and panelboard often get tossed around—and sometimes confused.

Can a switchboard be installed in a cabinet?

These assemblies are generally accessible from the rear and front and are not intended to be installed in cabinets” [NEC 100]. Switchboards are similar to panelboards in that they are normally rated for up to 600V, they can handle higher fault currents than panelboards and load centers.

Do I need a switchboard?

Load Requirements: If the total current exceeds 1200A, a switchboard is necessary. Space Constraints: Panelboards are more compact and suitable for tight installations. System Complexity: Switchboards support complex power distribution and integrated controls. Budget: Panelboards are generally less expensive and simpler to install.
