Electrical Panels In Stock & Built Fast

Electrical Panels — Emergency Build & Same-Day Stock

When a facility loses power, a manufacturer quotes a 20+ week lead time, or a project deadline slips because the gear hasn't shipped, the panel itself is rarely the hard problem. The hard problem is getting one built, tested, and on a truck this week. We stock and build electrical panels across the full commercial and industrial range, from 600A panelboards through 4000A switchboards, with 24-48 hour turnaround when manufacturer lead times are 20+ weeks.

Verified Breakers is a B2B distributor and engineered build shop for electrical contractors, facilities managers, data center operators, and industrial buyers across the United States. Every panel ships from US stock or a domestic build cell, not a backordered factory line. If a brand, amp rating, or voltage configuration isn't on this hub page, it's almost certainly available through a rush build — request a quote and we'll confirm stock or build time inside one business day.

Panelboard vs Switchboard vs Load Center — What You're Actually Buying

Buyers searching for "electrical panels" land here looking for one of three distinct product families. Specifying the wrong one slows the quote, the submittal, and the install. Here's the distinction we use on every job.

Panelboards

Panelboards are the workhorse distribution panel for commercial and light-industrial branch circuits. Typical ratings sit in the 100A through 1200A range at 208Y/120V, 480Y/277V, or 480V three-phase. Configurations split into main lug only (MLO) panelboards fed by an upstream device, and main breaker panelboards that serve as their own disconnect. Square D NF and NQ, Siemens P1 and P5, Eaton Pow-R-Line, and GE A-Series are the families we move most often. UL 67 listed, indoor or NEMA-rated outdoor enclosures, 65kAIC or higher interrupting ratings where the fault duty calls for it.

Switchboards

Switchboards step up where panelboards stop. Free-standing, front-accessible (or front-and-rear on larger frames), and built to UL 891. We stock and build switchboards from 800A through 4000A, with 1600A, 2000A, 2500A, and 3000A frames covering most service entrance and main distribution applications. Square D QED-2 and QED-6, Siemens SB1 and SB3, Eaton Pow-R-Line C and Magnum, GE Spectra, and ABB ReliaGear are the standard families. Sections include main devices, distribution sections, metering compartments, and sub-feeds for downstream panelboards.

Load Centers

Load centers share DNA with panelboards but sit at the smaller end of the spectrum — typically up to 400A — and are common in light commercial, multi-tenant, and tenant-improvement work. Siemens load centers and Square D Homeline and QO load centers cover most of what contractors request. They're listed here so multi-trade projects can source the full panel stack from one supplier rather than chasing three.

Amp Ranges We Stock and Build

Our build margin sits in the mid-to-large commercial and industrial range, where factory lead times stretch longest and emergency demand concentrates. Smaller frames are routinely stocked; larger frames are routinely built.

• Panelboards: 100A, 200A, 400A, 600A, 800A, 1000A, 1200A
• Switchboards: 800A, 1200A, 1600A, 2000A, 2500A, 3000A, 4000A
• Load centers: 100A through 400A in single-phase and three-phase configurations
• Voltage classes: 120/240V single-phase, 208Y/120V three-phase, 480Y/277V three-phase, 480V three-phase delta

Common configurations we ship same-week include 600A and 800A Square D panelboards, 2000A and 2500A Eaton switchboards with metering sections, and SoCal Edison-spec metered switchboards for California utility-coordinated jobs.

Brands We Stock

We carry the five manufacturer families that cover roughly every panel specified in US commercial and industrial construction. Each brand has its own collection hub with deeper detail, in-stock lists, and rush build notes.

Square D (Schneider Electric)

Square D is our highest-volume brand and the most commonly specified panel and switchboard line in North America. NF and NQ panelboards, QED-2 and QED-6 switchboards, and the I-Line distribution family cover most commercial and industrial installations. See the Square D panelboards and Square D switchboards collections for full breakdowns.

Siemens

Siemens P1 and P5 panelboards and SB1, SB2, and SB3 switchboards are second-volume for us, with strong demand in data center, hospital, and large multi-tenant projects. Siemens load centers cover the light-commercial end. See the Siemens panelboards, Siemens load centers, and Siemens switchboards hubs.

Eaton

Eaton Pow-R-Line panelboards (1a, 2a, 3a, 4) and Pow-R-Line C and Magnum switchboards. Strong on industrial and process plant work, particularly where Cutler-Hammer legacy gear needs matched replacements. See Eaton panelboards and Eaton switchboards.

GE

GE A-Series and AV-Line panelboards, Spectra switchboards, and the legacy Powerbreak and Powermark families. Commonly requested as direct or like-for-like replacements in older facilities. See GE electrical panels.

ABB

ABB ReliaGear panelboards and switchboards, with industrial and utility-adjacent demand. Frequently specified on engineered process projects and where ABB drives and switchgear are already in place. See ABB electrical panels and ABB switchboards.

Applications We Build For

Every panel we ship goes to one of four buyer types, and the spec sheet usually maps cleanly to one of them.

Commercial Construction

Office buildings, retail, hospitality, healthcare, and multi-tenant fit-outs. Typical specs: 400A through 1200A panelboards at 208Y/120V or 480Y/277V, mix of main breaker and main lug, AIC rating matched to the upstream service. Submittal packages and approved drawings supplied with every order.

Industrial and Process

Manufacturing plants, food processing, oil and gas, water treatment. Switchboards in the 1600A through 4000A range, often with metering sections, ground-fault protection, and integrated transient voltage surge suppression. UL 891 listed, 65kAIC or 100kAIC interrupting rating depending on the available fault current.

Data Centers and Mission-Critical

Colocation, hyperscale, and enterprise data centers running tight power-density specs. We supply panelboards and switchboards into the critical and non-critical busses, often coordinated with UPS systems, automatic transfer switches, and parallel redundant topologies. Same-week ship matters here more than anywhere — an empty rack waiting on a 16-week factory order is unbillable space.

Multi-Tenant and Service Entrance

Apartments, mixed-use, and small-commercial service entrance applications. Metered switchboards (including SoCal Edison-spec utility coordinated builds), CT cabinets, and stacked load center configurations. We ship to general contractors, electrical contractors, and utility-coordinated developers.

Why Buy Through Verified Breakers

Factory lead times on commercial and industrial panels have run 14 to 26 weeks for most of 2025 and 2026. That gap is the entire reason this business exists.

• Rush build cell: Most 600A through 1200A panelboards and 1600A through 3000A switchboards can ship inside 24-48 hours from quote-to-truck on emergency orders, against 20+ week manufacturer factory lead times.
• Multi-location US stock: Inventory across Colorado, Texas, and California, with nationwide shipping. No import wait, no customs.
• Brand depth: Square D, Siemens, Eaton, GE, and ABB across every amp range. If a project spec calls for a like-for-like replacement, we either have it or build it.
• Engineered submittals: Drawings, cut sheets, and submittal packages supplied with every quote so the EC and engineer can sign off without delay.
• BBB Accredited: US-registered, US-staffed, no offshore sales floor.

Request a Quote

Send the spec sheet, single-line, or just the bill of materials. We'll come back inside one business day with confirmed stock, confirmed build time, and a fixed price. For emergency builds, call the 24/7 line and we'll quote inside the hour.

The panel itself is the easy part. Getting it on a truck this week is what we do.
