{"title":"Switchboards","description":"\u003ch1\u003eSwitchboards — Emergency Build \u0026amp; Same-Day Stock\u003c\/h1\u003e\n\n\u003cp\u003eWhen a switchboard build holds up commissioning, downs a plant, or stalls a tenant fit-out, the calendar matters more than the catalog. We stock and build commercial and industrial switchboards from 1000A through 4000A and above, in front-access and rear-access configurations, with fixed-mount or drawout breakers. Most orders ship inside 24 to 48 hours. We carry every major manufacturer line, including Square D, Siemens, Eaton, GE, and ABB, and we build to spec when a one-to-one replacement isn't on the shelf.\u003c\/p\u003e\n\n\u003cp\u003eThis page is the hub for our full switchboard range. If you already know the manufacturer, jump straight to the brand pages linked below. If you're still scoping the order, the sections that follow cover the switchboard types we stock, the amp ratings we build to, and the applications we ship into most often.\u003c\/p\u003e\n\n\u003ch2\u003eWhat is a switchboard?\u003c\/h2\u003e\n\n\u003cp\u003eA switchboard is the service-entrance or main distribution equipment for a commercial or industrial building. It takes utility or generator power at 600 volts or below and distributes it across feeder circuits to downstream panelboards, motor control centers, and large loads. Switchboards differ from panelboards in scale: panelboards typically handle branch circuits up to 1200A, while switchboards start where panelboards leave off and run up past 4000A. They're built around a heavy-duty bus, individually or group-mounted overcurrent devices, and a freestanding enclosure rather than a wall-mount cabinet.\u003c\/p\u003e\n\n\u003cp\u003eSwitchboards split into two broad roles. Service-entrance switchboards sit at the point of utility connection and include the main disconnect, metering provisions, and ground-fault protection where the code requires it. Distribution switchboards sit downstream and feed sub-panels, MCCs, and large equipment loads. Both can be specified with the same construction, but service-entrance units carry the metering and utility-approved features the local power authority will sign off on.\u003c\/p\u003e\n\n\u003ch2\u003eSwitchboard types we stock\u003c\/h2\u003e\n\n\u003ch3\u003eService-entrance switchboards\u003c\/h3\u003e\n\n\u003cp\u003eService-entrance switchboards include utility metering provisions, a main disconnect (fused switch or circuit breaker), and ground-fault protection on 1000A or larger 480Y\/277V services. We stock service-entrance configurations across all five major manufacturer lines. Utility approval lists vary by region, so confirm whether your local power authority requires Square D QED, Siemens Sentron, Eaton Pow-R-Line, GE Spectra, or another listed series before we cut steel.\u003c\/p\u003e\n\n\u003ch3\u003eDistribution switchboards\u003c\/h3\u003e\n\n\u003cp\u003eDistribution switchboards take feeder power from the service-entrance gear and break it out to downstream panelboards, motor control centers, and large discrete loads. These are simpler to build than service-entrance units because they don't need utility metering or main disconnect listings. We stock distribution switchboards in both group-mounted (multiple breakers behind a common door) and individually-mounted (each breaker in its own compartment) configurations.\u003c\/p\u003e\n\n\u003ch3\u003eLow-voltage switchboards (LV-SWB)\u003c\/h3\u003e\n\n\u003cp\u003eLow-voltage switchboards cover everything at 600V and below, which is the majority of commercial and industrial switchboard demand in the U.S. They're rated for 1000A to 4000A and above on the main bus, and they accept molded-case, insulated-case, or low-voltage power circuit breakers depending on the manufacturer line and the application. LV-SWBs are the workhorse class for office towers, hospitals, schools, hotels, multi-tenant commercial, and light-to-medium industrial sites.\u003c\/p\u003e\n\n\u003ch3\u003eSwitchgear-style switchboards\u003c\/h3\u003e\n\n\u003cp\u003eThe line between switchboards and switchgear blurs at the top of the LV-SWB range. Switchgear-style construction uses drawout circuit breakers, with full-section barriers between compartments, and a heavier-duty bus designed for repeated maintenance withdrawals. Square D Power-Zone 4, Eaton Magnum DS, GE Power Break II, ABB SACE Emax 2, and Siemens WL-frame switchgear all fall in this category. We carry switchgear-style assemblies for data centers, hospitals, and any installation where downtime for breaker maintenance isn't acceptable.\u003c\/p\u003e\n\n\u003ch3\u003eMotor control center ties\u003c\/h3\u003e\n\n\u003cp\u003eMany industrial installations tie a switchboard directly into a motor control center for the plant's motor loads. We stock MCC-tie sections, MCC main breakers, and the bus extensions that connect the two assemblies. If your order pairs a switchboard with an MCC, send both line-ups in one quote request and we'll match the bus rating, short-circuit ratings, and termination plan across the pair.\u003c\/p\u003e\n\n\u003ch2\u003eAmp ratings we build\u003c\/h2\u003e\n\n\u003cp\u003eOur high-margin range is 1600A through 4000A, where manufacturer factory lead times run 20 to 40 weeks and most contractors get burned waiting on a deadline.

Most commercial demand sits in the 480Y\/277V class.

UPS-fed switchboards, generator paralleling gear, and downstream PDU switchboards all push us into the 2500A to 4000A range with drawout breakers and full selective coordination. Redundancy requirements (N+1, 2N) mean orders often come in pairs or quads.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eHospitals\u003c\/strong\u003e demand strict utility approval, ground-fault protection on essential branches, and equipment that can be serviced live wherever possible. We stock the listed service-entrance configurations and have built the dual-source automatic transfer switch ties into adjacent switchgear lineups on emergency builds.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eManufacturing plants\u003c\/strong\u003e tend to specify by amp rating and by what's already installed on-site. Replacement of a failed 2000A main on a Friday afternoon is the kind of call we handle most weeks. MCC ties, oversized neutrals for non-linear loads, and arc-flash labeling all come into the conversation.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eMulti-tenant commercial\u003c\/strong\u003e (office towers, mixed-use retail, hotels) typically lands in the 1600A to 2500A range with sub-metering. Service-entrance switchboards here are often the entire job, with distribution panelboards taking power downstream.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eHigher education and municipal\u003c\/strong\u003e sites usually replace ageing equipment in occupied buildings, which means physical envelope matters as much as electrical spec. We've shipped switchboards in non-standard frames to fit existing electrical room footprints when a manufacturer's stock unit wouldn't physically fit.\u003c\/p\u003e\n\n\u003ch2\u003eConfigurations: front-access vs rear-access, drawout vs fixed-mount\u003c\/h2\u003e\n\n\u003cp\u003e\u003cstrong\u003eFront-access\u003c\/strong\u003e switchboards allow all maintenance from the front of the unit. They take less floor space (no rear working clearance needed) and suit tighter electrical rooms. The trade-off is more limited internal access on larger frames.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eRear-access\u003c\/strong\u003e switchboards require working clearance behind the unit but give technicians full access to lugs, bus connections, and incoming cable terminations. Most service-entrance gear above 2000A is specified rear-access for serviceability.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eDrawout breakers\u003c\/strong\u003e roll out of their compartments on rails for inspection, testing, or replacement without de-energizing the bus. Standard above 2000A and on any switchgear-class assembly. Magnum DS, Power-Zone, Power Break II, Emax 2, and WL all support drawout configuration.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eFixed-mount breakers\u003c\/strong\u003e bolt directly into the structure.
