Switchgear Manufacturer and Full-Service Power Systems Partner
Coastal Power Systems is a custom switchgear manufacturer (with over 30 years experience) specializing in UL 1558 switchgear, UL 891 switchboards, and UL 67 panelboards for industrial facilities, utilities, data centers, power generation plants, petrochemical operations, and critical infrastructure projects.
Manufacturing switchgear is at the core of what CPS does, however, equipment manufacturing is only one part of a successful electrical power project. EPC firms, consulting engineers, facility owners, contractors, distributors, and procurement teams increasingly need a manufacturing partner (like CPS) that can also support equipment design, system studies, protection and control integration, factory testing, commissioning, maintenance, modernization, and long-term field service.
CPS combines switchgear manufacturing expertise with comprehensive electrical engineering and lifecycle support. This integrated approach helps customers reduce coordination between vendors, address technical issues earlier, improve project accountability, and obtain long-term support from a company that understands how the equipment was designed and built.

Low-Voltage Switchgear Built for Critical Power Applications
Low-voltage switchgear controls, protects, and distributes electrical power within facilities where equipment reliability, personnel safety, maintainability, and continuity of operations are essential. CPS manufactures custom switchgear for applications requiring power circuit breakers, advanced protective relaying, metering, communications, control systems, selective coordination, and high short-circuit withstand capability.
Unlike standard catalog equipment, custom low-voltage switchgear can be configured around project-specific electrical requirements, available floor space, utility requirements, cable-entry limitations, breaker arrangements, bus ratings, future expansion needs, protection schemes, custom enclosure colors, and operating procedures.
As a switchgear manufacturer with engineering and field-service capabilities, CPS evaluates equipment requirements within the broader context of the electrical system. This helps ensure the finished equipment supports the project’s protection objectives, operational requirements, maintenance strategy, and long-term reliability goals.
UL 1558 Switchgear Manufacturer
UL 1558 switchgear is commonly specified for low-voltage power distribution systems requiring draw-out power circuit breakers, compartmentalized construction, advanced protection, higher fault-current capability, and maintainable equipment configurations.
CPS manufactures UL 1558 switchgear for data centers, power generation facilities, utilities, industrial plants, petrochemical operations, water and wastewater facilities, transportation infrastructure, and other critical applications. Equipment can be engineered to support main-tie-main arrangements, multiple mains, generator paralleling interfaces, automatic transfer schemes, protective relays, metering, communications, control power, and future expansion.
Project requirements vary widely. CPS works with engineers, EPC contractors, facility owners, and procurement teams to evaluate one-line diagrams, equipment specifications, available space, system ratings, protective-device requirements, breaker arrangements, control logic, communications protocols, and testing expectations before manufacturing begins.
This collaborative process helps identify design conflicts early and reduces the risk of costly changes during installation or commissioning.
UL 891 Switchboard and UL 67 Panelboard Manufacturer
CPS also manufactures UL 891 switchboards and UL 67 panelboards for applications that do not require the construction or power circuit breaker configurations associated with UL 1558 switchgear.
UL 891 switchboards are commonly used for service entrance, main distribution, feeder distribution, and secondary power distribution applications. They may incorporate molded-case or insulated-case circuit breakers, metering, surge protection, control systems, and application-specific bus arrangements.
UL 67 panelboards are used for branch-circuit and distribution applications requiring compact, organized, and accessible circuit protection. Custom panelboard configurations can help address unusual voltage requirements, circuit arrangements, space limitations, enclosure needs, and project-specific labeling or documentation requirements.
By manufacturing multiple categories of power distribution equipment, CPS can help customers select the appropriate equipment type for each part of the electrical system instead of attempting to force every application into a single standardized solution.
Why Selecting the Right Switchgear Manufacturer Matters
Switchgear and electrical power distribution equipment often remain in service for decades. Decisions made during engineering and procurement can affect equipment reliability, personnel safety, maintenance costs, outage duration, spare-parts availability, modernization flexibility, and future expansion throughout the equipment lifecycle.
Initial purchase price is important, but it should not be the only consideration. Equipment accessibility, breaker interchangeability, protection capabilities, communications integration, bus configuration, cable access, documentation quality, testing requirements, and future modification options can have a much greater effect on long-term ownership costs.
The right switchgear manufacturer should understand both the equipment and the electrical system in which it will operate. That includes fault-current requirements, protective-device coordination, arc-flash considerations, grounding, control power, operational sequences, maintenance access, commissioning requirements, and long-term modernization needs.
CPS approaches switchgear manufacturing as part of a complete power-system strategy rather than as an isolated fabrication process.
Custom Switchgear Versus Standard Catalog Equipment
Standard catalog equipment may be appropriate when project requirements are straightforward and available configurations closely match the intended application. However, industrial facilities, utility systems, data centers, power plants, and retrofit projects frequently involve conditions that standard equipment cannot address efficiently.
Existing facilities may have limited floor space, unusual cable-entry locations, restricted access, existing bus or conduit arrangements, utility-specific requirements, obsolete equipment interfaces, or outage constraints. New facilities may require specialized protection schemes, communications integration, redundant power paths, generator controls, selective coordination, or planned future expansion.
Custom switchgear allows these requirements to be addressed during equipment design instead of through extensive field modifications after shipment. This can simplify installation, reduce project risk, improve maintainability, and provide a more practical foundation for future expansion or modernization.
CPS can also evaluate custom equipment within the context of existing electrical infrastructure, helping customers identify where new switchgear must interface with older equipment, protection systems, controls, and facility operating procedures.
A Full-Service Switchgear Manufacturer for EPC Projects
EPC firms often manage competing priorities involving technical requirements, equipment cost, project schedule, vendor coordination, constructability, testing, documentation, and customer expectations. Switchgear can affect nearly every phase of project execution, from engineering and procurement through installation, energization, and final acceptance.
CPS supports EPC firms and consulting engineers through equipment application assistance, specification review, system studies, equipment design, protection and control integration, factory testing, commissioning support, and field service.
Working with a full-service switchgear manufacturer gives project teams a single technical resource capable of addressing issues that cross the boundaries between equipment manufacturing, system engineering, protection, controls, testing, and field implementation.
This integrated approach can help reduce communication gaps, identify interface issues earlier, simplify technical coordination, and improve accountability throughout the project.
Engineering Support for Switchgear Projects
Switchgear performance depends on the electrical system surrounding it. Equipment ratings, breaker selection, protective relay settings, control schemes, grounding, available fault current, selective coordination, and arc-flash performance must be evaluated together.
CPS engineering capabilities allow switchgear decisions to be supported by system-level analysis. Depending on project requirements, CPS can assist with short-circuit studies, protective-device coordination studies, arc-flash studies, load-flow analysis, equipment application, protection and control design, one-line diagram review, and modernization planning.
This engineering perspective is especially valuable for complex industrial projects, existing facilities, utility interconnections, generator applications, and systems where new equipment must coordinate with aging infrastructure.
Factory Testing and Quality Verification
Factory testing verifies that manufactured equipment conforms to approved drawings, project specifications, control requirements, and applicable production procedures before shipment.
Testing activities may include visual and mechanical inspection, wiring verification, control-function testing, breaker operation, protective-relay checks, metering verification, insulation-resistance testing, control-power verification, interlock checks, and other project-specific tests.
For complex equipment, factory acceptance testing can also provide customers, engineers, and EPC representatives with an opportunity to review the completed equipment, verify functional requirements, and resolve issues before the switchgear arrives at the project site.
Resolving technical issues during factory testing is generally more efficient than discovering them during installation or energization.
Commissioning, Maintenance, and Lifecycle Support
Manufacturing is only the beginning of the equipment lifecycle. Long-term performance also depends on proper installation, commissioning, maintenance, troubleshooting, modernization, and future system changes.
Unlike manufacturers that focus only on equipment production, CPS can continue supporting the electrical system after shipment. Services include engineering studies, NETA-guided testing, commissioning, preventive maintenance, troubleshooting, breaker services, protection and control upgrades, switchgear modernization, emergency response, and asset-management support.
Because CPS understands how power distribution equipment is designed, manufactured, tested, installed, and maintained, customers can obtain support from a partner that sees the entire lifecycle rather than only one phase of it.
This lifecycle perspective is particularly valuable for facilities where outages carry substantial operational, safety, production, or financial consequences.
