A data center E-House can integrate much of the electrical infrastructure needed to receive, transform, distribute, protect, and monitor power. Depending on the project, this may include medium-voltage switchgear, transformers, low-voltage switchboards, UPS equipment, battery systems, power distribution units, protection and control panels, metering, and communications interfaces. Some projects also include supporting HVAC, fire detection, and safety systems. The final equipment list depends on the electrical design, space and heat-load limits, applicable codes, transport constraints, and the boundary between the E-House and the wider data center.
At Pushen, we approach an E-House as a coordinated, prefabricated electrical space rather than a fixed package with the same equipment in every project. We work with buyers and project teams to define the required scope, interfaces, and layout before equipment selection and integration. This guide explains the main equipment options and the decisions that help determine what belongs inside the enclosure.
Integration is not simply a matter of fitting equipment into a container. Buyers should confirm the single-line diagram, operating clearances, heat dissipation, maintenance access, cable routes, environmental conditions, and responsibilities for equipment supplied outside the E-House.
Medium-voltage switchgear may receive power from the utility or an upstream substation and provide switching, isolation, and protection. Depending on the electrical architecture, the E-House may also include metering, protection relays, control circuits, and interfaces for remote operation. The selected switchgear type and ratings must match the project’s system voltage, fault levels, operating method, and local requirements.
Not every E-House needs medium-voltage equipment. Some projects receive power at low voltage or place the medium-voltage switchgear in a separate building. The project team should identify the supply boundary and switching responsibilities early, particularly where utility equipment, generator systems, and data center distribution meet.
Transformers may be integrated when the enclosure has adequate space, access, ventilation, and provisions for heat management. In other designs, transformers are installed outside the E-House to simplify maintenance, manage heat, or meet site requirements. The choice depends on the transformer type, capacity, layout, acoustic and environmental considerations, and the project’s installation strategy.
Low-voltage switchboards distribute power to downstream loads and may include incoming devices, bus sections, feeder protection, metering, and control interfaces. As an example of a project design value—not a universal requirement—a low-voltage system might be specified at 400/230 V AC. Other nominal voltages are used in different regions and facilities, so buyers should provide the project’s actual voltage and frequency requirements rather than assume a standard.
An uninterruptible power supply (UPS) can be installed in an E-House to support continuity between a power disturbance and the availability of an alternate source or other response. The associated battery system may be housed in the same enclosure, in a separate battery room, or in dedicated cabinets, depending on capacity, technology, ventilation, fire strategy, and applicable safety rules. Battery placement should be evaluated as part of the complete system design, not treated as a space-planning detail.
Runtime is determined by the load, battery design, operating conditions, and project requirements. A 5–15 minute autonomy range can be used as an illustrative planning scenario in some designs, but it is not a universal data center requirement or a guaranteed UPS specification. Buyers should define the required load profile and runtime, then ask the supplier and design team to confirm equipment sizing and interfaces.
Downstream distribution may include power distribution units (PDUs), panelboards, or interfaces to overhead or underfloor busway. These components connect the upstream electrical system to IT and facility loads. The E-House scope should state whether distribution beyond the enclosure is included, supplied separately, or only provided with connection provisions.
Protection relays, circuit breakers, meters, control panels, and communication gateways can be integrated to support safe operation and visibility of electrical conditions. Their functions and data points should follow the project’s protection philosophy and monitoring requirements. Confirm communication protocols, network ownership, cybersecurity policies, and responsibility for configuration before procurement.

Where generator systems are part of the facility, the E-House may include generator control interfaces, synchronization or transfer equipment, and related protection, depending on the design. The generators themselves are often located outside the E-House because of their size, exhaust, fuel, and noise considerations. Buyers should define whether the package includes the control interface only or a broader backup-power scope.
Electrical equipment produces heat, so the E-House may require mechanical cooling or ventilation sized for the actual equipment losses and environmental conditions. HVAC selection should account for operating temperatures, equipment requirements, redundancy expectations, and the effects of filters or outdoor exposure. We recommend confirming heat loads with equipment suppliers rather than relying on a generic enclosure estimate.
Fire detection, alarms, emergency lighting, normal lighting, grounding, and access control may also be included or coordinated with the building systems. The required protection and suppression approach depends on the installed equipment, battery technology, jurisdiction, and site fire strategy. The E-House supplier should clearly identify which systems are included, which are by others, and what connections or space allowances are provided.
Large transformers, generators, fuel systems, external cable routes, and downstream IT distribution are often located outside the E-House, although project-specific arrangements vary. Equipment may be excluded because of footprint, heat, maintenance access, safety requirements, or the site’s preferred layout. A responsibility matrix is useful for distinguishing supplied equipment from interfaces and installation work provided by other parties.
Provide the supplier with the single-line diagram or a preliminary power-flow description, incoming supply details, required distribution levels, redundancy concept, and intended load. A project may use 50 Hz or 60 Hz, depending on its location and design, so frequency should be explicitly stated alongside voltage. These values affect equipment selection and compatibility, but they do not by themselves determine the complete system design.
Confirm the available footprint, transport dimensions, lifting points, site access, installation location, ambient conditions, and required service clearances. Ask for equipment heat-loss information and verify that ventilation or cooling can maintain the required conditions. Also consider cable entry direction, internal segregation, future maintenance, and whether modules can be transported and installed in the planned sequence.
Define who supplies each component, who completes cable terminations, and who is responsible for protection coordination, testing, commissioning, and integration with site monitoring. Request layout drawings, equipment schedules, interface lists, and a clear description of assumptions and exclusions. A 24-hour operating cycle is common for data center environments, but the required maintenance and operating arrangements should still be confirmed for the specific project rather than assumed.
A frequent scope gap is assuming that “integrated” means fully commissioned and connected to every site system. The term may refer only to equipment mounted and wired within the enclosure, while external cabling, site testing, network configuration, or utility coordination remains outside the package. Clarify deliverables in the technical specification and commercial quotation before placing an order.
Pushen supports B2B buyers in defining electrical equipment scope and coordinating the package around project-specific requirements. We can review the intended equipment lineup, enclosure arrangement, electrical interfaces, and documentation needs with your engineering and procurement teams. The final configuration should be based on confirmed project data and equipment requirements, rather than an assumed standard package.
To begin a discussion, share your preliminary single-line diagram, supply voltage and frequency, target load, redundancy concept, site conditions, and preferred delivery scope. We can then help identify which equipment is suitable for integration, which items may be better located externally, and what information is needed to develop a project-specific proposal.
A data center E-House can integrate medium-voltage switchgear, transformers, low-voltage switchboards, UPS and battery systems, downstream distribution equipment, protection and monitoring panels, and supporting systems such as HVAC and fire detection. The right combination depends on the power architecture, site conditions, equipment capacity, safety requirements, and the agreed supply boundary. Buyers should define electrical ratings, load and runtime needs, cooling, interfaces, and exclusions before finalizing the package. With those inputs prepared, contact Pushen to review your equipment scope and develop a practical E-House configuration for your project.
