Industrial Power Solutions – Custom Switchgear & MCC Systems Engineered for Reliability and Scale
At Pinnacle Power & Controls, we design and build UL‑listed and ANSI C37‑certified power solutions for industries that demand the highest levels of performance and uptime. Our portfolio includes custom low‑ and medium‑voltage switchgear, prefabricated E‑House systems, modernization and integration services, and turnkey installation capabilities, all engineered and built in the USA.
Whether you’re powering a 480 V manufacturing line, a 15 kV utility interconnect, or a remote data centre, we deliver fit‑to‑spec solutions that are engineer‑to‑engineer designed and rapidly delivered. From a new distribution line‑up to a factory‑integrated E‑House or a complete retrofit of your legacy gear, our team provides the expertise and support you need to keep your operations safe, scalable, and compliant.
Why Reliable Power Distribution Matters
In industrial facilities, power distribution is the foundation that keeps processes running safely and efficiently. Well‑designed switchgear allows electrical energy to be controlled, protected, and isolated without shutting down production or compromising worker safety. From manufacturing lines and data centers to water treatment and renewable energy operations, reliable switchgear must deliver four essential qualities:
- Continuous uptime – Redundant feeders, main‑tie‑main configurations, and selective coordination keep your facility online even when faults occur.
- Safety – Compartmentalized sections, arc‑flash mitigation, and fault isolation protect personnel and equipment during normal operation and maintenance.
- Scalability & growth – Modular sections, draw‑out breakers, and prefabricated E‑House options make it easy to expand or reconfigure as your needs change.
- Compliance & assurance – Adhering to UL 891, ANSI C37, NEC, and NFPA 70E standards ensures your system remains code‑compliant and insurable.
By prioritizing reliability and safety in your power distribution design, you protect your investment, support future growth, and ensure uninterrupted operation of your critical infrastructure.

Below you’ll find a summary of the power distribution systems and services we offer. Each category links to a detailed service page where you can learn more about technical specifications, options, and typical applications.
Low‑Voltage Switchgear (UL 891)
Pinnacle’s UL 891‑listed low‑voltage switchgear is custom‑engineered for distribution, control, and protection up to 600 V. Whether you need a main‑breaker, main‑tie‑main, transformer, or multi‑source configuration, our assemblies provide robust protection and easy maintenance.
- Voltage & ratings – 240/120 V single‑phase or 480/277 V three‑phase; standard 400 A–5 000 A ratings with higher capacities available on request.
- Enclosures – Indoor and outdoor NEMA 1, 3R, or 12 options for dust, moisture, and weather protection.
- Bus systems – Choice of copper or aluminum bus bars, braced to handle short‑circuit currents with optional insulated bus for enhanced safety.
- Arc‑flash mitigation – Segmented compartments, relays, and barriers help reduce incident energy and support NFPA 70E compliance.
- Smart communications – Integrated metering, PLC/SCADA connectivity, and remote monitoring enable diagnostics, automation, and smart‑grid integration.

Prefabricated Switchgear Buildings (E‑Houses)
To accelerate deployment and minimise on‑site work, we manufacture factory‑integrated switchgear buildings — also known as E‑Houses — that house your electrical gear, control panels, HVAC and protection systems. Built to your one‑line diagram and voltage class, each unit arrives fully wired, tested and ready to energise.
Types of E‑Houses include:
- Modular multi‑room buildings – Multi‑section enclosures for large switchgear line‑ups and integrated control gear, designed for segmentation, safety zoning and scalability.
- Walk‑in switchgear enclosures – Climate‑controlled buildings for permanent facilities such as substations, water plants and manufacturing control rooms.
- Containerised E‑Houses – Reinforced ISO containers outfitted as switchgear rooms for transport, temporary projects and harsh environments.
- Skid‑mounted switchgear rooms – Portable, pre‑wired structures mounted on skids for rapid deployment in oilfields, modular sites or emergency power projects.
Every E‑House includes lighting, metering, relays, SCADA integration, HVAC and fire suppression, and is FAT‑tested for immediate drop‑in installation.

Switchgear Modernization & Integration
Modernizing legacy switchgear keeps your facility safe, reliable and compliant. Our UL‑listed modernization services update obsolete components and integrate modern protection and control technologies while retaining your existing footprint.
- Breaker retrofits & upgrades – Replace oil or obsolete breakers with modern vacuum or air‑insulated types, available in draw‑out or fixed‑mount designs.
- Busbar & conductor improvements – Upgrade to higher‑rated copper bus and improved bracing for better fault‑current handling.
- Relay & protection modernization – Install digital relays with arc‑flash mitigation, fault detection and SCADA‑ready communications.
- SCADA & metering integration – Integrate meters, PLCs and network communications for real‑time monitoring and remote control.
- Control panel integration – Coordinate your switchgear with generator ATS, PLC panels and MCCs for unified operation.
Unsure whether to retrofit or replace? Our Retrofit vs Replace guide helps you compare budgets, downtimes and code requirements to find the right solution.

Switchgear Testing & Commissioning
Ensuring that your gear operates exactly as designed requires rigorous testing before shipment and comprehensive commissioning in the field. Our QA program covers the entire lifecycle from FAT through on‑site startup.
- Factory acceptance testing (FAT) – Pre‑shipment tests cover wiring checks, relay verification, labeling, torqueing, and documentation.
- Insulation & dielectric testing – Verify conductor insulation and dielectric strength for code compliance and reliability.
- Breaker functionality & protection coordination – Validate trip units, timing, and selective coordination to handle faults properly.
- Arc‑flash mitigation testing – Confirm that barriers, relays,s and system configurations reduce incident energy exposure.
- SCADA & metering validation – Ensure that relays, PLCs, HMI,s and meters are configured and communicating correctly.
- On‑site startup & commissioning – Support your team with grounding checks, energization, interlock verification, and operator training.
