Transformers
Pole-mounted, pad-mounted, and compact substation transformers for every distribution need. Available in standard and custom kVA ratings and voltage configurations.
Control Panels
Custom-engineered control panels for industrial automation, motor control centers, and process monitoring. Factory-wired, tested, and programmed before shipment.
Feeder Pillars
Outdoor LV distribution pillars for commercial and utility applications — weatherproof, tamper-resistant, fully customizable bus and breaker configuration.
Accessories
Surge arrestors, LV & MV circuit breakers, protective relays, junction boxes, and cable termination kits for complete system protection up to 36kV.
Built Different.
Built to Last.
Every unit we make is engineered to your exact spec, assembled in-house, and fully factory-tested before it leaves Kingston, TN.
UL 891 Listed
Our low-voltage switchboards are UL 891 listed under UL File E539785 — independently evaluated, helping AHJ approval go smoothly.
Arc Flash Mitigation
Zone-selective interlocking, passive arc-resistant designs, and arc-flash detection relays reduce incident energy — meeting NFPA 70E and OSHA requirements.
SCADA & BMS Ready
Modbus RTU/TCP, DNP3, and BACnet communication ports are standard options — integrate seamlessly with your existing BMS or SCADA platform out of the box.
Custom-Engineered to Spec
No catalogue compromise. We take your one-line diagram and fault study — then engineer a lineup that fits exactly. Custom bus heights, widths, and finishes available.
100% Factory Tested
Every lineup undergoes hi-pot testing, contact resistance measurement, relay functional testing, and complete operational verification before shipping.
Project-Specific Lead Times
Manufactured in Kingston, TN — domestic production means no import delays and direct engineering access throughout your project. Lead times are quoted per project from approved drawings.
Field Services
NETA-level testing, commissioning, and 24/7 emergency response — delivered by certified technicians with switchgear and transformer expertise.
Testing & Electrical Maintenance
NETA-compliant insulation, contact resistance, infrared, and Doble testing — paired with preventive maintenance, breaker servicing, and corrective work in a single coordinated visit.
Commissioning & Pre-Commissioning
Pre-energization checks, end-to-end relay testing, control logic verification, and live-system commissioning with NETA-format documentation and AHJ sign-off support.
Engineering & Arc Flash Studies
Short-circuit, coordination, and load flow analysis paired with arc flash risk assessments, PPE recommendations, safety labeling, and staff training programs per NFPA 70E and IEEE 1584.
Switchgear Maintenance & Retrofit
Preventive and corrective maintenance for LV and MV switchgear — breaker racking, contact inspection, lubrication, and full functional verification. Retrofit and replacement sections available.
24/7 Emergency Response
On-call support for outages, breaker failures, and transformer faults. We carry critical spare parts for common LV and MV switchgear platforms for rapid repair and restoration.
Transformer Testing & Maintenance
Doble power factor, turns ratio, insulation resistance, and oil testing for distribution and power transformers. Thermal imaging and load tap changer maintenance included.
Built for the Industries That Can't Afford Failure
From data centers to renewable energy plants, our switchgear powers the facilities where downtime costs millions and safety is non-negotiable.
Engineered for Every Mission-Critical Sector
From hyperscale data centers to remote mining sites, AK&J Electric switchgear is purpose-built for the industries where reliability, safety, and uptime are non-negotiable.
Data Centers & Mission-Critical Facilities
High interrupting ratings, redundancy, and SCADA integration for facilities where downtime is not an option.
Utilities & Renewable Energy — Solar, Wind & Battery Storage
Inverter-grade protection, collection switchgear, and MV integration for clean energy infrastructure.
Industrial & Manufacturing Plants
Robust LV/MV distribution with arc-flash protection for heavy production environments.
Healthcare, Universities & Public Infrastructure
Redundant, code-compliant power distribution for life-safety and critical institutional loads.
EV Charging Infrastructure & Utilities
Scalable switchgear solutions for fleet depots, public charging networks, and utility substations.
Oil & Gas
Rugged LV/MV distribution and control equipment for upstream, midstream, and downstream facilities, engineered to project hazardous-area requirements.
Military & Defense
Mission-critical redundant power systems and hardened switchgear for secure base infrastructure.
Mining & Aggregates

From One-Line to Energized
Every AK&J Electric project follows a proven engineering and manufacturing process — so what arrives on site is ready to energize, code-compliant, on schedule.
Engineering & Design
One-line review, fault study, protection coordination, and stamped shop drawings. We engineer the lineup before a single component is ordered.
Procurement
Breakers, bus, relays, enclosures, and accessories sourced from approved suppliers to meet the listing or project specification, with full traceability.
Assembly & Testing
Skilled technicians assemble each section to approved drawings. Hi-pot, contact resistance, relay, and full functional testing performed before shipping.
Delivery & Commissioning
Turnkey delivery and on-site commissioning by our field service team. Full NETA acceptance test documentation provided at handover.
"At AK&J Electric, every lineup is built to its listing or specification and factory-tested, because safety and reliability are non-negotiable, and so are our standards."
Trusted by Engineers & Contractors
From data centers to renewables, project teams rely on AK&J Electric for precision-built switchgear, on-time delivery, and responsive field service.
“We brought AK&J in on a tight LV switchgear package and they delivered ahead of schedule with clean factory test reports. Their engineer flagged a coordination gap on our one-line that everyone else had missed — that one catch saved us a change order in the field.”
“We sourced MV cable junction boxes, protective relays, and spares for the plant through AK&J. Pricing was fair, lead times held, and everything arrived properly tagged and documented. Made our shutdown planning a lot easier.”
“They turned around our arc flash study and on-site NETA testing in about two weeks. Documentation was clear, the crew was professional on site, and we tied in without any unplanned downtime. Exactly what we needed.”
