U‑type copper die set intended for creating classified crimps on 300 MCM copper conductors when used with a compatible compact crimper and connectors. Dies include permanent markings and color coding to identify size; the completed crimp leaves an imprinted wire size on the connector for inspection. Crimper and connectors sold separately; refer to the crimper user manual for compatible die/connector combinations.
Project Ideas
Business
Mobile UL-Classified Crimping Service
Offer on-site crimping for contractors and facility managers who need 300 MCM terminations in tight schedules or confined spaces. Bring the DEWALT compact crimper and 300 MCM U-die with a stock of listed lugs (per the compatibility chart). Provide photo documentation of each crimp’s die impression, conductor size, and location, plus a report for inspectors and project records.
Custom 300 MCM Cable Assemblies
Set up a small shop that fabricates made-to-order 300 MCM copper cable assemblies: service jumpers, generator leads, solar/battery interconnects, and switchgear whips. Use the U-die to produce consistent UL Classified crimps and ship assemblies with labeled heat shrink, torque specs for hardware, and a quality checklist including the die-imprinted size photo for every end.
Temporary Power Feeder Rentals
Build and rent rugged 300 MCM feeder sets for events, outages, or construction sites. The die-stamped connector markings help customers and inspectors verify conductor size quickly. Bundle rentals with inspection/recertification between uses, and offer an optional on-site repair/re-crimp service to keep fleets compliant and reduce downtime.
Crimp Audit and Remediation
Provide a service that audits large-conductor terminations in plants, data centers, and commercial buildings. Identify non-compliant or degraded connections, then remediate by installing listed lugs and applying UL Classified crimps with the 300 MCM U-die. Deliver before/after photos, pull-test or torque verification where applicable, and a compliance report for facility records.
Hands-On Crimp Training Workshops
Run half-day workshops for apprentices and electricians covering die selection, color coding, and inspection criteria. Each participant completes several 300 MCM crimps using the compatible compact crimper and the U-die, labels them, and takes home a sample coupon with the die-imprinted size. Sell a companion kit (heat shrink, sample lugs, inspection checklist) to generate additional revenue.
Creative
Off-Grid Power Cart Build
Design a rolling 48V battery/inverter power cart with proper high-current terminations using 300 MCM copper feeders between the battery bank, main DC disconnects, shunt, fuse block, and inverter. Use the DCE310 compact crimper with the 300 MCM Copper U-Die Set and listed connectors (per the crimper’s compatibility chart) to make UL Classified crimps; the die’s imprinted wire size helps with inspection and labeling. Add color-matched heat shrink to mirror the die’s color code and include a clear cable schedule placard for a polished, professional build.
Stage/Film Power Feeder Set
Build professional-grade 300 MCM feeder cables for event, stage, or film power distribution (e.g., cam-lock leads to distro racks). Use the U-die to create consistent, inspection-ready crimps that stamp the wire size on each connector for easy verification in the field. Pair with rugged jackets, strain reliefs, and serialized tags so crews can quickly inventory and confirm the correct size and length at a glance.
Crimp Quality Demo Board
Create an educational display that contrasts correct UL Classified crimps against common mistakes. Mount sample lugs and short cable coupons showing proper die selection (using the die’s laser-etched markings and color coding), completed crimps with the imprinted wire size, and examples of mis-crimps for training apprentices or upskilling crews. Add notes on visual inspection points and pull-test results to make it a practical shop resource.
Copper Cable Kinetic Sculpture
Repurpose sections of retired 300 MCM copper cable to build a kinetic or modular sculpture. Use crimped lugs as structural ‘nodes’ that bolt to custom plates, showcasing the die’s stamped size as an intentional design motif. The heavy cable’s natural bend radius can form graceful arcs; integrate backlighting to make the stamped markings pop and add an industrial-art aesthetic.
EV/Industrial Battery Harness Upgrade
Fabricate a high-current harness for an EV conversion, large UPS, or industrial forklift battery system where 300 MCM conductors are appropriate. Crimp listed lugs with the 300 MCM U-die to ensure low-resistance, inspection-friendly terminations between the battery, contactors, busbars, and inverter/controller. The imprinted size on each connector simplifies documentation and future maintenance.
