Panduit LAMA2-14-C Pan-Lug Aluminum Mechanical Compression Lug
The Panduit LAMA2-14-C is a tin-plated aluminum mechanical lug designed for terminating 2 AWG stranded aluminum or copper conductors to 1/4" stud bus bars, breakers, and terminal blocks in battery backup systems, UPS installations, and low-voltage power distribution panels. Rated for 600V and 90°C per cULus standards, this single-hole barrel lug delivers code-compliant crimped connections in datacenter, telecom facility, and industrial power applications where aluminum feeder runs terminate at copper infrastructure. Each package contains 100 lugs ready for hydraulic or mechanical crimping tools.
Key Features
- 2 AWG wire range for aluminum or copper stranded conductors
- 1/4" (6.35mm) stud hole for standard breaker and bus bar mounting
- Tin-plated barrel inhibits galvanic corrosion at dissimilar-metal junctions
- cULus Listed for 600V systems and 90°C conductor temperature ratings
- Single compression point reduces installation time vs. multi-indent lugs
- 100-piece packaging for mid-size battery bank and panel buildouts
The LAMA2-14-C uses a tin-plated aluminum barrel that accommodates the thermal expansion coefficients of both aluminum feeder wire and the copper or aluminum terminal studs found on modern circuit breakers and distribution blocks. The 0.55" height and 0.5" width barrel profile fits standard crimping dies for Panduit CT-series and equivalent hydraulic compression tools. The 1/4" mounting hole accepts NEMA-standard terminal studs without adapter hardware, and the 1.17" overall length provides adequate wire bend radius per NEC 300.34 for conductors exiting the lug tongue. Tin plating on both the barrel interior and stud contact surface minimizes oxidation in the 60-120°C operating environments typical of fully loaded electrical enclosures, extending connection life beyond bare aluminum lugs that form insulating oxide layers under current cycling.
Field techs installing 48VDC battery strings in telecom central offices and -48VDC plants use the LAMA2-14-C to land 2 AWG negative returns from battery modules to the common ground bus, where the tin coating prevents the voltage drop creep that bare aluminum develops as oxide accumulates. In three-phase UPS bypass panels, the lug terminates 2 AWG aluminum neutral jumpers to isolated ground bars, maintaining the 600V isolation rating required by NEC 647.6 for IT equipment branch circuits. The single-barrel design works in tight enclosures where multi-barrel lugs interfere with adjacent breaker handles—the 12.7mm width leaves clearance for finger-safe terminal covers on 15mm-pitch DIN-mount breaker blocks. Crimping with 8-12 tons of force per the Panduit crimp spec creates gas-tight contact that meets the 15-microhm maximum resistance targets in IEEE 1375 for stationary battery interconnects.
cULus Listing under UL 486A-486B confirms the lug's suitability for building wire terminations in NEC-governed installations, covering both the 600V voltage rating and the 90°C conductor insulation temperature that applies when using THHN/THWN-2 wire in ambient temperatures up to 40°C with full-load current derating. The 100-count package matches the lug quantities needed for a 25-string 48VDC battery plant (4 lugs per string: positive/negative at battery end, positive/negative at bus end), reducing packaging waste compared to 10-packs while avoiding the inventory commitment of 500-piece contractor boxes for smaller datacenter retrofits.
