Burndy introduces aluminum lay-in lugs for solar applications
By Renée Francoeur
February 21, 2017 – Burndy’s new additions to their grounding product line include aluminum lay-in lugs, suitable for solar panel applications.
The connectors are for use with frames with a maximum thickness of 1/4 in. or for cable to bus or cable to steel connections where the lay-in feature is necessary.
Manufactured using “high-strength” aluminum alloy, these connectors have the versatility to be used with aluminum and copper conductors, Burndy notes. The serrations are provided to establish better contact and cut through oxidation, ensuring low contact resistance and high conductivity, it adds. The anodization on aluminum rails is nonconductive and electrical current cannot pass through this layer. Burndy says its cup point screw penetrates this layer, allowing current to flow into the aluminum connector and consequently current flows to the conductor.
The connectors are UL467- and UL2703-listed and accommodate copper cables from 14AWG to 6AWG and aluminum cables from 12AWG to 6AWG. They are also available in bulk.
