Solar grounding connector speeds installation of panel frames
A new solar grounding connector from Tyco Electronics shortens the installation time of a ground wire to a solar panel frame. The threaded connector is inserted through a hole in the frame and uses two nuts to secure the connection. The connector handles 6 and 8 AWG (13.3 and 8.4mm2) solid, uninsulated copper wire.
In connecting to the frame, the connector body and the one-piece lock washer nut penetrate the surface of the aluminium frame to create a reliable ground path.
Greg Paukert, product manager, states: "As photovoltaic applications become more widespread, the industry is looking for ways to reduce both component costs and installation costs, while increasing reliability. Our new grounding connector is an outstanding example of an easy-to-use, fast-to-install solution that helps lower costs."
In the six-second short-term current test, the connector handles 1530A with 6 AWG ground wire. With 8 AWG ground wire, a four-second test concludes that the connector handles 1180A. The connection is also said to be mechanically robust: in UL 486A/B pull-out testing, the connector provides 100 pounds (45.3kg) with 6 AWG wire and 90 pounds (40.8kg) with 8 AWG wire.
