ILSCO, a Cincinnati-based electrical connector manufacturer, has released two new connectors for solar module grounding: SGB-4 and GBL-4SS. The company says these connectors are designed to prevent galvanic reactions and enhance conductivity.
The SGB-4 connector body has extruded serrations for breaking the anodized finish on photovoltaic modules and frames. The serrations in the wire binding break corrosion on the grounding wire, which means that no surface preparation is required for the PV module, frame or ground wire, the company notes. The clamp-on design requires no mounting holes; the connector simply clamps onto the frame of the solar panel.
The UL 467-listed and CSA-certified aluminum connectors accommodate 4-14 AWG and are dual-rated for copper or aluminum conductors. They are electro-tin plated for low contact resistance, ILSCO adds.
