Nsi Industries G-15 Conduit Ground Clamp 8-4/0 Awg 2.5-4 in Ips

Product Description

The NSI INDUSTRIES G-15 is a heavy-duty silicon bronze conduit ground clamp designed to bond grounding conductors to metallic conduit or pipe in electrical grounding applications. The silicon bronze body provides corrosion resistance in demanding environments. It accepts conductors from 8 AWG through 4/0 AWG stranded and fits IPS pipe sizes from 2-1/2 to 4 inches. Connection is made with a two-screw pipe attachment and a two-screw wire connector, giving the installer a secure, vibration-resistant bond. This clamp carries UL approval and is sold as an individual unit. Licensed electricians and grounding specialists install this hardware as part of building or equipment grounding electrode systems.

The G-15 is suited for residential, commercial, and light industrial electrical installations where a reliable conduit-to-ground-conductor connection is required. It is commonly used at service entrance equipment, panelboards, and equipment grounding points where conduit serves as part of the grounding electrode system. The two-screw pipe connection ensures positive contact on pipe surfaces within the specified IPS size range, and the two-screw wire terminal accommodates the wide conductor range without requiring a separate lug or adapter.

Compatibility

Designed as an OEM-style grounding clamp for use on metallic conduit and IPS-sized pipe within the 2-1/2 to 4 inch range, compatible with 8 to 4/0 AWG stranded grounding conductors per the specifications stated by the manufacturer.

Installation Notes

Installation should be performed by a licensed electrician in accordance with applicable NEC requirements for grounding electrode conductors and equipment grounding. De-energize the circuit and verify absence of voltage before making any grounding connections. Clean the pipe surface at the clamp contact point to ensure low-resistance metal-to-metal contact. Tighten both pipe screws and both wire connector screws firmly with an appropriate screwdriver or nut driver; do not overtighten to the point of cracking the bronze body.
