Ilsco SPAR-500 Insulated Connector 500 Mcm 3/0 Awg

Product Description

The ILSCO SPAR-500 is an insulated tap connector designed to join a 500 MCM main conductor to a 3/0 AWG tap conductor without interrupting service. The connector's insulated housing protects the splice point from contact and environmental exposure, making it suitable for use in overhead, underground, or enclosed service entrance applications. Electricians use this connector when making permanent tap connections on larger feeders in residential, commercial, and light industrial systems. The unit ships ready to install and does not require special tooling beyond standard lineman hand tools.

This connector is intended for use in high-ampacity feeder and service entrance wiring where a 500 MCM main run requires a 3/0 AWG branch tap. Typical applications include service entrance taps, feeder splices in transformer secondary circuits, and utility-side distribution work. The insulated design allows the finished connection to remain exposed without the need for additional tape or heat shrink, reducing labor time at the splice point.

Key Features

• Accepts 500 MCM main conductor and 3/0 AWG tap conductor
• Insulated housing eliminates need for additional taping or sleeving after installation
• Suitable for service entrance, feeder tap, and distribution splice applications
• Compact form factor fits in tight conduit bodies and enclosures

Compatibility

Designed as an OEM-style insulated tap connector for use with 500 MCM main conductors and 3/0 AWG tap conductors in standard electrical feeder and service entrance assemblies.

Installation Notes

Installation must be performed by a licensed electrician in accordance with the National Electrical Code (NEC). De-energize and lock out the circuit at the upstream overcurrent protective device before making any connections. Verify conductor sizes match the connector's rated range before applying torque to any fasteners. Inspect the insulated housing for cracks or damage before and after installation.
