Overview

NSI Industries ISE155 Pre-Insulated Service Entry Sleeves (SKU: ISE155) are compression-style connectors engineered for fast, tool-assisted installation in aluminum-aluminum and aluminum-copper conductor combinations. Designed to meet ANSI C119.4 standards, these sleeves support conductor ranges from 3/0 to 2 AWG stranded and are rated for 600V maximum applications. The solid center barrier ensures electrical isolation and mechanical integrity, preventing conductor migration and short-circuit risks. These sleeves are ideal for service entrance, branch circuit, and distribution panel terminations where code-compliant, weather-resistant connections are required. Installation requires standard compression tools and dies (e.g., NSI OD581 series), with color-coded sleeves for easy conductor size identification. The 600V rating aligns with NEC 310.15 ampacity tables, ensuring compliance in residential, commercial, and light industrial installations. NSI Industries, a trusted manufacturer in electrical connectors, delivers durable, corrosion-resistant aluminum sleeves that maintain performance in harsh environments. For optimal results, pair with NSI’s recommended compression dies and verify ampacity against current NEC guidelines.
