Protective Cover for Split-Bolt Connectors

This plastic cover fits split-bolt connectors used in electrical wiring. It protects connections for tap wires from 14 AWG to 4 AWG and run wires from 8 AWG to 4 AWG. The cover is rated for a maximum voltage of 600 V AC. It suits electricians and maintenance staff insulating standard bolted joints.

Simple Push-On Installation

The cover slides over the completed split-bolt connection without tools. Its hex-head compatibility aligns with the connector profile for a secure fit. Installers must verify wire sizes fall within the 14 to 4 AWG tap range and 8 to 4 AWG run range. Oversized conductors or damaged connector threads will prevent proper seating.

UL-Listed for 600 V AC Applications

The cover meets UL 468A, UL 468B and UL 486D standards for wire connectors. It is RoHS compliant and restricted from sale in certain states. The plastic material provides basic insulation but is not rated for continuous outdoor exposure or temperatures beyond the connector limits. Buyers needing higher voltage ratings or environmental sealing must select a different product.
