The MOROSO 90318 is a size 4 copper split bolt connector used to join electrical conductors in a secure, low-resistance connection. Split bolt connectors are a standard solution for splicing wire-to-wire or wire-to-tap applications in electrical distribution, grounding, and bonding work. The copper construction provides excellent conductivity and corrosion resistance. Licensed electricians and experienced electrical contractors install this type of fitting in residential, commercial, and light industrial wiring applications where a reliable mechanical connection is required.
The 90318 is suited for use in conductor splicing and tap applications where a size 4 fitting is required. It is commonly installed in junction boxes, panel work, and grounding assemblies. Copper split bolts of this size are a standard component in electrical rough-in and service work across residential and commercial projects.
Designed as an OEM-style replacement fitting for size 4 copper split bolt connector applications in standard electrical conductor splicing and grounding installations.
Installation should be performed by a licensed electrician in accordance with applicable NEC requirements. Always de-energize and lock out the circuit before installing or servicing split bolt connectors. Ensure conductors are clean and properly stripped before seating in the connector. Wrap the completed connection with listed electrical tape or an approved insulating cover as required by code.
