MM LUG 4S/6C 125A 4J OH/UG RG

MM LUG 4S/6C 125A 4J OH/UG RG – Product Description

🔌 What it is

A main lug / meter-main style electrical termination assembly used to connect and distribute service power (typically between utility service conductors and a panel or subpanel).

🧾 What the shorthand means

• MM LUG → Main Lug (no main breaker; incoming power lands on lugs)
• 4S/6C →
  • 4 spaces (or positions depending on configuration)
  • supports up to 6 circuits (layout-dependent designation)
• 125A → 125-amp service rating
• 4J → enclosure/jaw or model series designation (manufacturer-specific code)
• OH/UG → Overhead / Underground feed compatible
• RG → Ring-style meter / ringed enclosure (or rain-gutter/rated housing depending on manufacturer shorthand)

⚡ What it does

This type of equipment:

• Receives incoming utility power (overhead or underground service)
• Provides main termination points (lugs) for service conductors
• Distributes power onward to a panel or branch system
• Acts as a service entrance or meter-main component

🏠 Typical uses

• Residential service entrance equipment
• Small homes or accessory buildings with 125A service
• Meter-main combinations feeding a load center
• Utility-approved outdoor power distribution setups

🧠 Simple explanation

This is a 125-amp service connection box that accepts utility power (overhead or underground) and feeds it into a home or subpanel using main lugs instead of a built-in breaker.

🔧 Key takeaway

• It is part of the service entrance system, not a branch breaker
• Uses main lugs instead of a main breaker
• Supports 125A electrical service distribution
• Designed for utility meter and feed connections
