GROUND BAR KIT-27 POS, NO.14-4

🔌 What it is

The EC3GB27 is a Siemens ground bar kit used inside electrical panels (load centers) to provide a dedicated point for connecting equipment grounding conductors (EGCs).

It is essentially an add-on grounding strip for panels that need more ground terminations.

🧾 What the model means

• EC → Siemens electrical accessory series
• 3GB → Ground Bar family (equipment grounding bar)
• 27 → ~27 grounding terminal positions (varies slightly by panel application)

⚡ What it does

This part:

• Provides a common grounding connection point inside a panel
• Accepts multiple branch circuit ground wires
• Helps maintain proper neutral/ground separation in subpanels
• Mounts directly to Siemens load centers or designated bonding locations
• Supports copper and aluminum conductors (panel-dependent listing)

These ECGB-style bars are used for terminating grounding conductors in Siemens equipment and are UL-listed for panel use.

🏠 Typical uses

• Residential breaker panels
• Subpanels (where separate ground bar is required)
• EV circuit installations
• HVAC / appliance branch circuits
• Panel expansions needing extra ground capacity

🧠 Simple explanation

This is a metal strip installed inside an electrical panel where all the ground wires from circuits get connected together safely.
