Square D PK7GTA Load Center Ground Bar Kit

Overview

The PK7GTA is a compact, seven-terminal equipment ground bar designed for use with Square D QO and Homeline load centers. It provides a reliable, code-compliant grounding point for up to seven conductors and is ideal for residential, commercial, and light industrial panel installations.

Key Features

• Terminal Capacity: Accommodates 7 grounding conductors

• Conductor Size Range:

  • Copper: #14 to #4 AWG

  • Aluminum: #12 to #4 AWG

• Dimensions:

  • Length: Approximately 2.88 inches (73 mm)

  • Height: ~0.437 inches

  • Depth: ~0.312 inches

• Compatibility: Fits QO and Homeline load centers (especially PK-type), commonly used in subpanel configurations

• Construction: Tin-plated aluminum bar with pre-threaded holes

• Included Hardware: Comes with two mounting screws for quick and secure installation

• Certifications: UL Listed, CSA certified, RoHS and REACH compliant

Benefits

• Safe Grounding: Provides a dedicated grounding terminal set, critical for subpanels where neutral and ground must remain isolated

• Flexible Conductor Use: Supports both copper and aluminum wiring

• Easy Installation: Compact size and included screws make it easy to retrofit or install in new panels

• Space-Saving Design: Minimal footprint allows for installation without disrupting breaker layout

• Code Compliance: Meets key safety and environmental standards for modern electrical systems

Typical Applications

• Subpanels in residential or commercial buildings

• Load centers requiring additional ground terminations

• Electrical upgrades where code requires separation of ground and neutral

• Projects involving copper or aluminum conductors

Installation Tip

When installing in a subpanel, always confirm whether the panel sticker or manual specifies the PK7GTA as the required ground bar. This ensures UL compliance and proper grounding practices. The bar is typically installed vertically along either side of the load center, depending on available space.
