Ground Bar Kit for QO Load Centres
The Square D PK3GTA1 ground bar kit provides a dedicated grounding point inside compatible QO load centres. It is rated for 70 A and accepts aluminium conductors from 12 AWG to 4 AWG and copper conductors from 14 AWG to 4 AWG. Two mounting screws are included for secure installation. The aluminium construction ensures reliable conductivity for residential and light commercial panels.
Installers fitting Square D QO panels
Electricians wiring new or replacement QO load centres will find the three terminals suited to typical branch-circuit grounding needs. The kit is not intended for panels outside the QO range or for applications requiring more than three grounding connections. Buyers needing a higher terminal count or a different mounting pattern should select an alternative ground bar.
70 A rating with three terminals
The decisive specification is the 70 A ampere rating combined with exactly three terminals. This defines the maximum current the bar can carry and the number of grounding conductors it can accept. Verify that the load centre specification matches both values before purchasing.
