Questions and Answers for Square D QO 100 Amp 8-Space 16-Circuit Indoor Surface Mount Main Lug Load Center with Cover, Door

A:  The QO816L100DS uses #8-1 wire. Regards, Customer Care

A:  I used a PK9GTACP grounding bar for this box. It looks like the PK15GTA but is shorter with fewer connections. There is plenty of space around it, so it seems like thenPK15GTA should work. See below the breakers in the picture of my installation.

A:  The panel specs will tell you what bars they recommend . Use the Square D bars, they fit better. The worst that will happen if using a larger bar then recommended is it will not fit the mounting holes and you have to drill one hole for the mounting screw. I usually drill the hole in the bar and use the original holes in the panel.

A:  The recommended ground bar for this load center is PK7GTA. The PK15GTA will fit this load center. Regards, Customer Care

A:  Yes, main feeders can enter from the bottom. That is the way I installed mine.

A:  Yes. They will still need to be connected at the top. See the example picture.

A:  Yes put feeder wires have to be routed a round to top takes up room in panel but there is room.

A:  The Main Lugs of this load center are positioned at the top of the load center. The interior cannot be rotated to position the Main Lugs at the bottom of the load center. However, there is adequate gutter space to feed the incoming conductors into the bottom endwall of the enclosure, routing them through the side gutter for terminating into the Main Lugs located at the top of the load center.

A:  You should not need a ground bar that big in this panel, you have 8 circuits, when it says 16 circuit you would have to use the piggy back breakers. The 15 space gnd, should fit. Sounds like you need a bigger panel all together.

A:  Hello, A PK23GTACP will not work on a QO816L100DS. It uses a PK7GTA. Regards, Customer Care Center

A:  I used PK9GTACP but there are longer bars like PK12GTACP and PK23GTACP which have more connections. Some bars do not have the "CP" at the end of the identifier.

A:  it is a ground bar that bolts directly to panel case. NOTHING specific a ground bar is just that a ground bar. You get one that is adequate for the panel size.

A:  Hello Don, If you are using the QO816L100DS as a sub panel which is very common, then YES the grounds and branch neutrals must remain separated and they would need a separate ground bar to field install in the panel. For this panel the ground is a PK7GTA. Regards, Customer Care Center

A:  It would Depend on the load you are adding , this is only 100 amps available to start with. If it doesn't overload panel you are good to go.

A:  The maximum number of tandem breakers allowed in the QO816L100DS is 8. Hope this helps. Schneider Electric Customer Care

A:  You to not put the bonding screw in that makes the neutral bar connected to the ground.

A:  Ground and Neutral are not bonded when the panel is new-in-box. You have to bond them with the screw. If you don't, they're already separate.

A:  Thank you for your inquiry. The QO816L100DS load center does not come bonded. We ship the green bonding screw separate that you would install if required.
