That is a joiner so you can use the bars either side for neutral connections. It is not intended to be removed. You need to add an additional bar for your grounds using some of the holes in the lower left of the bottom picture.
Ok that makes sense. So i'll connect the joiner and use both those bars for neutral only.That is a joiner so you can use the bars either side for neutral connections.

Exactly, and that's why I tried to give as comprehensive picture as possible of how the use of the panel (Service Equipment vs Equipment) will determine how the buses are configured.Both of those bars appear to be mounted on isulating brackets which would make them a neutral bar. The bond strap is not installed. You can see it near the bottom bus to the left in the pic.
Hi Craig,Exactly, and that's why I tried to give as comprehensive picture as possible of how the use of the panel (Service Equipment vs Equipment) will determine how the buses are configured.
If the panel isn't going to be jammed with twins/tandems there are sufficient slots on each bus to accomodate all neutrals on one, and (if bonded) all grounds on the other, without necessitating the purchase of added grounding buses.
If non-CTL breakers (twins/tandems) are used (I see the notched slots at the bottom) and the panel is filled or otherwise winds up with more than twelve neutrals, then added grounding buses must be used.
If I understand you correctly; I can remove the black bar from both bars and use one of the bars for neutral whites and the other for bare grounds. For the bare ground I will need to rotate that little hook with the green screw on it into one of the slots on the proposed ground bar as illustrated below?Not totally so. The bonding jumper is intended to be installed if the panel is used with a main breaker as service equipment (a "main" panel), where neutral (grounded) and ground (grounding) conductors are bonded. The neutral and ground wires may be connected to either bus, but typically for appearance and clarity you can use grounds on one and neutral on the other. There should be a bonding screw or tab connecting the buses to the panel case.
When used as equipment (a subpanel), the neutral bond to the panel case can be removed (typically a screw or tab from one bus into the case back). The bonding jumper in question must be removed so no connection exists between the neutral bus and the ground bus, allowing the neutral bus to "float" (not be connected to ground). This alows you to use one bus as neutral, the other as ground. The ground bus should still be bonded to the panel case.
Thanks I'll do my best to remove the stripped screw...it is crazy how easily it strippedRegarding the stripped screws, remove the screws on either side and use vise grip to remove them. Or get a set of stripped screw extractors and use one to back them out. Or return to panel to the big box and exchange it for one that isn't farked.
Twins or tandems come in CTL and non-CTL versions. The slots are there for the CTL versions.If non-CTL breakers (twins/tandems) are used (I see the notched slots at the bottom)
Some CTL load centers allow a limited number of non-CTL breakers. The OP's is one of them. It's a Cutler-Hammer BR. It is labeled CTL. It has two non-CTL blades visible in the pics (the unused slots) and so will allow installation of at least four non-CTL breakers.Twins or tandems come in CTL and non-CTL versions. The slots are there for the CTL versions.
Non-CTL's are for replacement use in panels built before 1967 (IIRC), and they are not to be used in CTL panels.
Putting non-CTL breakers in that panel would be a code violation.
Interesting...what is the neutral provision on the terminal bar on the right side?The terminal bar on the right hand side of your panel will be your neutral bar. It has the neutral provison .. the other bar does not. The bonding jumper should be installed to the bar on the left hand side of the panel.
Then interchange your whites and bare grounds.
Well you are missing the conduit that the feeders should be run in. Also the green to the neutral bus is the wrong color.
Am I going to fail inspection because of the green instead of white? Lowes didn't have the white so I figured green would suffice. Also I have to get the metal conduit still so I didn't hook up to the main panelOk I finshed the wiring within the sub panel. I didn't hook up to the main panel yet and plan to run metal conduit for 5" into the main panel above the sub panel...really is a sub panel
Lowes didn't have white 6gauge THHN![]()
