Where to attach neutral/ground in breaker panel

[JoeXYZ]

Installing an over the range microwave, ran the (yellow) wire to the box, but where can I attach the ground and neutral wires? The one bus on the right is full, the second bus on the right is empty, but can I use it? Nothing else is attached to it.

If that’s is your main panel you can hook up the grounds and neutrals to any one of the bars. If it’s a sub fed panel the neutrals have to be isolated from the grounds

Surely it's all the same piece of metal?

No it’s not, the neutral bar has an insulator on the bottom and is not an integral part of the panel, the ground bar doesn’t have an insulator

 

[Soi disant]

Can't I see ground and neutral conductors connected to the same things?

Yes in the first panel after the power company service and any panel after that the neutrals and grounds must be separated

 

[Soi disant]

Either I'm more confused than I thought, or we're at cross-purposes.

Am I not seeing, where highlighted, ground and neutral conductors connected together?

Let me ask you a question. Is that the only panel you have and is it located outside

 

[Soi disant]

You should ask JoeXYZ, not me ?

 

[Soi disant]

Yes in the first panel after the power company service and any panel after that the neutrals and grounds must be separated

Would this be a 3-pole switch, or only 2P, for the two lives?

It is a 2 pole 240vac. Residential is only 240/120 vac

 

[Soi disant]

So if neutral isn't switched, then whatever the power company think about it, the electrons aren't going to be able to tell the difference between neutral and ground only combined to the point of entry of the service, and them being combined all the way to the distribution board, as in this case.

No it’s not, the neutral bar has an insulator on the bottom and is not an integral part of the panel, the ground bar doesn’t have an insulator

So, in terms of the panel construction, what are A, B, and C, and which have continuity?

You just have A phase and B phase and the neutral that’s in the middle looks burnt. It appears to be loose

It's the only panel, it's inside.
