Hi, the home inspector gave this a pass..

But I am trying to learn, there is one multi wire branch circuit which is in the kitchen for the dishwasher and "instant hot" water dispenser. They share the receptacle (top and bottom) and the breaker has a tie in it. In this picture you see it on the right column, level 2 and 3. Tied. I understand this one.

What I don't understand is why there are other red wires.. which is usually used for multi wire branch circuit, but the breakers are not tied nor is the location close together. namely right column 4th from top, left column 4th from top.

Do you know the reason where red wires are used. I think these are NM cables. Do they have NM that have red + black and 2 neutrals for return??

Reds are just a second hot conductor. They just need to be on opposite legs of the panel from the black in the same cable to avoid overloading the neutral.

Newer codes require the common disconnect of a 2 pole breaker or handle tied breakers unless the black and red landed on the same device.

Do you see the clear jacket wire connecting neutral and ground bus bar,
Is this allowed ?
This is the only sub panel after the 100amp service disconnect , the report says the ground cannot be seen where the 100 amp box is. I am pretty sure that is grounded in some way to the meter or something

So then the ground and neutral wires can go into any of the terminals on either bus bar?

Neutrals cannot be on the ground bar in a subpanel.

Ok I think the picture is hard to tell, it could be tying two ground bars together, looks like neutrals are further out.

Ground wires should go only to the ground bar,
Neutral wires should only go to tne neutral bar.
The wire between the two is called the "BOND".
There should be only one of these, in the main panel.
if it is a sub panel there should not be one !

yes they do make nm with red+black and two neutrals.genarly comes in 12 or 14 gauge.it is called 12 2 2 or 14 2 2.the neutral with the red stripe goes to red wire and plain white goes with the black.
