Help needed!!

[David C. Macy]

Home has a 200 amp service. The panel had 2 100 amp breakers that feed into a sub in the house. House was all electric. Why didnt the just run 1 set of wires?

The garage sub was improperly tapped at the main.

The sub in the house had evidence of overspray from paint & the bonding stap was only connected to the box.

Are there any other problems that I over looked?

The home had a garage that was only attached on 1/2 of the back wall. The wires break thru the firewall in romex only. Shouldnt conduit or BX be used and there be a tight seal? Are you allowed to run romex thru a firewall unprotected?

Thanks

I think there was another panel, or some other type of equipment being fed from the service equipment.

One feed goes to the panel in your 4th & 5th picture. The double tap feeds the panel adjacent to the service equipment and the other feed goes somewhere else. . .

Around here it is allowed as long as the hole is tightly sealed.

Trying to get the hang of the quote icon

It looks like the 2 feeds from the main go to the sub in the house. I believe then the other set of wires are going to the electric furnace. I was expecting to see another sub in the house.

Looks like a double tapped buss in pic #4

Dave,

Ok, I am not all that worried about the spray in the panel, the wire running through the firewall as long as it is sealed .

However, it looks like the SER conductors are running into the main disconnect without any support connectors, also I can see that the one SER that is going to the remote panel listed is (4) conductors.....I question the one on the left....does that also go to the remote panel or a HVAC unit inside or something because that is only SE cable.

While I am going to incline to agree with Jeff on this....BUT I hope it is not being fed by the SE cable....as that would be incorrect for the installation.

Now we could also say the SE and SER are not supported within 12" from the enclosure as well....and with not having any support connectors...I would be concerned about that.

On that remote panel...the bonding strap needs to do as it is doing now...nothing.....but I would have removed it as someone could come along and incorrectly bond it.

I also question the bends to the terminals...but alas......really not something you should go into......defer the issues I have stated and then the electrician will take it from their IF they intend to have anything fixed.

It appears in pic's 4 and 5 that the white neutrals are doubled on the bus - should be one wire to one terminal.

You took some very good pictures, it shows me that you have a pretty good idea of what may be wrong here...which is there is plenty wrong!

What kind of connectors are securing the SER to the enclosure? It looks like chase nipples. As Paul stated how are those cables supported? There is a neutral and an equipment ground conductor under the same terminal. There is double tapping of phase conductors, and improper fusing of those same conductors. The grounding electrode conductor enters the enclosure through the same chase nipple as the SER... multiple violations there. The ground/neutral bar in the main service disconnect does not look as though it is bonded to the enclosure.
There are other violations, but I will let Paul find them

[Paul W. Abernathy]

Go for it Pierre...lol.....I never point them all out, i like when others chime in also.....hoping the original poster will eventually list them or others can get involved....

Plus I am on LOL restriction......can't post but a few posts or my LOL quota is full.

The IRC does not require the wall between a garage and the house (R3) to be a fire rated assembly

[Paul W. Abernathy]

I believe the IRC just says a Min of 1/2" sheetrock on the garage side of walls that are common to the house.
