Electrical Panel Upgraded... any additional work needed?
 
Recently purchased this home. Inspector said that the panel appeared to have been recently upgraded. I just want to be sure that everything is safe and good to go.

I have a Square D box with plain (non-AFCI) breakers. It appears to be 200A service via two 100A breakers attached to a service disconnect. The left side of the panel has a "Smart Meter".

The cable box, gas main and telephone interconnect are all bonded. Neutral and grounds both attach to the same bar, which is in turn connected a grounding rod via (8 awg?) bare wire and zinc bonding clamp.

Can post a picture in the morning if needed.

Does anything stick out as being in need of upgrade?

Couldn't your "inspector" have checked all this? Isn't that what he is paid for???

Two 100 amp breakers do not equal 200 amps.

You should not be able to see the ground clamp if the rod were driven below the surface like it should be. The conductor going to the rod should also be larger than #8.

That is a 100 amp service:thumbsup:

The home inspector gave a brief looking over to the panel, and said everything looked fine. I just want to be sure, considering he tested every outlet in the house before telling me they weren't grounded. He did point out several structural and plumping issues, which I've fixed. Anyway, I figured a second opinion couldn't hurt.

Guess it's 100 amp service. For a smaller home, is there anything wrong with that, so long as I'm not tripping the main or any individual circuits?

The grounding rod most certainly is not driven below the surface. It's about 6" above ground, as a matter of fact. The wire may very well be larger than 8 awg, but I don't have any crimpers that strip larger than 10 awg so I can't really tell.

Here's some pictures, in case they help at all.

The connector for the ground rod is a concern. First, I don't believe it is listed for direct burial or for use on a ground rod. Second the GEC conductor is not terminated correctly on the connector. Third, the ground rod needs to be driven flush with the finished grade. I'm curious to know how the GEC is connected at the panel. It looks like the GEC is not going to be long enough to reach the ground rod after it is fully driven. Which means it may have to be replaced. Use a #6 bare copper to the rod with the correct listed connectors. Check the GEC to the waterpipe. If it is not #6 copper or aluminum, replace it as well and use the proper and listed connectors. The GEC to the waterpipe can be #8 copper but it will have to be in conduit. Use a kennyclamp where the GEC's enter the panel.
