Are these splices acceptable.

Thanks
Mat

I am assuming that you are asking about the blue twist-on connectors at the top of the panel. As long as the wire sizes are within the listed range of the connector they are fine.

Looks like it needs a grounding conductor, a grounding bar and the grounds and neutrals should be seperated and the bonding screw should be removed. Assuming that there is a service disconnect up stream.

It does not really matter, nothing else in there is correct.

It was a DIY but I was just curious about the splice.

Mat,

This is why I say that does not matter: That is not "service equipment" yet the feeder (what used to be service entrance conductor) does not contain an insulated neutral and a separate ground. That means the feeder conductor needs to be replaced anyway.

Now, if that IS supposed to be the service equipment, then it needs to have a main installed in it and it is likely not designed for a main with the main lugs present.

Finally, being old service entrance cable with the uninsulated neutral/ground conductor looking like aluminum, that is not allowed to be spliced to the copper (what looks like copper) conductor in the wire nut with that uninsulated neutral/ground from the old service entrance cable.

Thus my comment that it is all wrong too.

Yes, wire nuts may be used in the panel enclosure, but ONLY if the conductors they are being used on do not pass through the enclosure (that one does not) and they do terminate in the enclosure (that one does) and they meet all other applicable requirements (that one does not).

Thanks Jerry. I identified most but not all of it. Thank.

Mat,

I didn't identify all of the issues either - all I did was point out the tip of the iceberg and warn you that it was an iceberg (what is it they say about icebergs ... something about 7/8 of it is underwater and is not seen ...

).

I think that is 2/3 but who is measuring ?

Some people do measure things like that: How Much of an Iceberg Lurks under Water?

I'd always heard 7/8 was below water, learned that a very long time ago in school, have no idea what grade it was, though.
