The Type SE grounded service entrance conductor, grounding electrode conductor and all of the equipment grounding conductors are secured to this split bolt.

The MBJ is also installed as required.

The home is still being built in the Albany, NY area and this equipment was not inspected yet?

Do you think that the AHJ will accept this concept?

The work was done by an electrician

With the exception of the EGCs, this would seem to be "ugly but legal", as far as I can see. The split bolt does appear to be the required Cu/Al type, but AFAIK, split bolts are only rated for 2 conductors.

If the EGCs are moved to the neutral/ground bar where they belong, then it might have a chance of passing.

Was there no large hole available on the neutral bar to take the GEC? And it looks like the installer used his teeth to strip the GEC, as well...

Too rough looking, but might pass.

I think the gutter for the Romex was a good concept, but question the huge wad of wire passing thru the chase nipple (if there is one). Not as far as derating, but just to trace/locate a circuit or its breaker.

And notice all the tripped breakers? Lots of red showing!

(edited for spelling)

No matter how you look at it, this is a "Sub Panel" and needs to have a Ground Bus insatlled. The MBJ will be at the Main where it belongs.

I don't see why this is a sub-panel. Anyway, I see it as a violation of 250.64(C) Continuous.

Will the AHJ pass this? Who knows they very well might, there are many inspected services that use a split bolt connector in this manner.

I think the question is Should they pass this?

IMO no, the AHJ should not pass this.

Now this does not appear to me to be a sub panel.

I also do not see this as a violation of 250.64(C).

The GEC may be connected anywhere from the weatherhead to the panel.

 Quote:
250.24(A)(1)General.The connection shall be made at any accessible point from the load end of the service drop or service lateral to and including the terminal or bus to which the grounded service conductor is connected at the service disconnecting means.


What I do see is a 110.3(B) issue as NJwirenut was pointing out.

That split bolt connector is only listed for two conductors not a 'dozen or so'

That 'green' is not insulation, it is green tape covering all the individual EGCs for the branch circuits.

My bet is Joe is also looking for 408.20.

 Quote:
...Where the panelboard is used with nonmetallic raceway or cable or where separate grounding conductors are provided, a terminal bar for the grounding conductors shall be secured inside the cabinet.....

408.20 ... Bingo!

Also, this was the main service panel, see the MBJ "Green Screw" upper right.

MX...I hope the breakers are "tripped." That's how they come from the factory. (As a quality control measure, the breakers pass through a magnetic field that trips a good breaker. Those that don't trip are trashed. This is done as one of the last steps before packaging.)

renosteinke:

Thanks for the info!! I had always wondered why they arrived tripped from the factory. I had thought it meant they were mishandled in shipping...
