Does Anything Look Odd with this Service?

[Pierre C Belarge]

This is the supply from outside to the inside of the building, a large service.

Does anything look odd?

 

[ibew501ed]

do you mean the 1 white wire on the neutral bus that's not run with the phase conductors?

Missing a few noodles?

 

[Ragin Cajun]

Sure wouldn't have to "fix" this one. Lots of conductors. Wonder what the drawings showed.

wouldn't want to tell my boss we forgot a few wires.

Im just a resi guy, but that sure doesnt look right.

Not really sure, but the phase markings above the terminals apprear to be N-3-2-1. Reverse rotation?

Also, there's some 'spare parts' in the far end of the cabinet.

Was a nutral needed ? Can see nuetral and 1 conductor going some place. Perhaps a small single phase load

 

[whillis]

I'm with Jim. It could be that the majority of the loads do not require a neutral so a derating was applied. If this is the case I sure hope the building isn't re-purposed without someone looking at the service!

Without knowing the service requirements it is not possible to pass judgment on the single 'grey' conductor. If this is a high impedance grounded system, the single grounded conductor is allowed to be run separately from the phase conductors.

with the extra neutral in one conduit,this does not meet paralleling criteria.

look again it does not go with the others

follow the conductor it goes down conduit at rear right

 

[nakulak]

I guess its possible that could be the neutral, but where's the main bonding jumper ?

 

[benaround]

Looks like they brought the GEC's to the wrong section, had to sneak them under the

bottom bracing.

yes back row with 1 brown and 1 orange

We need better pictures Pierre

 

[peter d]

What we need is more wild speculation.

So, I'm speculating that this is a delta service.

 

[mcelweec@gmail.com]

the yellow is there too,extremely hard to see.

 

[benaround]

I think Jim Dungar answered that on post #10.

 

[nakulak]

ok, if that is the neutral, and its not high impedance, and I am counting 9 other conductors, then the neutral does not meet the 12.5% rule.
