Can you spot the problem?

[KEVIN WOOD]

Sorry guys!

I was out of town. Robert wins this one.
The mains are 60 Amps but there are two apartments with two stoves and two hot water tanks. They cannot have a dryer because the service is too small.
The three wires serve the grounds and neutrals to two units. The disconnects are for two apartments that makes it have service of 60 amps/apt. A stove needs 40 Amps.
The tell tale sign is the two grounds on one lug in 60 Amp panel.
Panel is only rated for 100 Amps this puts the panel at 20Amps over
Water was only warm and the element was broken on one oven.
I wonder why?

Sounds like a mess. But Im not really following what ya mean by the 100A panel is 20A over.

Panel is only rated for 100 Amps. The panel is down stream from two 60 Amp main disconnects.

That matters not the service is a 60 amp service .
It just says the panel can be used as part of a 100 amp service .
It goes back to the weakest link .

It is also cheaper now to buy a 100 amp panel then a 60 panel and it has room for more breakers .
Example
Just because some one puts in 2 inch conduit and a 200 amp panel it has wires for 150 amp and a 150 amp breaker it is a 150 amp service .

It is not 60 Amps it is over 100 Amps I could not determine the size. There are two meters outside and a mess of ungrounded and reverse wiring.

There can only be one service disconnect (main).

Pictures?

[KEVIN WOOD]

I only provided the one for education purposes.
Here is the other one.
I could not put my camera on Macro so this picture did not turn out well.

Is the feed from the top in conduit?

[KEVIN WOOD]

Yes it is

[Robert J. OConnor]

There likely is another breaker/fuse distribution panel somewhere. I have seen them in strange locations (e.g. behind a mirror in a 2nd floor bathroom, inside kitchen cabinets, behind pictures, etc). With two meters you would have the two main fused service disconnects (one for each meter/service), with each one of those likely feeding a separate distribution panel.

Probably a panel for each apartment. One would have a black-black-white (H-H-N) feeder from one of the 60A fused disconnects to a distribution panel, and the other one would have a black-red-white (H-H-N) feeder from the other 60A fused disconnect to another distribution panel. The conduit is likely the ground to the distribution panel. What were the number and color of the wires going to the 100A panel you did find?

Also in the fused service disconnect boxes it looks like 3-wire feeders (H-H-N) come in from the meters and go out to distribution panels in conduit, then there is a white wire used for the earth ground (GEC), and two brown wires used for the neutral-case/ground bond.

I found one fuse panel in the upstairs apt.
I found two conduits going to one possible 100 Amp service. It cannot be two hundred amp because of the 100 Amp panel.
I am still stumped how this could have been wired.
I did not pay attention to anymore detail after I found the double wire situation in the neutral lugs.
I told my client to seek advice from certified electrician.
They are going to correct it by installing 200 Amp service and panel.
