Attached structures with 2 lines back to meter?

[chedv]

Current shed has a 3 wire subpanel fed from a 100 amp breaker at the meter/combo box. Bonding screw installed. I do not see a ground bar at this panel.

New shed is attached to the current shed. The meter is actually closer to this new shed, so we plan to run 4 wire to the meter/combo box with another 100 amp breaker. UFER has been embedded in foundation. (If needed)

Is there a problem with attached structures with separate feeds from the meter? Thanks.

If it attached then it's one building. Can't have more than one feed to a building.

If two feeds were used, would this cause a grounding or current issue?

Or is it more of the hazard when working on a circuit, one might not be aware of which panel it’s coming from?

The latter.

Just run a new feed, then convert the existing panel to a sub, fed from the new one.

Gives you a chance to get the existing panel upgraded to a 4 wire also

Where is the meter main located at? On the house or a pole?

Meter is on a pole. Farm location. Main feed through lugs run to the house. Then a 100 amp breaker runs to existing shed.

That’s a good idea. It would be a pretty long run, but doable.

ok so of you run another feed from the meter it wont be code permitted. as previously said you can only have one feed to a structure.

ok so none of that is code permitted. as previously said you can only have one feed to a structure.

What's not permitted about his existing setup?

Two feeds to the same structure

He doesn't have that now, unless I am missing something.

sorry i was mixing up things. correct, existing setup is fine. if he runs the additional feeder as he plans, then it will be a code violation.
