Suggestion for service wire

[Prophet455]

Building another garage adjacent to the existing garage. The existing garage has a 200 amp service coming from a separate meter pole and box outside. The meter box itself has 4 breaker slots open because it’s main breaker feeds straight to the service entrance wires for the original building. Because the new shop is in the opposite direction of the existing shop from the meter pole, I think it would be advantageous to run from the meter box instead of sub paneling off the main panel in the existing building. Considering running a 125 amp breaker with 2/0 alum cables underground in conduit to the new shop about 100 ft away to its own 125 breaker panel inside. Not sure if this is considered a sub panel or dual service but hopefully you get the idea. Question #1- Is there any code issues so far? Next do I run 3 or 4 wires to the new building-as I understand if this is considered a sub panel I will have to separate ground and neutral but if it’s not- I run a neutral but set a ground rod at the new building. If I have This completely butchered, please help clarify what needs to be done and best options to meet codes/safety.
Thanks

imho, the power company will provide the drop to your masthead.

why 125a? what will you be running in there?

I bet you can get by on 90a and #2 al MHF

yes its considered a subpanel since you have a main disconnect at the meter.

you will need 4-wire and isolated neutral as well as 2 ground rods.

umm who said anything about a new service from the PoCo? he already has service

I agree, think about what you are using, unless you don't care about the cost.

In conduit, you can run individual conductors, which would be xhhw. Another option is MHF (mobile home feeder). Don't buy URD as it (usually) isn't rated to enter a building, so you would have to transition to something like SER.

And just because you're running 125A, or 90A, or whatever to the new subpanel, the subpanel breaker only acts as a disconnect. It doesn't need to match the breaker in the main panel, but should be at least the expected load. No problem running 90A from the main panel into a 200A subpanel for the extra spaces.

My new detached shop garage has a 100 amp main breaker panel I've installed to power the shop. The shop is about 30' from the house meter, which is easily accessible. I'll dig the trench, run the conduit, and cables from the new main breaker to the meter base. Then I plan to hire an electrician to connect the new line to the meter base. That is assuming a new drop can be routed from the meter base to route power to the new detached garage.

Not sure if the meter base must be changed to accommodate a new power drop . I've never done that type of work so I am ignorant at this point. 100 amp service line runs from the street, buried under my driveway for most of the near 100 feet from the power pole to the back of my house. So that won't be changed. Can't do a buried splice where I can find the buried cable where it is routed past the end of the driveway.

Your meter pan needs to have dual lugs. More than likely, it does not

Here are pictures of the meter on the back of my house. I'd like to add another drop off the meter base to my new detached shop 30' from the house. Hopefully I don't have to change the meter base to do that, but I have no idea. Perhaps if I contact Wisconsin Electric they can take a look and tell me what I may need to change.

The POCO doesn't own the meter base and likely have any record onlf what is in there.

They can cut the tag and open the box so that you or a pro can check though
