I thought that there was a new rule in 230 that we need a disconnect at the pedistal and 4 wire to the panel.hmy:

The pedistal 30' from the home to the the MDC inside the home in the basement where the cable comes through the concrete :roll:What pedestal to which panel in what place?

It's serving two homes. From transformer to meter out to houses.
Is it just trailers that need a disco before going back underground and entering :?
For your situation I think you can run triplex above or below to the house and install the Service Equipment there.
With that being said, if the pedestal at the Transformer is actually a Meter/Main with overcurrent protection, then there will be different opinions of whether or not a 3 wire or 4 wire installation to the house would be required.
Some will say that run from the pedestal to the house is still Service Conductors since the power company may retain the right to change it out to a Meter Only in the future.
Some will say that the run from the Meter/Main to the house is a feeder and thus requires a 4 wire installation.
If there is only a meter at the pedestal by the transformer, then, I'm in the 3 wire installation to the house group,
but,
If there is a Combo Meter/Main a the pedestal by the transformer, then, I'm in the 4 wire installation to the house group.

Not even a remote chance of debate. The conductors are what they are until the equipment changes, not because the equipment might change in the future.There is debate about this??? :happyno:

Go ask K-wired about this subject and let me know how it turns out.

So, if the disconnect is removed or may be removed in the future......

yes, 550.10 describes feeders for anything with wheels

The Code is prescriptive, not anticipatory. It is quite clear that a single phase service can have 3 service conductors up to the service disconnect. Then a GES must be installed, and an EGC must be used from the service equipment to all downstream equipment. If a service disconnect is at the pedestal, 4-wire runs from there to the house. If the utility decides to remove that service disconnect, then the EGC can be a bond, or could be abandoned. This depends upon local code and/or utility requirements for a GES or bonding at the meter base. NEC only cares about grounding from the point of the Service Equipment and on from there.
Here a POCO owned/maintained/installed disconnect (pole/pedestal doesn't really matter) is not considered to be the service disconnecting means by AHJ. Reason is POCO can change it to non fused during a repair, upgrade, etc. Been times I have had to put my own service disconnect right next to POCO supplied equipment that otherwise would have been sufficient to call the service disconnect. If on a building instead of a pole or pedestal, it doesn't get asked who owns it nearly as often though and might be able to work things to your liking regardless of who does own it, but usually equipment on a building is owner's equipment and not POCO's.And that's where there's been more than one discussion on this forum before as to where that actually is when it comes to Power Company owned pedestal or a Customer owned pedestal.

I've ran into it also.
It's not as cut and dried as everyone might think at times.
