Installed a 200A non SE ATS directly adjacent to a 200A MCB panel as part of a standby system. The feeders coming into the house are from a meter pedestal with a 200A OPCD at the pedestal.

Inspector is stating that this OCPD does not count as it is utility property.

Agree or disagree?

Also 230.91 states the OCPD can be directly adjacent to the disconnecting means. Would the transfer switch fit this description?

Thanks!
 
Regardless of "ownership" of the pedestal breaker, it would seem to me the non-service ATS would be a violation of 225.31, 32.

If there is an OCPD at the pedestal as stated by OP, I'm not seeing how The ATS next to the panel violates 225.31, 32.

Would you help me understand?
 
225.31,32 require a disconnecting means at the building itself and 225.36 requires that disconnect be suitable as service equipment.

Only if you are on the 2011 or earlier code. The requirement for the second structure disconnect to be service rated when away in the 2014 code.

Forgot that.. but it is doubtful a non service ATS would meet the remaining requirements in 225.52.
Agree ?

Is the pedestal POCO owned/controlled?

We run into similar around here on many rural services - POCO's typically install a disconnecting means on a pole on rural services usually 200 amp and less, but does vary to some extent. Some will have overcurrent protection some may not.

General rule here is that disconnect is provided and maintained by the POCO is not considered the service equipment even if it contains overcurrent devices - the reasoning is if controlled by POCO it could be changed to something that doesn't have overcurrent protection.

There are advantages and disadvantages to this local rule.

Advantage - if you have a long run to a building - only needs to be three wire and is considered service conductors.

Disadvantage - If supplying a mobile home and is right next to the mobile home - you still need to install an additional service disconnecting means between it and the mobile home.

There is likely others - but this is some of what I have come across.

I can see OP's ATS being an issue on some of those installs.

The disconnecting means is SE rated and is directly adjacent to the transfer switch per 230.91.
It is not a modular. The wires come from underground directly into the transfer nippled to the MCB panel.
This help anything?
