I believe this is likely a POCO item, but are there any clearance minimums from a service drop to a home (especially a wall air conditioner)?

Please see 90.2(B)(5)a, the NEC will not apply, that will be NESC rules. (This assumes the service point is at the weather-head as is normal in many areas.)


90.2 Scope.

(B) Not Covered. This Code does not cover the following:

(5) Installations under the exclusive control of an electric
utility where such installations

a. Consist of service drops or service laterals, and associated
metering, or

From NESC 234C3(c): "Wires or cables attached to and run alongside the installation shall have clearances from the surface of the installation not less than 75mm (3 in.)"

FYI: 10 ft. over decks and balconies, 3 ft in any direction from windows, doors, porches, decks, fire escapes or similar locations with two exceptions, service drops above top level of a window, or windows not designed to open.
 
I believe it's more of the case where something was first! Other trades have a dead front rule to go by, but not that it mattered when there ready to put in the unit.
 
Our POCO would not allow it to be that close to the AC wall unit, not that in its self is a danger, but add a little wind like we have had today and you have a drop rubbing against the AC unit, when it rubs through its all over, imagine the available fault current in that drop being imposed on the EGC of the circuit feeding that AC unit, that would not be an if it will happen but when.

I believe the riser pipe should have been raised to prevent this.

Might meet code but does not meet common sense.:happysad:

Are NESC codes available for free legal online viewing like NFPA?

Not that I am aware of. I have been looking for a few years now. A searchable pdf. version would be great, but it must be purchased. I have the last 6-8 cycles now in book form because they are a requirement on the job (new editions, too cheap to throw the old ones out) and the company pays for them.
