In this area there are two types of electric fencing installed. One is the "standard" "farm" type with a 120v fence charger sending pulse charges along the fence wire, the second is a "dog" fence, battety with solar panel sending a 7000v miliamp pulse charge. I have been asked if either of these would under the scope of the NEC?
90.2 does not seem to calrify. Opinios please.
 
not that it changes anything, but the 12v/solar doesn't plug in.

90.2(A), the NEC applies to electrical equipment installed at premises [90.2(A)(1)] and yards [90.(A)(2)]

OK, so it is within the scope of the NEC. But the NEC usually doesn't give much guidance to the installation of appliances (other than some specific cases).

I would assume the installation of the controller and the fence would be covered under the UL listing of the fence controller under 110.3(b).

And it not a design guide, its an installation guide.

Depends on how good their guide is. I'm sure it's pretty good.
Just to think of the product liability issue's. Etc.
I'm sure thier listed and could never think the subject matter wasn't coverage by the code.
Not that it wasn't or couldn't be, I just had to wait for others to answer. Keyword(s) Premise Wiring.
Thanks all ...
 
Both of these electric fences can have transformers that are "plugged" in to receptacles, just like most LV landscape lighting. I would call them appliances/end use equipment not premises wiring. The Wisconsin state code does have a minor section on "cattle" fences, and requires the supply transformer to be listed.

True that, I'll go with you in thought, and I can only hope that all services are correctly addressed.
