Plans & docs
- Site Plan Reqs
Standard - Must show distance between AC Disconnect and utility meter, if equipment is not grouped together. If grouped together a note stating equipment within 10' is adequate.
AC Disconnect Required
- External, visible and lockable disconnect within 10 feet of the utility meter
- If the AC Disconnect is not within 10 feet of the utility meter, the utility must approve the location prior to installation, which may require a utility site visit.
- If seeking a variance from the 10 foot requirement, the installer must show the proposed location of the AC disconnect in the detailed site diagram, and include an explanation justifying the need to locate the AC disconnect more than 10 feet from the meter (including physical limitations).
- SLD Reqs
Standard - Must show distance between AC Disconnect and utility meter
- Electric Service Reqs
- Install Reqs
Northwestern energy will not allow us to install on split structures IF the home has 2 or more meters - If it has 2 or more meters, the panels MUST be on the structure the meter we are offsetting is on. For example, if the home has 2 meters, one of the detached garage one on the main home, and the customer wants the panels on the garage but we are offsetting the main home meter, they will not allow this.
