Electrical Diagram
  • The Nema 3R disconnect switch should be adjacent to the electric meter and accessible to the servicing utility company.
  • The switch must be fusible, minimum size 100 Amp, single phase or three phase and rated for service voltage.
  • The switch must be securely fastened to the building structure, have a visible open gap between the switch contacts, knife-blade type.
  • Fusible safety switch must include a label staô€†źng voltage and amperage of solar system and all addiô€†źonal labels required.
Label Page
  • Plaques must be either attached to the AC Generation Safety Disconnect or located next to the disconnect. Plaques are not allowed to be mechanically attached to the safety switch with screws, pop rivets, or similar means, as this would compromise the UL rating.
  • Plaque must be a minimum of 5” x 7” in size.
  • Wording for the plaque at the safety disconnect switch must state: “CAUTION: Multiple Sources of Power - Lockable AC Generation Source Disconnect.”
  • If the disconnect is within 10 feet and within sight of the meter, the signage must state: “CAUTION: Multiple Sources of Power - Lockable AC Generation Source Disconnect available for Isolation from Utility.”
  • Plaque must be a two-ply or three-ply, non-conductive plastic engraved plate that is weatherproof and UV resistant.
  • All solar raceways/conduit installed with DC and AC conductors must be labeled every 10 feet minimum as:
  • “Warning: Photovoltaic Power Source.”
