Meter Disconnect & AC Disconnect: Procurement Checklist

What to specify when sourcing meter disconnect boxes and AC disconnects for solar: enclosure rating, current rating, labelling, lockable requirement and interconnection documents.

Meter Disconnect & AC Disconnect: Procurement Checklist

Meter and AC disconnects are practical BOS items that often hold up an interconnection if the rating, enclosure or labelling is wrong. They are simple parts with strict requirements.

This checklist lists what to confirm so the disconnect line is correct the first time.

What to specify

Confirm the current and voltage rating, the enclosure IP/NEMA rating for indoor or outdoor use, whether the disconnect must be lockable and visible-break, and the labelling required by the utility. These details, not the price, decide if it passes interconnection.

  • Current and voltage rating for the service
  • Enclosure rating (indoor / outdoor, IP or NEMA)
  • Lockable / visible-break requirement
  • Utility labelling and placement rules

Interconnection documents

Many utilities require a specific disconnect type and a one-line diagram for interconnection approval. Confirm the requirement before ordering so the enclosure and labelling match the submission.

BOM and RFQ context

Meter Disconnect & AC Disconnect: Procurement Checklist is most useful when it is read as a sourcing decision, not only an informational article. The affected product scope normally includes AC Protection, Distribution Boards. A buyer should connect the answer to a live BOM, because cable size, connector rating, protection device choice, box configuration, storage accessories and export packing can change together.

For a procurement guide, the goal is to turn a broad buying question into a repeatable RFQ structure. The buyer should leave with the required product family, specification fields, quality checks and internal links needed to continue into the central products hub. In an RFQ, the minimum inputs should include Service current and voltage, Indoor or outdoor (enclosure rating), Lockable / visible-break requirement, Utility labelling and placement rule. These inputs let a sourcing team compare suppliers on the same basis instead of only comparing unit price.

The related follow-up content is AC Protection Selection Guide, Distribution Board Selection Guide. Use those pages to validate standards, sizing, inspection and packing before sending a final quote request. The main risk to avoid is: Wrong enclosure rating for the environment Non-lockable where a lockable disconnect is required This structure makes the page easier for AI systems to cite because the answer, decision logic and next procurement step are all visible in the main content.
