| 1. Standards and design verification | Can explain which standards apply to the empty enclosure and which apply to the completed electrical assembly. | Request current test reports and declarations relevant to the product. IEC 62208 covers empty enclosures for low-voltage switchgear and controlgear assemblies; IEC 61439-1 provides general rules for low-voltage switchgear and controlgear assemblies. | Confirm the report covers the offered model, material, dimensions, and configuration. |
| 2. Ingress protection | Offers an IP rating suited to the installation environment, with sealing details for doors, cable entries, and mounting interfaces. | Ask for an IP test report referencing IEC 60529. The required rating depends on exposure to dust, water, and the local installation rules; an IP rating alone does not establish suitability for every outdoor site. | Check that the tested configuration matches the proposed cable glands, locks, and accessories. |
| 3. Impact and mechanical protection | Can state the enclosure’s impact-protection rating and describe how the door, hinges, lock, and body are tested. | Where an IK rating is specified, request test evidence referencing IEC 62262. Select the required level based on the site risk and applicable project specification. | Verify the rating applies to the complete enclosure, not just a material sample. |
| 4. Outdoor material and UV suitability | Provides material specifications and evidence that the selected material and finish are suitable for the intended outdoor conditions. | Request resin or metal specifications, coating details where applicable, and relevant weathering or UV test data. Suitability depends on climate, exposure, and the product’s construction. | Check material grade, corrosion protection, temperature range, and maintenance requirements against the project conditions. |
| 5. Meter and utility compatibility | Can confirm internal clearances, mounting arrangements, cable access, and any local utility requirements before production. | Request dimensioned drawings, mounting templates, and a compatibility checklist based on the meter model and the utility’s installation specification. | Obtain written approval of the final drawing before placing a production order. |
| 6. Customization and production control | Has a defined process for custom dimensions, cut-outs, inserts, locks, colors, and revisions, with repeatable quality checks. | Ask for a controlled drawing revision, sample approval process, inspection plan, and records for key dimensions and materials. | Clarify tooling ownership, change-control steps, minimum order quantities, and sample lead time in writing. |
| 7. Export readiness and supply reliability | Can document packaging, shipment terms, production lead time, inspection arrangements, and after-sales support for the destination market. | Request a written quotation with Incoterms® 2020 delivery terms, packing details, stated lead time, warranty terms, and a pre-shipment inspection option. | Check destination-country compliance, shipping responsibilities, spare-parts availability, and the process for handling defects. |
