Design and installation review
Provide the busbar section, mounting hole pattern and cabinet attachment details. Show the bar spacing and the complete conductor arrangement around the support. Include mechanical loads, operating temperature and all required insulation and flame performance criteria in the RFQ. Select the PA66 grade and validate the complete electrical assembly against those requirements. Define the seating datums and the fastening method, including any inserts, so the interface can be reviewed before tooling.

Sample approval
Mount first samples on the intended panel and fit representative busbars with the specified hardware. Check seating, fastener access and installed alignment. Inspect for distortion or damage after the agreed assembly trial. Electrical, thermal and mechanical acceptance tests are defined for the completed assembly and its service conditions. Record the material grade, conditioning and mating components used during approval.
Applications and assembly layout
Typical projects include busbar supports for industrial control cabinets and customer electrical distribution assemblies. Pedestal height, mounting footprint and top interface can be adapted to the cabinet drawing. Review neighboring conductors, covers and wiring routes in the assembly layout. Show the installation sequence and access needed for tools. If a support must be replaced during service, include the removal direction and any adjacent components that affect access.
Drawing and first-article records
Send a STEP model and a toleranced 2D drawing of the support with the busbar and panel interfaces. Identify the functional surfaces, mounting datums and documented material requirements. Include planned quantity, color and expected operating conditions. Agree on dimensional inspection and assembly trials before approving production. Keep the approved reference support with its material and test records. Review a proposed change to bar size, mounting hardware or service conditions against the original acceptance criteria.
