Why dimensions must be complete
Copper bars are often application-specific. Length and width alone do not define the finished part; thickness, hole pattern, edge condition and connection layout also affect fit.
Core specification fields
Use a dimensioned drawing wherever possible.
Material grade or approved material requirement
Width, thickness and total length
Hole diameter, spacing and quantity
Surface finish or plating requirement
Insulation, marking and packaging
Electrical design remains project-specific
Required cross-section depends on current, temperature rise, enclosure conditions, connection quality and applicable design rules. Do not rely on a generic current-to-size table without engineering review.
Approve the production reference
Confirm drawings or samples before volume production, especially when hole position, bending or insulation affects assembly compatibility.
