Copper discharge flow reference table
Query the current carrying capacity based on the copper bar size
This table reproduces public reference data from the original site. The relationship between dimensions, copper thickness, and current rating has not been independently verified.

Conditions of use
- • Ambient temperature: 25°C
- • Ampacity is based on horizontal placement and natural cooling conditions
- • When there are multiple copper strips, the distance between the strips and uneven current distribution need to be considered
- • Actual selection should consider heat dissipation conditions, safety factor and temperature rise requirements
