we just need to check the permissible cross-section for each one, before getting the copper cables. in the below link on pages 3/11 and 1/12, there is tables "Recommended cross-section of cables". which data is for the two breakers below? breaker 1 :3VT3763-2AA36-0AA0+3VT9331-6AB00 breaker 2 :3VT1712-2DA36-0AA0 |
