Do you think it is good idea for 4 pole MCCB to be used in parallel condutor, wich conductor amperage is 2x each pole of MCCB and use two pole in parallel for each conductor ?, do you think is there a problem ?, example : use 4p 50a MCCB, for single phase 100a load, with 4 core wire (each core ampacity by local code is 50a maximum), and then use two pole in parallel for MCCB ?
By local code, is allowed to use parallel conductor, but each wire needs to be same sectional area, and same type, also same raceway/conduit (if applicable), and each wire needs to be protected by circuit breaker sized for each wire maximum ampacity, example : use 2 wire with 50a capacity for 100a is allowed, but each wire needs to be protected by 50a circuit breaker
