patulong naman mga expert mag wa wiring kc ako ng 6 na (welding machine 350 amp) 60 amperes po ang breaker bawat 1 welding machine yung main breaker naman 300 amperes tanong ko lang kung kakayanin ba ng (wire 50mm2) ang 6 na weld machine di po ba lalagnatin yung mga wire pag nag sabay full weld yung anim na weldingan
share ko lang brod...
SIZE OF CONDUCTOR:
Ifeeder = Ieffective* <---conductor size.
*from the nameplate of the welding unit.
Ifeeder = Imax* x duty cycle <---if Ieffective is not given.
*actual testing
OVERCURRENT PROTECTION:
Iop=Ieffective x 200%
FEEDER SIZE FOR A GROUP OF WELDERS:
Ifeeder=summation of two largest welding machines*100% + 80%*Ieffective of 3rd largest welder + 70%*Ieffective of 4th largest welders + 60%*Ieffective of all the other welders.
