hi.
one of the electrition in our company tried to wire a three phase pool air blower {in star connection}.
when he connected the three phases to the air blower after one minute the air blower coils were burned.
the thing is before that there was another of one phase air blower and it was workung fine.
the three phases that goes from the panel are 1.5{mm^2}.
so the man connected each one of them to the three terminal at the air blower(to W1, U1, V1}
after a minute the coils were burned in the air blower.
i'm kind of new in that business so i trying to think what is the problem to learn more.
the three phases goes through a circuit breaker to contractor and then to the air blower.
maybe we need to put three phase circuit breaker?
in the picture you can see the burned cables.
the power of this air blower is 2200 watts and the three phases giving together 380 volts.
that means that the current that goes in the three phases is (2200\380= 5.8A}?
and by that i need to choose the circuit breaker?
thanks.
