This condition can be caused by a charger problem,
a "weak" fuse or circuit breaker protecting the circuit,
or an overloaded circuit.  If the building AC power
fuse or circuit breaker blows, connect the charger to
other outlets (on different circuits) in the building.  If

the charger operates properly on other circuits, have
a qualified electrician inspect and test the original
circuit.  If the charger causes other fuses or circuit
breakers (in the building) to blow, the charger should
be tested for a problem.
