I am not discussing amperage in this video.
When installing or repairing a 250v pool pump
switch make sure you install the correct type of
switch.
This video shows how some one used a stack switch
to control the pool motor.
The problem with the stack switch is that it only
shuts off one side of the power supply to the motor
leaving a hazardous situation at the pump motor.
The motor has windings, that if allowed,will carry
back voltage ,in this case,110 volts to the switch.
Both phases that make up the 220 volts required
need to be disconnected.
