I need to monitor a 240v circuit to find out why a motor keep burning up. Can anyone recommend a piece of equipment to do so. It may take a few month.

Recording the current for a period of time can be very helpful in identifying non-electrical problems.

This is a 1 1/6 hp 2 speed spa motor. Controlled by a Len Gorden pneumatic timer. I've replaced timer 3 times. The motor is the 3rd one replaced by pool tech. I've taken apart the last timer to find the low speed micro switch that is rated for 2hp and 20 amp is fused together and the pump won't shut off because the micro switch can't open. Why is there not a scratching head imotacon?:?
Now we are getting somewhere. You probably don't have much of a problem that recording meter will uncover other than excessive run time. If you have serious voltage problems you will likely have trouble with more than just this motor.
I don't like seeing microswitch or equivelant switching such heavy loads. Even if they are rated for it they don't seem to handle it very well. If motor is "stuck" in running position is it designed to run continuously?
Is there anything preventing the high speed winding from being energized at same time when this switch is stuck? That would not do the motor any good if both speeds are energized at same time.
