Hi all,
I have a single phase motor (115VAC 1/4hp) that keeps failing our internal leakage current test. We are measuring about 0.1mA of leakage current when the pump is plugged in, but powered off.
The only thing the the live is wired into is an IEC connector then into a two-terminal SPST switch rated for 277VAC. The neutral is not wired through the switch and the earth is connected to the motor chassis.
With the motor plugged in and powered off, I am measuring 117.5VAC on the live terminal and 0.98VAC-1.2VAC on the neutral terminal. Any ideas on what could be causing this leakage current when the pump is power off?
