When I measure across "p" and "n" (which I think are hot and neutral respectively) I get .717 volts. Less than 1 v. When I measure from either p or n to earth (here called PE) I get 120v. Is this correct?

Humm

If true that would seem to make PE the hot conductor. That doesn't make any sense.

Before you go any further check the power on the end of the IEC power cord only. Use the Link below for the Female IEC connector L, hot, N, neutral, E, for earth ground.

Here is what you should have at the mains 120V wall receptacle outlet.

From the hot contact (shorter of the two slots) to the neutral contact (bigger of the two slots or "T" slot) you should measure 120V nominal.

From the Hot contact to the "U" shaped equipment ground contact you should also measure 120V nominal.

From the neutral contact to the "U" shaped equipment ground contact you should measure around zero volts. Though this can vary somewhat depending on the connected load on the branch circuit wiring due to VD, voltage drop.

When I said check for continuity I was talking about through the device. From the power in, input end, to the power out, output end.

After your last post I discovered the device is not just a fused IEC male connector but actually houses a power switch, fuse, and filter.

I also learned the device is 15 amp @ 120V.

Click on the link below. Does the picture of the IEC power in male plug end of your device look the one in the picture?

If yes notice the L, E, and N?
L = HOT
E = earth ground, safety equipment ground.
N = neutral

With your meter set to continuity or ohms touch one test lead probe to the power in "E" male prong, (the end the power cord will connect) and the other test lead probe to the PE terminal on the other end of the device. The PE terminal should be the one that is at a right angle to P1 and N1. The one in the center between P1 and N1. You should read straight through continuity/OL/short.


Power switch on device must be closed, ON position.
Next touch a test lead probe to the power in "N" prong on the IEC plug. Touch the other test lead probe to the N1 terminal on the other end of the device. You should read continuity/OL/short.

Power switch on device must be closed, On position.
Next touch a test lead probe to the power in "L" prong on the IEC plug. Touch the other test lead probe to the P1 terminal on the other end of the device. With the switch closed, on position, you should read continuity/OL/short. Open the switch, turn off the switch, you break continuity. This is the HOT Line.

Post back your results.
