exterior motion detectors

[mortimer]

is there an exterior motion detector that does not require a grounded electrode (neutral)?

I don't know what you think you mean by "grounded electrode"? There are grounding electrodes, and grounded conductors, but I have never heard of a grounded electrode before.

Just an FYI, we are touchy here about terms. I think you mean grounded conductor IE a neutral in most systems.
I not sure if any are made that are powered trough the load as I think you are asking. I'm sure someone here will chime in.

Only possible if you can find one made of only plastic.
But I’m assuming you meant equipment grounding conductor.

My take on the OP was that he is referring to devices that use the load for power (such as some dimmers, etc) as opposed to needing a neutral for power.

 

[LarryFine]

He obviously means neutral.

I would say they don't exist.

I don't know how a motion detector would work without a neutral unless it was rated for 208 or 240 volts.

Yes, I meant conductor:weeping:
So...one would need a 3 wire to the md?

Is this controlling a remote light? If the feed is at the light then yes you would need a 3-wire cable between the light and the motion detector. Otherwise you could bring a 2-wire feed to the motion detector and then a 2-wire to the light.

In the same way older 120V solid state dimmers worked. They shunted a small amount of current to the ground.

Or backfed through the load. As you probably know, using the ground is no longer allowed as part of the design.

Yes I remember that for dimmers and timers but I have never seen a 120 volt motion sensor that didn't have a white conductor for connection to the neutral.
