Preferably our body isn't what connects that electricity to the ground. Hi there, Firstly, safety safety safety! Electricity is always trying to get back to the earth/ground, we're just caging it and controlling it to do work for us before allowing it to go home. It took some digging but I found them on-line from ZING EAR. When that gave the same results, I concluded that ONLY a two-wire controller would work. To make sure it was not a faulty photocell, I had to check with another, new one. When the three-wire photocells fail, they do so in the 'ON' position. But this means that with a three-wire control, in any configuration, electricy is able to flow through the device to the load (the LED lamps).

They appear to be designed with an internal electronic relay to allow the device to handle heavy electrical loads, whereas a two-wire photocell in series easily handles current for a couple of low amp LED lamps. I've tried all configurations, but I have to face the fact that the 3-wire photocells require a parallel circuit with a hot and a return.

It wore out recently and the only replacements available were 3-wire. I installed a two-wire photocell controller about 20 years ago. It is impractical to try and run a return line. The posts are about 140 feet from each other and the wall switch is remote from both. So that post light is in series with the other, like old fashinoned Christmas tree lights used to be.

No ground, no return just two white wires to one where I wanted to install a photocell controller.
