So I'm setting up my rooms, turns out I had a free double pole 240v 20amp breaker free on my main panel. It's 10/3 wire, and I checked it before I wired everything up to make sure it was in order.
Off the line coming from breaker I installed a junction box and split the line in two also using 10/3 wire. Those lines each run into their own Tork 1104 240v mech timer. One timer splits into two 240v 20amp outlets, the other feeds just one 240v 20amp outlet.
Off the timer with two outlets I am running a digital 1000w dimmable ballast with a 1000w HPS. There is nothing yet hooked up to the other timer or other outlets. In the future I will be running 3 1000w digital ballasts total, but for now only one is hooked up.
So here is my problem, when my ballast turns on and my bulb fires up, the voltage on the other 2 outlets reads 1,500v - infinity. On each hot leg to ground, both legs together, just the ground alone with the common probe touching nothing. Also every bare metal spot on my timers reads the same. But when I check the power at the main panel it's normal. Before the bulb fires up and just the ballast is on its normal. Everything runs cool to the touch, I've touched the bare metal parts on the timer, such as the on off switch and I didn't die, that was before I took my readings btw. The ballast and bulb run fine. To try to trace back the problem I checked all my connections, and did a continuity/ohm test all the way back to the main panel on all 3 wires (both hots & ground). And I did this at each outlet, at each junction box, everywhere I could everything checks out, little to no resistance. To check continuity I switched the main off disconected the wires from the 20amp breaker and used a jumper wire to make a circuit with each line. My meter is digital and was set to the 200 ohm setting the smallest on my unit, the largest amount to f resistance I encountered was 00.9 the others were 00.6 and when I touch the leads of my meter together I get 00.6.
I have a diagram to show my wiring, I don't know how to make a wiring diagram so bare with me.
