I just changed my lights out doors on my tennis court. There are 3 wires coming out. 1 red 1 black 1 green. There are 2 20amp brakers together in the panel box. The lights have 2 black 2 white 1 thin ground. I put 70 watt bubs in. Why does it blow lights as soon as I hit switch? Please help

Sounds like a wiring error... if you're not sure that you connected them correctly, why not call an electrician?

With the wiring you described you have 240 VAC. The lights appear to have a neutral which would indicate a 120. What did you do with the white wire? Test the voltage.
Your previous post indicated 2 whites and 2 blacks, a 120 bulb. Please do not post 2 questions for the same situation.
