Hey Budman,
The relay you are trying to use,should be a contactor and not a relay switch. The contactor you need has a built in coil.The relay you were wired too,had to much current.Not sure about the digital timer. I know the Intermatic would handle the job!If your power went out you would have reset it.The digtal is the whole reason for this,I know.We can get your lights on! I had a contactor and left it on the shop table. I was gonna post some pics of it for ya.. Sorry! Dawg... I did get the info you needed.
