Baron,

Since no one else has chimed in, here is my $0.02. Check that there are three wires and the transformer should take 110v and wire a three prong plug matching colored wires and plug it in and see what happens. But don't come back here and tell me it fried. My real advice is contact a electricity literate friend or hire an electrician, that is your safest bet and worth the money. JMHO. Aloha

Yes you may plug it into the wall just buy a pig tail. The wiring is simple green goes to green and the other colors don't matter.

Hi Baron,

Yeah what Ted Said. That is what I meant to say. Aloha

Absolutely, you can. Inside the box behind the panel is another small enclosure. You will find 3 wires (black white & green) You can purchase a plug from an irrigation dist. called a pig-tail, or get a grounded extension cord from HD, and cut the plug end off and split the wires to make the connection. Use common sense!! If your not sure, go to the Dist and get the pig tail. The person should be able to show you how to do it.
