I am installing a 1 1/2 hp monarch pump to draw lake water for sprinklers and other uses. What type of wire should I bury? I will be running 120 feet from house to pump.

What does the label on the pump tell you?

Is it 120v or 240v?
What is the amperage of the motor?
Are you going to use conduit?
How are you going to control the motor?

The way you ask this question is WAY too vague.

To add to Stan's questions:

5. When you say from house to pump, are you planning to pull power from the panel?
