I'm wanting to install a new 120V service to my pond to run a fountain, lights, recepticles, etc.
Here are the facts. Any opinions on what I should install would be appreciated.

The line will come off our house 200A Breaker Panel.
The pond is approx. 600' away.
The fountain runs 7.5 Amps.
Continuous service
Copper cable.
Looks like I should use a #6 or even #4 AWG. To stay within voltage drop.
What is recommended for underground cable Mfg. And where to buy.
What concerns do I need to concern for the Breaker Panel?
I'm thinking of a 15 Amp breaker.

Any help would be appreciated. I do electrical work but it is all control wiring for machinery so my supply side experience is limited.

Thanks, Thackery

Using a voltage drop calculator arrives at a #4 copper wire for a 2.3% Vd:

1 conductors per phase utilizing a #4 Copper conductor will limit the voltage drop to 2.30% or less when supplying 8.0 amps for 600 feet on a 120 volt system.

This allows 8 amps for the pump alone.

Copper is expensive, and I doubt a direct buried cable is available. You can use wire THHN/THWN insulation and PVC conduit.

Readily available is #2 aluminum 4 wire URD cable, that can be direct buried. Conduit would be recommended if the soil is rocky or provide an easy method of replacing later, or add more protection of the cable.

Thanks for the answer TKRussel, I have found several sources for the #2 URD-AL cable. Looks like about $1000 for a 1000' roll + shipping.
I figured I would buy the 1000' roll and have the remainder for other buried cable projects I have coming up.

I need advice on breaker panel capacity. Basically I don't know how to calculate how many breakers/amps I can use in my 200 amp service box. Where would I find the calculation rules for a panel?
I'm searching this site for information.

Thanks, Thackery
