I intend to run an extension cable from an outdoor outlet to power four pond pumps. Currently I have a mess of different wires running across the yard from three places.
The cable runs from the outlet, would be buried 1" underground, run to a 2 ft stake, where it is attached to a power strip, that the pond pumps plug into, something like this:
Each pond pump is rated the following:
- Current: 2.30 A
- Maximum power: 276 W
- Voltage: 120 V
- Frequency: 60 Hz
- Variable Frequency
Given it will need to power four of these, running 24/7, how do I know when I purchase the cable and power strip, that they, plus my outdoor outlet, that it is capable of running these, without risk of fire, blowing breakers, etc.?
