can this unit can be install outside the house? I live in Marin County California
Asked by: Hernandez
No. This unit does not have a weather proof (water tight) enclosure. You could put it in a water tight cabinet if you really want it outside.

How far can this unit be installed from the electric source (breaker box)? Basically how long of a run of the 8 gauge wire be used to the unit?

Asked by: BarryB
You can run 8 gauge wire for about 65 to 70 feet before you start to see a voltage drop. I will recommend running 6 gauge wire if you run more than 70 feet. If any questions, please contact our technical support at 877-474-6473. Thank you.
