Question: Tesla Power Wall

[Erich Bloodaxe BSN]

2. I haven't done anything with electricty in forever, but...

I do have a fuse panel still, and most of my fuses are 15 or 20 amp. And I've blown a few over the years, suggesting that running several large items on a circuit runs to more than 15 or 20 amps. And I think the oven gets a 40 amp circuit.

Here's a little blurb I stole from some website

Electricity is measured in terms of amperage, voltage, and wattage. Amperage (amps for short) is a measure of the AMOUNT of electricity used. Voltage (volts) measures the pressure, or FORCE, of electricity. The amps multiplied by the volts gives you the wattage (watts), a measure of the WORK that electricity does per second.

Think of it this way: Electricity flowing through a wire is like water flowing through a garden hose. The amount of water that can fit through the hose depends on the diameter of the hose (amps). The pressure of the water depends on how far open the faucet is (volts). The amount of work that can be done (watts) depends on both the amount and the pressure of the water (volts x amps = watts).
