What size wire do I need for a 800 amp service?
Conductors – 800 Amp
The smallest conductor size for a 240 Volt – 800 amp service will range from #6 AWG for a short 20′ run to 600 MCM for an extended run of 500′ based upon a 3% voltage drop for a 1-Phase-3-Wire load circuit in PVC.
What is the largest amp service to a house?
Most homes have an electrical service of between 100 to 200 amps. Amperage is a measurement of the volume of electricity flowing through wires, and this measurement can vary between 30 amps in very old homes that have not been updated to as much as 400 amps in a very large home with extensive electric heating systems.

How many amps is 400 watts at 12 volts?
If you have a solid state inverter rated at 400 watts you can expect 85% efficiency. So to work out the amps at 12 volts you divide 300 watts by 12 volts and you get 25 amps; on top of that you have the inverter efficiency to add to that figure.
