How do you determine ground wire size?
The size of the grounding electrode conductor is based upon the size of the largest ungrounded service-entrance conductors or ungrounded derived conductors (such as for a separately derived system) or the total equivalent area for parallel conductors (AWG/kcmil).
What type of wire is used for grounding?
Bare copper is the most commonly used type of copper wire and is often referred to with the general term “grounding wire.” It does not have any sort of protective coating, however, the lack of insulation allows bare copper to have the best conductive properties.

Do I need 400 amp?
If there is no chance of adding large power-hungry equipment, don’t go to the expense of 400 amps. If you are planning on adding a swimming pool, a larger well pump, an electric pottery kiln or building a private amusement park in your backyard, 400 A is a good idea. Three-phase might be a good idea for that last one.

How many amps does a fridge use?
Amperage for most household refrigerators, is anywhere from 3 to 5 if the voltage is 120. A 15 to 20 amp dedicated circuit is required because the in-rush amperage is much higher. The average amperage is lower because the compressor isn’t running all the time, this is often measured in kilowatt hours KWH.
How many amps does a TV use?
The average American TV is 50 inches and uses 0.95 amps at 120 volts. That works out to an average TV power consumption of 113 watts. In a given year, the average TV will use 142 kWh and cost a little over 17 dollars (assuming 5 hours of use per day).
