Assuming that the question is being asked about "dirt"; in the United States, the volume of dirt is calculated in cubic yards. In the rest of the world, the volume of dirt is calculated in cubic meters.
A cubic yard of dirt is the volume of dirt that fits in a space 1 yard (36 inches) by 1 yard by 1 yard.
A cubic meter is 1M X 1M X 1M.
Yes, there are ground wire gauges. The approiate size ground wire must be matched to the size service you are installing. For instance a 200 amp serivce must be grounded with a # 4 bare copper ground wire.
# 10 bare copper.
Use #10 copper.
A 100 amp residential service requires a size #8 copper wire, it should be insulated in green.
#6 bare copper wire.
To calculate the wire size, a system voltage is needed.
A #14 wire will do fine for grounding a 20 amp device. That is the size of the ground wire in a 2 conductor # 12 wire building cable.
Yes, there are ground wire gauges. The approiate size ground wire must be matched to the size service you are installing. For instance a 200 amp serivce must be grounded with a # 4 bare copper ground wire.
The ground wire in a two or three conductor #12 cable is a #14 bare ground wire.
A 200 amp service panel will require a # 4 bare copper ground wire.
Yes, as long as it is the same size wire or larger as the hot and neutral wires.
Having a smaller gauge ground wire may lead to increased electrical resistance and potential overheating. It is important to ensure that the gauge of the ground wire is appropriately sized to handle the electrical load and prevent safety hazards such as electrical fires. It is recommended to consult with a qualified electrician to determine the correct gauge for your specific electrical system.
