What size ground wire is needed for 20 amp?
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.
What is the minimum ground wire size for a 20 amp 110 volt circuit?
The ground wire in a two or three conductor #12 cable is a #14 bare ground wire.
Ground wire size for 200?
A 200 amp service panel will require a # 4 bare copper ground wire.
What size wire is needed for carrying 100 amps under ground?
To calculate the wire size, a system voltage is needed.
Can a insulated ground wire be used in lieu of a tinned bare ground wire?
Yes, as long as it is the same size wire or larger as the hot and neutral wires.
What size ground wire for 600 amp service?
Ground is sized based on the size of the feeder wire and not the amps of the service! However, for a 600 amp service 1500MCM copper wire is one option (NEC 310.16) ;therefor, ground wire is 3/O copper (NEC 250.66) or another option is a two sets of 350 MCM copper wire then a #2 copper (since the biggest feeder wire is 350MCM).
Is 350mcm size wire the smallest wire that can be installed in a parallel permitted by the nec?
In the CEC only 1/0 and larger conductors can be run in parallel.
What size ground wire is required for 80 amp service?
Ground is sized based on the size of the feeder wire and not the amps of the service! However, for a 600 amp service 1500MCM copper wire is one option (NEC 310.16) ;therefor, ground wire is 3/O copper (NEC 250.66) or another option is a two sets of 350 MCM copper wire then a #2 copper (since the biggest feeder wire is 350MCM).
What is the cable size required for a 400 amp and 350 amp load?
350mcm
What size ground wire is needed for 20 amp?
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.
Are there negative wire gauges?
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.
What is the minimum ground wire size for a 20 amp 110 volt circuit?
The ground wire in a two or three conductor #12 cable is a #14 bare ground wire.

To calculate the wire size, a system voltage is needed.
Can a insulated ground wire be used in lieu of a tinned bare ground wire?
Yes, as long as it is the same size wire or larger as the hot and neutral wires.
Can you have a smaller gauge ground?
Yes, NEC has an entire chart on grounding.
What size ground wire should I use for a 50 amp hot tub panel?
# 10 bare copper.
