This answer is taken from the CEC. Table 17 states minimum size of grounding conductors. For a service conductor drawing 400 amps a #3 copper grounding conductor is needed. Also see rules 10-206, 10-700 and 10-812 if you have access to the code book.

What is the largest size ground wire that can be used for a panel?
Use #10 copper.
What size ground wire should I use for a 50 amp hot tub panel?
# 10 bare copper.
What size ground wire needed for a 200amp service panel in new jersey?
#6 bare copper wire.
Can you wire a external and an internal ground together on a drier?
The ground wire should go from the dryer directly back to the distribution panel. An external ground wire is not required. The ground wire that is in the cord set that is connected to the frame of the dryer and the ground wire that is in the feeders coming from the distribution panel, that is connected to the ground terminal in the dryer receptacle, is all that is required to satisfy the code requirement.
What size wire should be used from main panel to 50 watt subpanel?
#6 wire is needed. If placing the subpanel in a garage at a good distance, it is recommended to also install a seperate ground rod .

Use #10 copper.
What size ground wire should I use for a 50 amp hot tub panel?
# 10 bare copper.
Ground wire size for 200?
The size of the ground wire for a circuit is typically based on the size of the circuit breaker protecting that circuit. For a 200 amp circuit breaker, the recommended ground wire size is 4/0 AWG (American Wire Gauge) copper wire. This wire size helps ensure that the ground wire can safely carry any fault currents that may occur in the electrical system.
What size ground wire needed for a 200amp service panel in new jersey?
#6 bare copper wire.
How do you know what wire is ground on 200 amp service?
In a 200 amp service panel, the ground wire is typically a bare copper wire or green insulated wire. It is connected to the ground bar within the panel. Make sure to consult the manufacturer's instructions or a licensed electrician for guidance specific to your installation.
What size of ground wire for a bank of 3 one 100 amp panels?
#8 would be fine if you ground each panel separately to the ground rod
How do you select earthing conductor size of any motor panel etc?
The ground wire size is determined from the current carrying capacity of the motor feeders.
In a typical electrical panel installation the main ground wire is connected directly from a ground rod driven into the ground to the?
The ground wire should come from the ground rod and to the main electrical panel grounding terminal.
Typical home electrical panel installation the main ground wire is connected directly from a ground rod driven into the ground to the?
Ground bus in the panel.
What size ground wire is needed for a 100 amp service panel?
For a 100 amp service panel, typically a #8 copper wire or a #6 aluminum wire is recommended for grounding purposes. It's important to follow local electrical codes and regulations when selecting the correct size of the ground wire. It's always a good idea to consult with a licensed electrician for specific guidance based on your individual circumstances.
What size grounding wire do you use as the 4th wire running in your conduit from your 200 amp meter box to your 200amp service panel this is the ground wire from box to box?
For a 200 amp service, you would typically use a 4/0 AWG copper wire for the grounding wire running between the meter box and the service panel. This size is suitable for carrying the necessary current and providing proper grounding protection for the electrical system.
