In the CEC (Canadian Electrical Code) the code states that from the outside meter base to the first over current device that, the run can be no longer than 20 feet.
Service entrance wire should be AWG #3 copper.
As a service entrance wire you need AWG # 3/0 gauge copper.
A 200 amp service panel with a 60 amp sub-panel.
#6 bare copper wire.
Use AWG #1 copper service entrance wire and #4 copper ground wire.
Connect other end to the ground lug in the service entrance part of your panel.
For a 200A service, the recommended copper wire gauge for service entrance cable is typically 2/0 AWG (American Wire Gauge). This wire size is able to handle the ampacity required for a 200A service safely and efficiently. It is always recommended to consult with a licensed electrician to determine the appropriate wire size for your specific installation.
Service entrance wire should be AWG #3 copper.
The wire that runs from the electric meter to the breaker box is called the service entrance cable or service wire. It is responsible for carrying the electricity from the meter into your home's electrical system through the breaker box.
are supplied by circuits on oppsite legs of the service entrance panel . if each load draws 30amps ,what is the current flow in the neutral wire
On a 200 amp or any size service the ground wire is easily identified. Look in the distribution panel for the neutral bus bar. This is where the service neutral (white wire) is connected to the distribution panel. There you will see a bare copper wire connected to the same neutral bar. This is the ground wire that is connected to the ground rods out side of the house.
No, a 1/0 copper wire size is not sufficient for a 200 amp service panel. For a 200 amp service panel, you would typically need to use 3/0 copper wire size for the service entrance cable. It is important to consult with a qualified electrician to ensure proper sizing and safety.
It is the installation of ground rods at a service entrance distribution to bring the relative resistance to ground to be within 5 ohms of the utility's distribution network. This grounding system is then connected to the service distribution with a calculated size wire and connected to the distribution at a point within the distribution panel, where the service neutral wire joins the neutral bus bar.
As a service entrance wire you need AWG # 3/0 gauge copper.
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.
