What size service entrance conductors for a 400 amp 3 phase service?
The size of wire for service entrance conductors for a 400 amp 3 phase service could be 500 MCM copper. This is very large size wire and difficult to bend and shape, to connect to terminals in the main disconnect and distribution panel. This problem is solved by using parallel conductors or on higher ampacities triple conductors. Using parallel conductors the wire size would be three ought (3/0) copper.
Can a 200A 240V house panel be fed by number 2 conductors from a service entrance meter panel with 200A main breaker?
Absolutely not. #2awg conductors are only good for about 100 amps depending on Cu or al. see nec table 310-16.
How would you extend underground wire to your panel currently aluminum wire run to panel about 300ft I need to extend this to a new shop with a 100 amp panel 50 extra feet?
This is not a job for an amateur, but I will help you with some primary considerations. My answers are based on the United States' NEC (code) and do not take into consideration any local requirements. You do not want to extend your existing service conductors. You want to install a 100amp breaker into your existing panel and run conductors from there to your new panel. If this is a residential application you can run this with #4 copper conductors. If this is a commercial application you must run #3 copper conductors. I would answer this question based on what your shop is intended to do. If you are running professional equipment and are more or less "in business", use the commercial requirements. If you know how to properly ground a new service, and if your new panel has a main breaker, you can do what you need with 3 conductors. This will allow you to put neutral and ground conductors on the ground bar like you would in your primary panel. If you do not know how to properly ground a new service or doing so is not practical, you will need 4 conductors and your grounds and neutrals will have to be ISOLATED from each other in the new panel. Your neutral bar in this case would be insulated from the panel. In this case your new panel would become a sub-panel of the primary panel. Some panels do not have a main breaker and this is a critical consideration if you intend to wire it as a new service. Personally, I wouldn't install a panel without a main breaker whether or not it is a service or sub-panel.
What should an electrical panel rating be?
Depends on the load. Most residential homes require at the very least a 200 amp service panel.
What size neutral wire is needed for a 200 amp service panel?
The neutral is the same size as the feeder conductors for a 200 amp service.
What is maximum amps for residential exterior light?
The maximum amps for residential exterior light have different steps. One is having the service equipment like the main panel, entrance conductors, and meter base also having guidelines and code summary.
What gauge wire do you need for 220v 100a power?
A 100 amp residential panel requires that you use AWG # 3 service entrance wire.

What is the minimum service size for a 225amp residential service?
A 200 amp service panel with a 60 amp sub-panel.
Can a 200A 240V house panel be fed by number 2 conductors from a service entrance meter panel with 200A main breaker?
Absolutely not. #2awg conductors are only good for about 100 amps depending on Cu or al. see nec table 310-16.
What is the cable between the service panel and electric meter called?
Whether you have an overhead or underground feed, that section of the installation is referred to as Service Entrance Conductors. On an overhead installation, it includes the conductors on BOTH sides of the meter, from the service drop conductors (attached at the service head) to the service equipment LINE terminals. On an underground installation, it refers only to the conductors between the meter's LOAD side and the service equipment LINE terminals. The conductors on the LINE side of the meter come from a distribution transformer and are unbroken between the transformer and your meter.
What are service panel bus bars?
Typically copper conductors that provide a phase of electricity.
Can you add 100amp sub panel if your main panel is 100 amps?
Yes. The interconnecting conductors have to have the same rating as the main distribution conductors. If the sub panel is detached from the main home, the sub panel has to be treated as a new service. This means that the service has to have its own ground rods or plates and the neutral has to be bonded to the enclosure of the sub panel.

Can the load wires in an electrical service panel exit from the same end as the service cable and meet code?
Per the 2011 National Electric Code, Art 230 Services:230.7 states:"Conductors other than service conductors shall not be installed in the same raceway or service cable."Exception #1: Grounding conductors and bonding jumpers.Exception #2: Load management control conductors having overcurrent protection.
