∙ 12y agoThe 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.

∙ 14y agoFor a single phase 600 amp service, you would typically use 350 kcmil conductors. However, the specific size can depend on factors like voltage drop calculations, distance from the utility transformer, and ambient temperature. It's always recommended to consult with a qualified electrician or electrical engineer for a precise determination.

No, load wires in an electrical service panel should not exit from the same end as the service cable according to electrical codes. Load wires should enter the panel from the sides or bottom to prevent potential contact with live service conductors and ensure proper installation and safety.
To extend the underground wire to your new shop, you would need to run a new wire from the existing panel to the new shop location. Ensure you use the appropriate wire size for the distance and amperage load (100 amps) to meet building codes and safety standards. It is recommended to hire a licensed electrician to perform this work to ensure it is done correctly and safely.
A service lateral conductor is a wire or cable that connects a building's electrical service panel to the electrical utility's distribution network. It carries electricity from the utility's distribution lines into the building to power electrical appliances and devices.
The term SN refers to a panel or disconnect switch that has solid neutral bar installed. It is a small bar that allows the service conductors to be bonded to the enclosure at that point.
No, number 2 conductors are not sufficient to carry 200A. You would need larger gauge wires to safely handle that amount of current. It is important to match the wire size to the amperage rating of the panel to prevent overheating and potential hazards.

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.
If the single line is compared to another single line and the voltage that you need is correct then you are looking as a singly phase supply. The electrical classification of single phase is that any two legs of a three phase supply can be called single phase. Look on the nameplate of the distribution panel. There it will state what the panel is, either single phase or three phase. Look at where the distribution enters the building from the utility supply. If there are three insulated conductors (red, black and blue) wrapped around a bare aluminium messenger wire it is a three phase wye connection service. If you see two black insulated conductors wrapped around a bare aluminium messenger it is a single phase service.

Best way is to use a clamp on amp meter. You need to be able to put the clamp over a single conductor. This is usually easy to do in the electric panel, but for a device you need to split the conductors. You can take an extension cord you don't need and separate the conductors so you can get the clamp on a single conductor.
The term SN refers to a panel or disconnect switch that has solid neutral bar installed. It is a small bar that allows the service conductors to be bonded to the enclosure at that point.

In the service distribution panel there are termination points at the top of the panel. Two of the utilities "hot" conductors terminate on the main breaker. The neutral utility termination point is on a terminal block usually off to the side near the main hot terminations. It is in this neutral termination block where the system ground connects from the ground rods to the distribution panel. For a 100 amp panel the wire size will be a #6 bare copper conductor.
No, grounding conductors should not be paralleled per NEC standards. Paralleling grounded conductors can lead to circulating currents, potential overcurrent situations, and code violations. It is important to always follow the regulations and guidelines set forth by the National Electrical Code to ensure safety and compliance.
