Note that this table is as per the NEC Table 310.15(B)(7). In the following table, we mentioned the NEC recommended 100 Amp Wire Size for Service Entrance Conductors. Depending on the type of conductor you chose, the 100 Amp Wire Size varies. The three common types of conductors are Copper, Aluminum, and Copper-Clad Aluminum. If you have this service, then what is the 100 amp wire size you should use for your Service Entrance Conductors?īefore proceeding, you need to remember that we need two sets of Service Entrance conductors one set between the Drip Loop (roof Service Head) and the Meter Base and the other between the Meter Base and the Main Service Panel. The 100 amp service is the bare minimum nowadays. 100 Amp Wire Sizeĭepending on your contract with the utility, the Service capacity or amperage can be a minimum of 100 amps and can go all the way up to 400 amps. Regardless of the type of transformer, the underground conductors are buried 4 feet in the ground and connect to the meter base at your premises.įrom the meter, we have to use a Service Entrance conductor to connect to the Service Entrance Equipment (the main service panel or circuit breaker panel). The underground conductors can come from a pole-mounted street transformer or a concrete pad-mounted transformer. In an Underground Service, the three conductors are insulated and are known as Service Lateral, if the utility provides them, or Underground Service Conductors, if you provide them. You have to connect another set of Service Entrance conductors from the meter to the Service Entrance Equipment (the main control panel or breaker panel). You have to tie the Service Entrance conductors to the Service Drop conductors and pass them through the service head on the roof and then through a Service Mast.įrom here, the Service Entrance cable goes to the Meter Base. Here comes the Service Entrance Conductors. The service drop terminates at the service head on the roof and from here onwards, it is the responsibility of the customer to follow NEC guidelines and properly wire the cables. The utility is responsible for these cables and calls it the Service Drop. In an overhead or aerial system, the utility company brings three cables, two hot and one neutral, from the pole-mounted street transformer to the Service Head at the roof of the house. The two common methods for bringing the service cables into the house are the Overhead Conduit System and Underground System. When we say the term “service”, we mean the wires and cables responsible for bringing electricity from the street transformer to the main circuit breaker panel in your home.

If you are planning to install or set up 100 amp service panels or sub-panel wiring, then we highly recommend you consult with an experienced and licensed electrician. This is just a technical discussion on the 100 amp wire size you need for such installations.

WARNING: This is not a user guide on how to wire the 100 amp service entrance or sub-panel. If you are just starting construction on a new home or if you are planning to extend the existing electrical system with a sub-panel, then you need to know the 100 amp wire size (or wire size for appropriate service or feeder wire). After that, we will see what wire size is suitable for 100-amp service panel or sub-panel wiring. In this guide, let us discuss the importance of wire and conductor sizes in electrical systems. The next logical discussion is regarding the 100 Amp Wire and what AWG wire size should we use for the 100-amp service entrance. So, it is often rated for at least 100 amps. While the circuits from the service panel are suitable for carrying 15 Amps or 20 Amps of current, the main service entrance must carry all the load in and out of the house. So, choosing a proper wire size as per the current it can carry is essential. Wire and cables are responsible for carrying the current in the circuit. If the service panel is the heart, then the wires and cables are the arteries and veins of the system.

Using the service panel, we distribute the electricity all over the house by carefully designing the circuits. The main service panel or the circuit breaker panel is the heart of the residential electrical system.
