• Branch and Feeder Circuits HowStuffWorks

    There are two types of circuits: feeder and branch. Feeder circuits use thicker cables that travel from the main entrance panel to smaller distribution panels called subpanels, or load centers. These auxiliary panels are located in remote parts of a house or in outbuildings, and they are used for redistribution of power, such as in a garage.

  • Branch Electrical Circuits Explained

    Your home's electrical system begins with main serv wires that enter your home from an overhead utility line or underground feeder wires and connect to the main serv panel, usually located in a utility space. Up to this point, the system hardware belongs to a power utility company. But from the main serv panel, the current is divided into individual branch circuits, each of which is

    Electrical circuit load capacity is the total amount of power that your home actually will use. In order to decide how big of an electrical serv is needed in your home, one has to do a little math home. Older homes often only had a 60-amp electrical serv, connected to a fuse panel.

  • Do branch circuits sharing conduit with sub-panel feeder

    Presuming both panels are connected by non-flexible metal conduit, that is allowed to serve as the ground, so you don't need any ground wires at all. In this case, the metal conduit is allowable for the ground for the feeder, and also allowed for the ground for the branch circuits. So you're all set.

    20/12/2011· I agree with all replies so far, and now we know the definition of feeder and branch circuit based on NEC. But as far as estimating world is concerned; any size wires that would fit in conduits up to 1" with respect to 40% max fill considers to be a branch circuit. 1 1/4" and up is feeder. Let's say we know you could pull 2 #12 in that 1 1/4" pipe.

    Article 220 of the National Electrical Code (NEC) provides requirements for calculating branch-circuit, serv and feeder loads. Definitions for the three types of loads that Article 220 covers are in Article 100. A branch circuit is the circuit conductor between the final overcurrent dev protecting the circuit and the outlet(s). Branch circuits are divided into four categories: appliance

  • Feeder Conductors vs Branch-Circuit Conductors EC&M

    Article 215 covers the installation, conductor sizing, and overcurrent protection requirements for feeder conductors. The requirements for feeders have some similarities to those for branch circuits. But in some ways, feeders bear a resemblance to serv conductors. It’s important to understand the distinct differences between these three types of circuits.
