How to Do Home Electrical Repairs: Tips and Guidelines ...

Circuits to all the devices in your home that require electrical power start from the fuses or circuit breakers. 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.

Feeders Vs Branch Circuits | Mike Holt's Forum

Nov 29, 2019· Branch circuits connect the branch overcurrent device (e.g. branch breaker) to each load. Or to a daisy-chained group of loads, as is the case with receptacle and lighting circuits. The way to tell that it is a branch circuit, is that it will not have multiple paralleled overcurrent devices on the load side of the circuit.

What is an AFCI | AFCI Safety

A device intended to be installed at the origin of a branch circuit or feeder, such as at a panelboard. The branch/feeder AFCI provides for detection of arcing faults that can occur line-to-line, line-to-neutral and line-to-ground. To be able to handle shared neutral circuits (a common application in older homes), a two-pole AFCI can be used.
