Many times, the various parts of the electrical distribution of carnivals are composed and mended from random parts and pieces and inevitably show the consequences of life on the road.
Starting with Part III of Article 220, which is titled Feeder and Service Load Calculation, we will finally start with the actual math work.
Let's look at the location for the grounding termination of the many electronic systems that currently occupy our households, and how the requirements have evolved and how the industry has grown to meet the challenges.
Since Article 215 is simply titled "Feeders,” let’s start by answering the question "What is a feeder?”
Part II of Article 210 deals with Branch-Circuit Ratings, starting with conductor sizing. These are some pretty basic rules so we will just cover the highlights here.
In this article we will continue where we left off discussing branch circuit requirements, picking up with 210.8, Ground Fault Circuit-Interrupter Protection for Personnel.
Article 210 covers branch circuits, which is that portion of the wiring which connects the final overcurrent device to the utilization equipment.
