POWER LINE COMMUNICATION SYSTEM

摘要

A power line carrier communication system is provided to orderly arrange a breaker and a coupler by making the breaker and coupler have the same width dimension, even without blocking commercial power inputted to a parent apparatus, and make the length of a power line for connecting the breaker and coupler uniformly. A power line carrier communication system comprises the followings: a magnetic(2) connected to each power line of plural systems; a parent apparatus(1) which is connected to the power line of the first system which is one of the plural systems; and a coupler(3) which is connected between the power line of the second system except the first system and the parent apparatus.
