So have individual circuits for each room in the house so each room has its own breaker as well. My main objective is to be able to use the TP-Link AV1200 powerline internet extender from the basement to the 2nd floor. Most of the breakers are 10A. I wanted to combine 2 light load circuits (Basement wall outlet which is never used and guest room wall outlets) into one circuit so they have the same powerline. Can this be done? since these circuits are basically never used, i figured combining them wouldn't do much in terms of total load.
