I'm upgrading 2 outlets in a house built in 1950 (no ground wire); the junction box is in the attic, and currently the line runs from it down into a light switch outlet, and there's a downstream line running sideways and then down from the light switch over to a receptacle outlet.
Quick (ugly) mockup; the black lines show how it's currently connected; the green show what I'm considering doing:
The new line down to the light switch will be no problem(ish. You know how it goes, lol.), but rather than fight with running a new line sideways over to the receptacles again, as it is currently setup, I'm considering just disconnecting the current line and running a direct line from the receptacle outlet up to the attic and into the junction box.
My question: is this a better idea? (Receptacle will be used for electronics (PC, tv, etc.)). Are there any advantages to a direct line rather than just running a downstream line?
Disclaimer: I'm not an electrician, just a DIY'er, so I may have some of the verbiage wrong (i.e. "receptacles", "outlet", etc.)
