Powerline dumb question

[martin_metal_88]

You may think I am nut's or just plain stupid but I have a not that quick question that I would like if some of you could help me ( no google didn't )

I understand the fact that a powerline send a signal in the electrical system and blablabla, my question is : Does it work over both line in electrical panel ( L1 - L2 )or the circuit have to be on the same breaker line.

If it work with the live wire then it can't work on both L1 and L2's so it have to work over the neutral since most of them don't have ground no?

And, will a powerline work on fuse system?

Thx, if more details needed just ask ;)

As long as the units are connected on electrical outlets that are hard-wired into the same breaker panel, powerline ethernet will work - even if using old-style fuses.

[martin_metal_88]

so they have bo be working on the neutral then.

You will get better performance if they are on the same circuit, but as 3.0 said it should work as long as they are on the same panel. I was not sure about fuses...thanks 3.0

DISCLAIMER your working with live circuits so take caution to shock

Note: check the outlets if unpolarized will have to change them (have electrican do it) other is check if your polarized outlet is term'ed proper using a multi-meter in correct range and AC or 120vac neon test light

hot = live

No worries about electricity it's my field of study ;) My main question was if it is working using the live line, how the hell can a power outlet on L1 and another one on L2 ever communicate since L1 and L2 NEVER touch each other.

[KaptCrunch]

yes the load connects L2< -load-> L1

[martin_metal_88]

And where? On the left side you connect one of the 3 phases ( let's say phase A ) and on the right side you connect phase B or C so you can have a single phase 120/240. If they ever touch it'll make a great photo ( that's the main point into sectionning outlet when you have 3 wire circuit )
Just trying to figure out how it work.

live = AC black wire

neutral =white wire

ground = green wire is a common return path for electric current, or a direct physical connection to the Earth.

SO! sorry for this thread resurection but it's not useless.
I went back to school and asked my cable and communication teacher ( this guy specialise in that kind of thing ) how a powerline was working over 2 phases.
His answer was kinda smart and short.
Micro capacitor send a signal that is so high in frequency that it can go over the ground and neutral of the electrical system so it's able to pass from L1 to L2 and vice-versa.
He also told me that those capacitor where in the range of Pico faradf which is damn small XD

Thx to him I finally have a suitable and reasonable answer :)

Hope this will help someone some day!!
