House Electrical Guru`s...a question or two, ok three

[SuperFudge]

Thanks Alot for the input guys !


I think i understand how Questions 1 and 3 work now.

Ok, i think im getting this...

It turns out both #2 and #3 questions cables have 4 wires total, red,black,white and a bare ground for the former, and red, black,white and green for the latter.

So i am understanding these are identical except for the green wire instead of bare and i have a total of four circuits.

Heres what i would like to do with Question #2`s cable,

I am kinda gun-shy with this one, as it continues on into a wall and is lost to sight.... and im about 90% sure it is only feeding two standard 110 recepticles.

I Have all Baseboard heating in the house, so i was scared this one may have been 220v feeding one or two...But, i cant find anything that stops working when this breaker is tripped except for the 2 plugs.

Now, I have already split the line and was planning a junction there, in this junction, i was going to just feed a line of 4 recepticles on the fishroom side.

Now If i get this correctly, It wont matter how its wired then downstream.(110 or 220)
i can still tap into one of the hots(black or red) or both (for two individual circuits) and the whites...say, using the red and white to a recepticle or two, and likewise for black and white it will give me 1 or 2- 110v lines.... And then placed back in line to go back into the wall again.

And is this a safe thing to do? (i like my house Un-charred )

Thanks again fellas,
