basic wiring question

[one more cast]

I have a 200amp entrance panel outside by the meter with 4 breaker slots. I had a 2/100 breaker feeding the house main panel and a 1/20 feeding an outside ground fault receptacle. I disconnected the 1/20 breaker to make room for a second 2/100 to feed the garage.I want to connect the ground fault receptacle that was unwired from the 200amp box to the house box.My question is do I have to run 1 (hot) or 2 (hot and neutral) or all three through to the house box? The neutral and ground are already connected between the 200 and 100 amp box.

Re: basic wiring question

Gotta run both, OMC. Otherwise you could create a ground loop that might make plumbing or other parts of your house hot enough to scare heck out of you.

Re: basic wiring question

somehow,, it's hard to flow what your sayin'.. <br /><br />you un-hooked the gfi from the 4 slot main outside panel to make room..<br /><br />now you want to make it work/hot again by hooking it up to a breaker in/from the house or garage panel..<br /><br />is this correct..??<br /><br />if this is correct,, just simply run/junction/extend the the circut back to one of the 100 amp panels..<br /><br />THAT'S it..done..<br /><br />( the grounding /nuetral / 'ground loop' is already done via/by the big fat main wires..)<br /><br />unless it's 150 feet run or more,, bump up to the next size wire..

Re: basic wiring question

OK let me try to explain it better. The 110 gfi receptacle was hooked up to a 20 amp breaker in the 4 slot outside main. The only wire removed was from the 20 amp breaker. The neutral and ground wires from the gfi receptacle are still connected to the outside main. It is only 10' to the inside 100 amp panel. Will it pass code to just run the hot wire from the inside box and use the existing outside ground and neutral."( the grounding /neutral / 'ground loop' is already done via/by the big fat main wires..)"

Re: basic wiring question

No! NO! that would not pass code!!!! all conductors in a branch circuit have to originate from ONE panel only.

Re: basic wiring question

'D'is right.. an that's how things get jumbled up an confusing fast..<br /><br />since it's only 10 feet and you gotta run a/one conductor/wire anyway.. <br /><br />why go there..<br /><br />why not/just a easy to run all three from the same origin/panel..<br /><br />it's kinda hard to run one wire/conductor ,anyway..
