Need New circuit.
 
:rolleyes: Hi folks,
tonyh here-my question is, I have a line coming from the main panel over my attic where a wall heater use to be. I disconnected the heater and the breaker is now off., but the line is still in the attic. I want to install a bathroom fan and run power to the garage from that line-which by the way is a 20a circuit. Iam pretty electrically encline, but a little help won't hurt.
How may I go about this. oh, I want to install a new switch in the bathroom for the exhaust fan - next to the switch that is already there using the new line., also there is nothing connected to this new line. One more thing, should I run the no. 12ga romex thru conduit goin to the garage?
thank you very much for any help in this matter.

First of all, can't you just use the existing power at the switch and run the new line directly to the garage?

What do you plan on using the circuit for in the garage? Is that additional power in the garage or will that be your only power? If I was running a power line to the garage or something similiar I would use 12 or bigger depending what my plan on usage was and predicting knowing me that it might increase so I can add something more in the future if I wanted without having to run new wire.

Second...Is the garage detached from the house? Described briefly your house plan.

Iam glad someone answered. I was beginign to think noone cared.
*answer to question 1, yes I can, but I was thinking of installing a GFI at the end of the incoming line from the panel, and then run a line from the GFI to the garage, and the exhaust fan for the bathroom.
*answer to question 2, this will be an additonal power-since the existing power from the panel is already maxed out on extentions.
*answer to question3, no -the garage is attached to the house.
In additon-this house has only two wires coming from the pole, and all the breakers are 20A with no.12 wire running thru the house. there is no ground wire in the switches , or recepticles.
I hope this will clear some of what you are asking. The extention to the garage is for general use only-no heavy tools of any kind.
thank you very much for answering me.

If I was you I would just install a junction box at the end of that line instead of a G.F.C.I. If you are going to install a switch anyway you might as well use the power in the box of the already existing switch. It will be a pain in the a$$ to reset the G.F.C.I. if the circuit blows because it's in the attic. If you just install the G.F.C.I. in the garage at the end of its run then you'll have it first hand where you're using it. If there is no ground wire in any of your recepticles then The G.F.C.I. won't work because it needs the ground wire. So, you'll have to run a ground somehow. Do you have metal boxes with BX(wire wrapped in metal conduit)? If you do then you can just install a wire screwed into the switch box. Because the box and BX wire is the ground. If not then you'll have to run a ground.

Here in Jersey if the panel is maxed out on space for breakers we would just install a thinner style breaker which 2 of these will take the place of one of the thicker breakers usually used. Creates more space.


With the size wire you have at least you know it's rated right for the 20 amp breakers you have.

Thanks Hammertime,
I think I'll just install a junction box like you said. You are right about the gfi., and to answer about the BX cable-No I do not have bx anywhere in the home and no metal boxes.
You have answered my request. I thank you very much.
Talk to you next time.
