wiring info 14/2

hidden 1

Hi
I have a light circuit 15 amp 14gauge(7 cfl lights) ,and am going to link off of it 15ft to garage(is the only wiring close).will be putting 3 plugs,1st -GFI; and 2 cfl lights on the line.I dont plan to use any appliances /compressors,etc. Will have garage door opener1/3 hp ,and may use vaccuum ,or 13 amp saw once in a while,but not often
Do you see any problems with the set up ?

Will i be able to run the 13amp 60 hz (4500rpm no load ) saw,ok ,or small vac,even if lights are all on? I wont use the plugs together at same time even though there are only 3 on entire circuit.
Any info is appreciated.

How far is panel from the garage, 13A is alot to put on a #14 without worrying about voltage drop.

Could you not just run a new circuit out to the garage and have that on its own circuit, preferbly a 20A circuit.

Agreed - it would be much better if you can run one (or even two, while you are pulling wire) 20a circuits to the garage.

Its about 200 or 300 ft at least to box.Will i be blowing the fuse everytime i use a jigsaw ,vac,etc-alone? All are lights at 60 cfls and there will be just 3 outlets on circuit.

At 300' you will have a voltage drop of ~24 volts
At 200' it will be ~16v

Are the CFL's installed & in use ?
A lot of times they will not light with that great of a drop
Of course with only say 60w of power w/CFLs' the voltage drop is only 1.2-2v
So the CFL's should work OK

I decided to go a little further and link into the outside "Gfi breaker protected" 20 amp-12/2 as my main feed for the outlets ,and just leave lights on the 15 -as i was going to run anyway.

What is the max outlets on the 20 amp ?
That circuit has 3 outlets already to bathrooms/outside plug.
I dont believe i would need a plug style gfi on any of the line since protected in breaker ,but wondered if it is ever done..
Any info is appreciated

There isn't a max number of outlets
Max load is 20a, 2400 watts

However you can't take a feed off of a bathroom circuit
That is a code violation

spark plug

What a lot of people (who are not DIYers or PROs) don't realize is that you could, with the same effort install 2 lines (MWBC) instead of one.!

I've been re-doing my house and I am running two 12/2's into the garage, just as an affirmation of what the other posters have said. I'm a newbie at electrical work also.

I used a different nondedicated line ,20 amp-not many outlets ,not gfi linked ...-yet.
I will run 3 outlets off it transferring 1 of them..5 on all ,Gfi 1st, will be ok for what i will be using it for.
Thanks for the info

If you want (2) circuits out there you can pull an additional red wire
These 2 circuits become a MWBC - multi-wire branch circuit
Red & black as hots, green ground, white neutral
The hot feed must be on opposite bus on the panel
Easiest way is to use a 240v breaker to feed the hots

For a detached structure you can have:
(1) circuit
(2) circuits using a MWBC

OR
Sub panel & many circuits

I will just go with the 20 amp for all of it -lights also-since it has almost nothing on it anyway and i wont be pulling a lot off it.20 works for me!
Ive run it already too!
Thanks for info.
