Shop wiring

[Twogrn]

I'm adding a table saw to my "man cave" the shop/garage and I have some concerns about power requirements. The house was built 4 yrs ago and the outlets are wired with 15 amp breakers. With a beer fridge and all the lights on the same circuit I guessing the breaker will trip when the 13 amp saw gets turned on. So I beleive I need to run a second circuit, can I use flex cable with 12/2wg pre-wired that I see in HD and just add a 20 amp breaker to the box?

If there are any better ideas please speak up

Thanks, sorry that thread is so long..

Definitely a good idea to run a separate circuit for the saw.

Is this shop attached or detached?

Like Wyle asked, attached or detached ?

If you're attached, why not just use 12/2 NM (romex) instead of the bx/mc like you're asking about ? The NM would be easier to work with and probably half the cost, maybe cheaper when you include the fittings to attach it.

Unless there's some local code that requires the armored stuff for the garage ? Or is the breaker box in the garage where you're only making a short run ?

As long as you are running new wiring, I would run a separate circuit for the refrigerator too. Additionally, I imagine that as long as you are running wiring, you may as well add a few more circuits too.

I know my suggesting that running a whole bunch of wiring is probably sounding a little bit goofy, but in all fairness, you really don't want to have a lot of stuff running on the same circuit.

I would certainly recommend the lights being on their own circuit. The last thing you want is to be working at night and the breaker trips and you are in the dark. Try finding the breaker panel in the dark while tripping over stuff.

Thanks for good feed back, as for a few of the questions, yes garage is attached, and the only reason for using flex was it will need be run through pipe in basement and to meet code and the final six feet will needed to be piped or run through flex. So its only a matter the expense for the flex that will run through the garage ceiling to drop point about 30--35 feet. And yes I do like to save $$ if possible.

Why not just run AC(armored cable) all the way from panel to outlet?

All receptacles in the garage require GFCI protection. Since your adding a table saw, think about what other tools you wish to, or will add, and their power requirements, it may be prudent to add a subpanel. The garage being attached or detached will dictate how the wiring is done.

Another thought? Run some 2/0. Two legs of 110, a neutral and a ground and put a 100 amp subpanel in the garage. Then you can do whatever you need in the garage with no impact on the house.

Nominal voltage is 120v/240v

And he could impact the house if he uses too much power and trips the main breaker.

Okayyyy.... two legs of 120... He will never use too much power. My shop is set up like this and I have a enough equipment to fill a small fab shop... Oh wait! It IS a small fab shop. Have never popped a breaker in the house. Of course both legs are on 100 amp breakers in the house panel and a one or two man shop will never pull all of that at one time.
