minimum circuits ...

ok guys, I know there's someone out there that can, off the top of there head, tell me what would be the "MINIMUM" circuits "REQUIRED" by Code in that 1600 sq ft house mentioned earlier ...
yo George ... I know you can ... m

My guess ...

1600 x 3va = 4800 va

4800va/120v = 40 a

2 20 amp circuits or
3 15 amp circuits

Do I win??
 
He isn't asking about the SA circuits, I believe, just the branches for general lighting/recepts. Then you would be adding ...

2 SA's
1 laundry
1 bath *not included in load calc*
range
Dryer if one
fixed appliances
heat/AC
might be some I may have missed
 
yo Celtic .. saved your link to look at later, no time now .. thanks .. but yes i was looking for complete circuits required .. I know its late out there, only 8:13 here .. working 7-12's rite now so will be in bed soon .. 4am comes quick ..

so I think I should get the prize !

If the link doesn't work, this is what the post from 05/06 said.

How about an example of the minimum required for a whole house. To make the example as simple as possible, let's add one single local requirement that excludes 14 gauge 15 amp circuits. That leaves us with everything on 20a circuits.

One circuit for the furnace 422.12 calculated according to 220.14(A).
One circuit for the laundry 210.11(C)(2) & 210.52(F) calculated according to 220.14(I).
This base house has no accent lighting, so we have nothing for 220.14(D) or (F).

The only things left are fixed hardwired general illumination outlets 210.70(A) in each room calculated according to 220.12 and 220.14(J)(3).
And the receptacles of 220.14(J)(1)&(2).
One circuit for general-use bathroom receptacles 210.11(C)(3) & 210.52(D).
Two circuits for general-use small appliance receptacles 210.11(C)(1) & 210.52(B)&(C).
One circuit to pick up everything else, all of the hardwired lights 210.70(A), all of the general-use general purpose receptacles 210.52(A)&(H), and the rest of the general purpose receptacles 210.52(E)&(G).

So our total is:
One for the furnace.
One for the laundry.
One for bathroom plugs.
Two for small appliance.
One for everything else.
So this is a total of Six circuits.

Furnace is one outlet.
Laundry is one plug (gas dryer).
Bathroom is a couple of plugs.
Small appliance is installed to the minimum required by 210.52(A)(1), (A)(2)(1), & (C)(1).
Everything else circuit is installed to the minimum required by 210.52(A)(1), (A)(2)(1), (E), (G), & 210.70(A).

Is this code compliant ?

It depends on the size of the house.

You have four circuits of bathroom plugs, small appliance, & everything else that fall under 220.14(J) and therefore under Table220.12. The load of 3va per sq? covers 800 sq? for these 20a circuits. So these four circuits are good for 800 x 4 = 3200 square foot home.

If the house was 3201 square feet then you would have to add one more everything else circuit for a total of Seven circuits.

If the house was 4001 square feet then you would have to add two more everything else circuits for a total of Eight circuits.

If you fill up the house with 10 times the number of small appliance & general purpose receptacles as is required by 210.52(A)(1), (A)(2)(1), & (C)(1), nothing changes in this example.

If I were paying attention, perhaps. ;)

If I got this question on a test, I would assume they were asking for the SABC's, Laundry, Bathroom, and the 3VA per square foot number and stop there and see if they had an answer to match. With no dryer, range, etc mentioned, there's no way to know if they're gas or not. IMO.

David, would a boiler require a dedicated circuit?
 
No No No! You use Table 210.24 for the number of recpts allowed. I think it was something like 14 on a 15A branch circuit.


JUST KIDDING! I think it was really more around 27,384. Or was that just in N. Carolina? Gosh I missed this subject.
 
Guess what I just found? :D

In the ROP for the 2008 NEC, someone proposed (2-102) that the number of bathrooms served by a bath GFI circuit should be limited to two bathrooms. It was rejected. In an affirming comment, a CMP-2 member wrote:
BROWN, L.: If there is a problem in the field with the overcurrent device tripping due to the simultaneous use of the bathroom receptacles, especially with the larger homes, the home builders would address the situation as they want their customers to be happy with their new home. In addition, this is no different than all of the bedroom receptacles being used at the same time. There is no limit as to the number of receptacles on a residential general lighting branch circuit.

Heh heh heh... ;)
 
Well, it's not a death-nail to the opposition; a CMP member's opinion is just like ours, an opinion. But it should be compelling, coming from a CMP member of the Article in dispute.

In the middle, the words must stand on their own. IMO, they do.

In the end, it all depends on the interpretation of the AHJ. If this process were a volleyball game, the NFPA can only set the ball, it all comes down to how the AHJ spikes it. :D
