Better to put too many outlets then not enough. Nothing worse then not enough outlets and then needing extension cords. Which is probably why the code states 12' minimum so that you don't need one for a permanent setup.

New Addition - Thinking through electrical


I was looking for a code answer. If you look back Yoyizit's answer was based on some sq ft calculation, not code. He made no reference to distances or walls or doors. It was more of a "this is how I do it, so this is how it has to be done" response, rather than a "this is the code" response. I truly appreciate the help I receive here on the forum, but I think if you'll review the exchange you'll see Yoyizit was more intent on making a point than sharing information.

I really do appreciate the code reference, but would also appreciate some help understanding it.

For example, suppose you have a 5 ft wall and the wall has a 3 ft door in it, does the wall count as a 5 ft wall or a 2 ft wall?

Do closets, pantries, foyers follow the same code? For example, would a 4x4 closet really have 4 outlets?

How do you handle wall to wall and floor to ceiling built-ins? I see many in new homes, but how does code address these?

Again, many thanks. Apologies for this thread taking the detour that it did.

Along a wall, regardless of doors & windows there must be an outlet every 12'. Then an outlet is also required within 6' of a door (may be more to it then this)

I have a walk in closet ~9x12, there is an outlet on every wall
Someone else could convert it to a study or some other use

I'm not sure on smaller closets & built-ins
Possible outlets are required along the baseboard?
Maybe someone who knows more about smaller spaces can give you some input

My bathroom is small, there are only 2 outlets on either side of the sink. Nothing on the very short outside wall (toilet is there too). Then the tub is in an alcove, nothing on the short wall after that. The 4th wall is essentially the door to the bathroom.

Found this so far:
Might be a city reg & not NEC?

Quote:

Every habitable room 120 square feet or less in area, of a dwelling or
dwelling unit of a multiple dwelling shall contain at least two (2) separate and remote duplex outlets

Dave- Thanks so much. I wonder what the definition of habitable room is and how that applies here.

The example you gave of your bathroom is a good one, I just feel like most of the bathrooms I see (including new construction), don't have 1 outlet per wall. Think for example of a powder room.

All three of these spaces will be set up pretty similarly. Again, they are approximately 5x10. There is a door (or a window in one instance) on BOTH of the 5 ft walls and then 15"-20" deep cabinets running the full length of on of the 10 ft walls on all levels. I am not sure how to classify the space, a closet, a hallway, a pantry, an entryway/foyer, but these are the only real functions of the spaces based on located, size and shape. Does the distinction matter? Are they considered habitable space? Are there special rules for closets and the like?

Thanks!

Yoyizit- I'm not on you, sorry if that's how it seems. I was just explaining to folks that I was looking for a code minimum, not best practice and that I was committed to following codes. Sorry if I have offended.

Does anyone have any thoughts on this site? http://www.ezdiyelectricity.com/?p=95

They seem to suggest that doorways do not count as wall space. How does this apply to cabinetry?

Thanks!

Here's how we lay out plugs in a new construction.
Starting at the door to the room:
Locate the first receptacle within 6 feet of the door.
Locate the next receptacle within 12 feet of the first.

If the wall is interrupted by another door (closet, entry to a bathroom) locate the second receptacle within 6 feet of the other side of the entry. Then locate additional receptacles within 12 feet.

If there is a short wall space between door/entrances of 2 feet or more, add a receptacle there. Try not to place receptacles behind the door swing unless required by the 6/12 foot rule.

If your cabinetry is a true built in you probably can get away with no receptacles on that wall. That's up to your inspector. You might consider wiring a receptacle inside the cabinets so you can plug in and hide rechargeable items.

I agree that you should consider adding more receptacles than code requires. When the walls are open is the time to project future needs. It will always cost you more in time and headaches to try to add them after the fact.

Also, in response to your question:

"Jupe Blue- Thanks for your insight here. I am aware that each bath needs a dedicated 20 amp circuit. I also understand why pros like yourself install things per the manufacturer's instructions... liability. Can you give me any insight into why each mat would require its own circuit, aside from the manufacturer's instructions? I am just looking to understand the how and why."

That's really a question for the manufacturer technical support line. They may actually have a real reason for the over sizing of the circuit. I don't have an answer to why they require it.

Excellent. I think I understand how/ where to locate them now. Locating an outlet in a cabinet is still sufficient for code purposes? Also, are floor mounted outlets ok?

So, how many circuits would you all suggest aand how many are required by code? Overall, there will be between 6 and 9 interior outlets, 2 exterior outlets(with one 300-600 watt transformer), 3 standard exterior light fixtures (100 watts per), and 3 flushmount lights (120 per). Not including the interior outlets, that is 1260 watts combined. I know a 20 amp circuit can handle between 2000 and 2400 watts, so even if everything was running at once I'd still have between 740 watts and 1140 remaining.

So, what does code say about this, can it all be on one circuit? What do you suggest? When planning circuits it is easy to account for appliances and lighting, but how do you handle non specific general use outlets?

Thanks!
