I?m looking for a Code or other regulatory body definition of ?indoor? versus ?outdoor?.

Additionally, would you define a covered walk way with side panels separated 6? to 8? from the floor (concrete slab) and ceiling and open at both ends (snow and rain could accumulate on the entire length of the walk-way, high wind could blow rain in the top opening, summer sun with no breeze could result in 120?+ F temperatures) ?indoor? or ?outdoor??

Thanks for your help!

Re: Code definition of indoor and outdoor

Just when you think you have heard it all. . . . That?s a very interesting question, David. I can say that the NEC definitions do not include those two terms. I would treat the area as ?outdoor,? because any electrical components within the area would be exposed to wind and rain and snow, as you have said. But if I had to prove that that was the one and only one correct answer, I don?t think I could do it. Good luck!

p.s. Perhaps someone with more knowledge of UL requirements might be able to offer a better answer.

Thanks Charlie!

I?ve looked through the 1996 BOCA National Building Code this afternoon and find no specific definitions for either indoor or outdoor in it either. :D maybe there is something in it.

Thanks again!

Jim,

In a hard rain with a STRONG wind, yes. (lighting only, no receptacles) It is in a costal area. (within 50 miles of ocean front) and in a large open area. (no other structures, buildings or vegetation to shield it) and is used 24/7 by pedestrian traffic.

Re: Code definition of indoor and outdoor

For what they are worth, from NEMA 250 (Electrical Enclosures):
?
Indoor Locations: Areas which are protected from exposure to the weather.
?
Outdoor Locations: Areas which are exposed to the weather.
?

By virtue of reference to NEMA 250 these would also be the UL definitions.
Edit: I guess I should say,"By virtue of reference to NEMA enclosures in UL standards...

Re: Code definition of indoor and outdoor

Wouldn't it be more important to decide if it is a wet, damp or dry location?

If we are talking about what type of outlets, lighting fixtures or wiring methods to use, wet, damp or dry is the deciding factor. :)

If the receptacles have to be GFCI protected or not, then indoor or outdoor needs to be decided.

Tough call on that one, good luck. :p
 
Re: Code definition of indoor and outdoor

Bob that` the ticket I would say and heating is a key A/C not required in a dwelling but the damp/dry location would take it to the outside IMHO.We have what we call Florida rooms but if they are rooms then spacing takes the point.If just an outdoor addition then gfci rules apply.Ask your AHJ he makes the final desicion in the end!!!
 
Re: Code definition of indoor and outdoor

Ok which one fits the bill

Location, Damp. Locations protected from weather and not subject to saturation with water or other liquids but subject to moderate degrees of moisture. Examples of such locations include partially protected locations under canopies, marquees, roofed open porches, and like locations, and interior locations subject to moderate degrees of moisture, such as some basements, some barns, and some cold-storage warehouses.

Location, Dry. A location not normally subject to dampness or wetness. A location classified as dry may be temporarily subject to dampness or wetness, as in the case of a building under construction.

Location, Wet. Installations under ground or in concrete slabs or masonry in direct contact with the earth; in locations subject to saturation with water or other liquids, such as vehicle washing areas; and in unprotected locations exposed to weather.

Re: Code definition of indoor and outdoor

The residential building code mentions 'conditioned' and 'unconditioned' space. Then goes on in the definitions to define them. Still it is not a clear defined answer to your question. I think Bob's answer is at this point the best angle as to how to attack a situation like this.

Re: Code definition of indoor and outdoor

I think you have to error on the side of safety, even if this produces contridictory terms.

For example, I would call it a damp or wet location for installing outlets or fixtures. So weatherproof covers and damp location fixtures would be required.


On the other hand, I would call it indoors when considering some life safety codes. If it catches on fire, people have to be able to get out. So as an example, certain exit requirements would have to be met.

Re: Code definition of indoor and outdoor

This conversation reminds me of the GFCI when it became a requirement. Everyone knows what a bathroom is but when it was required in bathrooms, nobody knew anymore. The next cycle, the definition of a bathroom was added to the Code.

Do you know the definition of sand? It is in 314.29 Exception. Do you really want the definition of indoors and outdoors written by a bunch of Code guys? LOL :D
 
Re: Code definition of indoor and outdoor

Thanks for all of the great input. I knew the forum would not let me down. :D

I guess we will be reviewing things with our AHJ and defining the space as damp. Now to find lighting that can survive the -20? to 120? annual temperature changes. :eek:
