In article 334-2, it says Multifamily dwellings of Type III, IV, and V construction. Then it says FPN No.2: See Annex F for determination of building types.

Where is Annex F? And what is type III, IV, V??

rknikko... which edition of the NEC are you referencing? The 1999? Or an earlier edition?

In the 2002 and 2005, Article 334 is NM cable and Annex E is used to identify building types, Annex F is a cross reference to Articles in earlier editions. In the 1999 NEC Article 334 was for MC and there wasn't an Annex F.

I'm not seeing that wording you referenced in any recent NEC. But, I didn't go back any farther than the 1996 NEC. [Linked Image]

BTW. The Annexes (or is that Annexi [Linked Image] ) are found in the back of the NEC. But, in reality, I assume you knew that.

Hope this helps. [Linked Image]

FPN.#2 334.10 See Annex E for detrmination of building types [NFPA 220, Table 3-1]

Type3= (combination of combustible & noncombustible)
Type 4= Heavy timber)
type 5 = (wood Frame)

In both the 2002 and 2005 additions Annex E covers the type of construction and Annex F is a cross reference table. Look at the very back of the book just before the index.

Yoop... I just had a "duh" moment. I'm flippin' through NFPA electronic versions looking at 334-2 over and over and not actually looking for the wording rknikko quoted. Yep... there it is in 334-10.

Sometimes it helps to just open up the old paper version and let the text jump out at you! [Linked Image]

I guess the Mike Holt version must have a coupla' typos... and missing pieces and parts.

Time to buy the 2005 from the NFPA. [Linked Image]

At the risk of being called a nitpicker I would point out that the usual description of type three construction is "Ordinary Construction, Masonry bearing walls with wood floor and roof assemblies." It is also often called "brick with wood joist" by firefighters.

Building construction types are explained in the current building code adopted by the jurisdiction of question. Where NFPA 220 Table E is similar to the IBC which is adopted in many areas, I would advise that assigning building types in a specific area be in accordance with the local building code. ( if your jurisdiction has adopted the NEC there is no guarantee that the building enforcement branch has adopted table E of NFPA 220).

Type I and II structures in general do not have any wood framing members, with the degree of flammable interior determine the degrees of each type.
As mentioned Type III is generally a masonry envelope with standard 2 X, 6, 8, Construction

Type IV is Mill Construction Stone or masonry exterior with Heavy timber interior (Plank floors etc.)
Type V is a typical (for the NE anyway)wood frame dwelling.

Remeber that just because a building looks like type I or II doesn't mean it is. For example, a super WalMart is typically a type V building.
