What does 2014 code section 200.7e cover?

Inspector listed it as switches
Not sure what he means

200.7 covers identification of the neutral/ grounded conductor

There is a dearth of details here, but I'm going to take a stab at it- the inspector got somebody for not properly id'g a switch leg/loop?
 
this is residential new home.
Romex wiring

Must be the 3 way switch legs

He also listed 110.3b Smokes near fans

Does he mean smoke detectors from ceiling fans?

Whats the clearance required?

So for the Sw's he really meant 200.7 (C)1:

"Circuits of 50 volts or more. The use of insulation tape that is white or gray or that has three continuous white or gray stripes for other than a grounded conductor for circuits of 50 volts or more shall be permitted as only as in (1) and (2)":

(1) "If part of a cable assembly that has the insulation permanently re identified to indicate its use as an ungrounded conductor by marking tape, painting or other effective means at its termination and at each location where the conductor is visible and accessible. Identification shall encircle the insulation and shall be a color other than white, gray or green. If used for single pole, 3 way or 4 way switch loops, the re-identified conductor with white or gray insulation or three continuous white or gray stripes shall be used only for the supply for the switch, but not as return conductor from the switch to the outlet."

As for the smokes, he likely means that the installation violated the listing of the smokes by not following the instructions from manufacturer- need to have 3 feet from smokes to CF blade tip:

110.3 (B) "Listed or labeled equipment shall be installed and used in accordance with any instructions include in the listing or labeling"

And when you move them, make sure they arent then within 3' of an air return, or (I think) 10' of a shower, and... read the manual. It will have all the specs in it.

In addition to the manufacturer's installation instructions....

NFPA 72, sec 11.8.3.5 (5) Smoke alarms shall not be installed within a 36 in. horizontal path from a door to a bathroom containing a shower or tub.
(6) ......shall not be installed within a 36 in. horizontal path from the supply registers of a forced air heating or cooling system and shall be
installed outside of the direct airflow from those registers.
(7) ......shall not be installed within a 36 in. horizontal path from the tip of the blade of a ceiling-suspended (paddle) fan.

If your jurisdiction has not adopted NFPA 72, then, nevermind :D

good distinction. A lot of people here get the supply and returns mixed up...maybe it's just me. If you think about the air going to the air handler/HVAC instead of to the rooms, you'll see why.

OP, stay away from any big vent looking things on the ceilings. :D

(mfg directions trump NFPA, so if the SA directions say "do no install within 36" of supply and/or return vents", or something similar, you have to abide by that).

here's that 10' rule I gleamed on showers:

Note that these Kidde instructions say 3', but they also do no specify return or supply for HVAC, just "forced air ducts"

Not trying to be funny here, but the HO may want to delete the ceiling fan or put shorter blades on it if possible rather than patch drywall from moving the SA box. But it sounds like it's on your end...if so, you'll have to eat it.

The rules on SA placement are in building codes. Note that a resi fire alarm system does not fall under article 760.

Thank guys. The bedrooms are small maybe 10 x 10

Does putting SA on the wall add any distance?

Not really and afaik they cannot be wall mounted (if they can be, they'd have to be right at the ceiling anyway, so you wouldnt gain any distance). Also beware the "dead space" in corners, which is against the directions in the Kidde link.

This room is a shade smaller than 10x10 (8x9) and has a 36" fan nearly center. About 8" off the door, or on the adjoining wall's ceiling are the only 2 places where there is more than 36" from the fan tips and not in a dead space.

eta: they can be wall mounted:

http://homeappliance.manualsonline.com/manuals/mfg/kidde/0910.html?p=3

that page also has the "dead space" I was referring to

second edit: it also says "use inside wall" so I'm thinking exterior wall mount is out too
