the trend here, not sure if it's code ... but smoke detectors on a well used circuit, so it cannot be inadvertently tripped without knowing or intentionally tripped to silence nuisance alarms

If the breaker gets tripped, the damned things start chirping to let you know the power is out. It's the same annoying chirp that tells you a battery is dead/dying.

^^ I have and it pissed me off trying to figure out which one(s) it was. I replaced every one of them in my own home because of it. My favorite chirp is when they are disconnected and the batteries are removed and they still do it. I replaced about 10 of them in a house, the customer had replaced the batteries recently so I took all of them out and gave them back. Driving down the road, at least one, maybe more were chirping in the back of my van, but didn't start until after I got on the interstate. I pulled off at an exit that seemed like an eternity away to throw the whole bag of them in a gas station dumpster.

For all I know, we might have been on the 84 code when I did it. Maybe there was an amendment letting it happen?
I started shacking houses around 92 not long after I got out of the Army.
From around 70-82 I did mostly commercial and service work.
I do remember going into some apts in bellevue in the early 90s that were built in 60s-70s I'm guessing that always had panels in living room coat closets,always had to wait for people to move their junk out of way to get at the panels.
I always considered them to be fire traps myself anyway,they could be smoking a long time before anybody noticed.

I put closet doors maybe a foot in front of my main panel, sun panel, and transfer switch. I have had the electrical inspector in there at least twice with no comments about the closet doors. It is most definitely not a clothes closet.

Never quite understood the accessibility rule. My breaker panel is outside the house a good couple hundred feet away...

It's a 200' walk for you to reset a tripped breaker?

Some locations to a breaker would defiantly entail more than 200'.

I'm not familiar with the code for this... but is their 200' number a "as the crow flies" sort of deal?

There are a lot of houses where a 200' walk could be involved with getting to the panel. In the grand scheme of things, 200' isn't very far. With the comment about accessibility included, you make is sound as if you are going outside and walking to the neighbors house. I'm not going to measure, but I would bet it's more than a 200' walk to get to my panel from the master bedroom. The panel is in the basement, under the master. Out of the bedroom, across the house, down the hallway to the stairs, down the stairs, through another hallway and back to the other side of the house.

Accessible just means you can get to it without tearing anything up.

Article 100.

Accessible (as applied to equipment).
Capable of being reached for operation, renewal, and inspection.

Accessible (as applied to wiring methods). Capable of being removed or exposed without damaging the building structure or finish or not permanently closed in by the structure or finish of the building.

Accessible, Readily (Readily Accessible). Capable of being reached quickly for operation, renewal, or inspections without requiring those to whom ready access is requisite to take actions such as to use tools (other than keys), to climb over or under, to remove obstacles, or to resort to portable ladders, and so forth.

Yeah I guess the fact that I have to go outside and walk 75' is where I get upset.

If there was an electrical emergency inside the house I can run around naked, barefoot, etc. to the panel and not have to worry about running into pitch black nighttime hoping I don't stepping on sharp rocks, rattlesnakes, cholla, prickly pear, and then finding the key or breaking the lock off on the exterior panel to switch a breaker off.

I don't understand the reasoning behind outdoor panels. Never have, never will. Your first post says outside a couple hundred feet away. It sounds like it's a couple hundred feet away from the house.

Fundamentally if I'm in one section of the house yeah... I'm walking probably over 200-300' to get to the panel.

Just terrible design IMO. Not to mention the # of breakers that just start failing from being chock-full of dust in nuts.

One is that I put a subpanel in a large closet and he told me it can't be in a closet.
Anyone know the code violation on that? Lots of homes I've seen have sub-panels in a closet. We've got a sub-panel in the laundry room.

Also, failed me because apparently we need to have three wired smoke detectors in the addition all joined together so if one goes off, all go off.
Yea, that's a thing.

Sounds like you didn't do badly... Moving a sub-panel seems like the main PITA though.

I just googled it. It appears that 1981 was the first year that mentioned clothes closets. There was either an amendment excepting it or the inspector didn't know about it when I did two of them in 1997.

Take a few minutes and adjust your attitude. You are responsible to know and follow the code if you are going to do this work.

Do not get mad at the inspector for doing his job and noticing your errors. Remember he is the inspector not the instructor.

Be aware many locations when you do major work like a new panel the smoke alarm system must be brought up to the current code even in rooms that required no other work get a new alarm. An alarm in every bedroom and another just outside the bedroom. You are likely to need a dozen in most homes.

Well... I will mention it... In addition to wired smoke detectors... they require at least ONE carbon monoxide detector "Combo" as well. One smoke detector in EACH bedroom, one near the kitchen and the Carbon Monoxide detector combo on the ceiling in a main hallway. Usually at the top of the stairs if you have stairs... if not... somewhere in the central hallway.

Good point on the carbon, but the only locations that should be required should be likited to the addition. I don't know what the addition consists of, but if they want three, I'd guess it's two bedrooms and a hallway. If so, the carbon would go in the hall.

Just to throw this into the mix.... We recently did a reroof and the inspector made me replace two of the smokes with combo smoke/CO units. One in the hallway on each floor. It was required to pass the final on the roof.

Welp, as soon as he passes us on the final, that bad boy is getting flipped back to the closet again. If not, it'll be in my son's (4) room and the only thing it powers is his room and his sisters (7) room. They are the greatest friends and most bitter of enemies. He'd pop that door and start hitting switches anytime she wronged him.

For those that don't want to look it up:

240.24(D) Not in Vicinity of Easily Ignitible Material. Overcurrent devices shall not be located in the vicinity of easily ignitible material, such as in clothes closets.

Good thing there is no easily ignitable material in garages!

The question is if you can address the "vicinity" issue, IE per Table 110.26A 1 and 30" width of working space, would that be "passable"?

I spent two hours unhooking the panel and flipping it Friday night. Then ran the smoke detectors like he wanted. Have him scheduled to come out again sometime this week.

Does your code require wired detectors ? here it does not, it does require interconnected however. I went with 3 Nest's, 2 in house, 1 in detached garage and they all talk to each other, that was good enough for my inspector. My Wi-Fi is on battery backup, so Wi-Fi will be one of the last things to go in a bad situation, meaning they should work even in power outages for a day or so.

I have Nest Protects as well, and was curious - it doesn't actually need WiFi to communicate with each other. From https://support.google.com/googlene...py=,how-nest-protects-connect-with-each-other

Nest Protects connect wirelessly using a Nest-developed protocol called Weave that lets Nest Protects communicate with one another safely and securely without an active Wi-Fi connection.

Weave uses 802.15.4 and Wi-Fi 802.11 b/g/n to create reliable, flexible, secure and low-power communication between Protects.

You can think of the 802.11b/g/n protocol as the connection that communicates with the outside world and performs tasks like automatically updating Nest Protect software or allowing you to get mobile notifications on your phone. You can think of the 802.15.4 protocol as the low-power connection that lets Nest Protects communicate with each other.

This means your Protects can continue to talk to one another, and can let you know when smoke or carbon monoxide is detected in other parts of the home, even if your Wi-Fi network goes down.

For the smoke alarms go by local code(s) of course....

Here they are on their own breaker with only a commonly used, usually hall, light. The purpose of the one light is that it is used often and if the breaker was off or tripped the home owner will notice right away. They were also exempt from being on AFCI or GFCI to reduce any potential for nuisance trips. Like others noted, 14/3 and the red wire is for signalling. I do 14/2 from the panel and then 14/3 after the first alarm to all of them.

Building code here requires minimum one on each floor and outside of every bedroom. I ended up with eight at home which is more than needed by code.
