Did a job in a town I have not worked in for over ten years recently. Didn't know if they changed a few things. Besides having a dog house rule, and no restrictions on length of service conductors inside the building - they do have a requirement to have a disconnect of the main accessible from outside. (In the Municiple code. :roll: ) Anyway found that out after the fact...... :mad: (Someone was supossed to go find out if they had any other silly codes when they picked up the permit - that didn't happen.)

So, what I have is a meter (only) - in its tight little existing dog house enclosure. (a job I can do in a city two blocks away...) So I call the Inspector (Multi) and tell him what happened.... "No - you need a way to shut of the breaker from outside..." - So I ask, "Would a shunt trip breaker and a switch outside work for you?" - He answers, "Whats a shunt trip?" :roll: (neither he or the AHJ, or 3 other inspectors have a clue what one is...) Never got an answer on what thier intent was for having this code in the first place - as the dog house, and allowing SEC's under the finish kind of contradict the requirement.....

BR2125ST = $125 - re-doing a whole service and relocating the grounding - priceless.......

Anyway, I get to do this service again tomorrow - and lesson learned - ALWAYS CHECK LOCAL CODES! BEFORE YOU DO THE WORK!
 
Something's not adding up. If they want a disco outdoors, then you don't really have any service entrance conductor inside, do you?

By the way, what's a "dog house" as it relates to service equipment? Some sort of standardized shelter for the equipment? Got any pics of such?

"Dog House" = an enclosure to 'shield the service equipment form veiw from the street.' Which in this town does not include the service conductors.... :roll: And the "dog house" can be inside the building, and you can run from the POC over-head INSIDE THE WALLS from the weather head the total hieght of the building INSIDE to get to the service equipment INSIDE AS WELL. You can even run from the back to the front of the house with SEC's - INSIDE. So long as you can open a little door, and reach INSIDE to shut off the main.....

You may ask how the fire dept shuts of the service? With a hot stick.... I saw one - I asked....

Doesn't add up? Thats right! The whole town is littered with services that are total abominations.

Ill get you some pic's manyana....

True - but when factory installed, and not removable from said breaker (riveted together with the breaker with internal mechanism and handle tie)..... Even though listed as an "accessory", not available from CH alone. Good point though.....

Maybe, but add -1021 to many manufacturer's plug on breakers, and it's a "permanent" feature, so you might as well call it a breaker type.
 
Oh... I see. You can bring your riser or lateral in totally indoors, but you still have to stub out to an outdoor disco someplace. Geeze. Trade one hazard for one convenience. Do they at least make you run your indoor service conductors in RMC until they hit an overcurrent device?

That's a poco rule - RMC for all SEC's.... But these people even go as far as to mandate that the POC for the drop be below the weather head - where the POCO only "recommends" and never enforces it. But you can have the riser visable - but not the "equipment" say a meter or disconnect, so what many people have is a rotting plywood abomination "shielding the equiment from view from the street." But have full unobstructed view of said rotting mess around the panel. Or you can be nice and put a little hatch to read the meter, or reach into the building to shut it off.....

Oh - and even if it is in a little shed and/or inside - it needs to be nema 3.....

Just tell them it's a remote-control-trip breaker.
