Question:

Good Morning Charlie,

I’m working in a building that has an Emergency Distribution Panel. A 4” Conduit on the load side contains 2 feeders, one for the elevator & one for an air conditioner. A question has come up as to whether the elevator feeder needs to be installed in a dedicated conduit, totally independent of any other feeder.

Jim Metzler

Answer:

Hey Jim thanks for your question. Different systems for elevators including power circuits are generally allowed in the same raceway as stated in 620.36. The NEC does not require that elevators be supplied from emergency systems but allows that as stated in 620.91. The Informational Note to the definition of Emergency Stems in 700.2 indicates that elevators may be supplied from emergency systems.

That can be required by other codes such as NFPA 101 - the Life Safety Code, building codes or other rules under certain conditions. If the elevator feeder is supplied from an emergency system it must be kept separate from non-emergency wiring as stated in 700.10(B). What seems strange in your example is that air conditioners are not usually considered emergency loads.

    Ik vond eerst uit over de nieuwe replica rolex toen Chris Vail, maker van Lew en Huey, een boodschap vraagt ​​bijdrage van de verschillende modellen die hij zal bouwen (meer daarover hier). Kijkend door de foto's, is het allesbehalve moeilijk om te zien dat deze horloges ronduit werden gewekt door de grote replica horloges en Tudor mariniers van het verleden. Dat maakt een wonder - eisen stellen we nog een lof aan deze illustratieve configuratie? Gezien het feit dat Vail heeft de neiging om dingen intrigerend in wat hij produceert te maken, ben ik ongetwijfeld klaar om de beste over hem aannemen nu in de process.

    Despite the fact that bronze seemed to be one of the rolex replica favorite subjects on social media in 2016, the rise of the "modern bronze age" of watches dates back much earlier to 2011 when Panerai acknowledged a small, but growing demand in the micro community for rugged divers cased in bronze. Their answer? One thousand pieces of the green-dialed PAM 382, which disappeared fast, and remains one of the Italian breitling replica watchmaker’s most memorable (and collectible) special editions. Panerai appears to be looking to replicate that success with the newly announced Panerai Luminor Submersible 1950 3 Days Automatic Bronzo PAM 671, or "Blue Bronzo" – a beautiful and worthy successor to the watch that put bronze into the luxury omega replica spotlight and ultimately helped make patina great again. In case you haven't been keeping score, SIHH 2017 has been the year of the Submersible for Panerai, where we’ve seen no fewer than six new special editions, each utilizing dramatically different case materials – from titanium and platinum-infused rose gold, to the introduction of BMG-TECH on this PAM 692. It’s a fitting backdrop to grant a shot at Bronzo redemption to anyone who missed out six years ago, and opportune timing for Panerai swiss replica watches, as the bronze diver flood is still showing no apparent sign of abating.

    But if we want to find the monsters in other areas we can “long tap” on the area that we want. The cursor will be moved to the area and the application will start the search. Additionally, disappear time feature is also available on this app. Pokemesh apk
