Standards as High as Your Own

Question:

Article 680 part 4 location of emergency disconnect. All other clearances for various types of outlets are measured from the I side wall of the tub. The section on measuring 5 ft for the emergency disconnect is inconsistent. Where do I measure from? Outside wall, inside wall or high water?

Mike Stebbins

A

Answer:

Hey Mike thanks for your question. You are correct it is not clear where the measurement is taken from in 680.41 but locating it at least 5 ft from any part of the spa or hot tub would be compliant. That gives you 45 feet of tolerance to meet the definition of within sight as stated in Article 100. Consider submitting a Public Input for the 2020 NEC to provide more descriptive language.

     The common rail system prototype was developed in the late 1960s by Robert Huber of Switzerland and the technology further developed by Dr. Marco Ganser at the Swiss Federal Institute of Technology in Zurich, later of Ganser-Hydromag AG (est.1995) in Ober?geri.
    The first successful usage in a production vehicle began in Japan by the mid-1990s. Dr. Shohei Itoh and Masahiko Miyaki of the Denso Corporation, a Japanese automotive parts manufacturer, developed the <a href="http://www.commonrailparts.net">Common Rail</a> fuel system for heavy duty vehicles and turned it into practical use on their ECD-U2 common-rail system mounted on the Hino Rising Ranger truck and sold for general use in 1995.[3] Denso claims the first commercial high pressure common rail system in 1995.[4]
    Modern common rail systems, whilst working on the same principle <a href="http://www.zjsensor.com">sensor</a> are governed by an engine control unit (ECU) which opens each injector electronically rather than mechanically. This was extensively prototyped in the 1990s with collaboration between Magneti Marelli,Centro Ricerche Fiat and Elasis. After research and development by the Fiat Group, the design was acquired by the German companyRobert Bosch GmbH for completion of development and refinement for mass-production <a href="http://www.commonrailparts.net/common-rail-parts/common-rail-nozzle">Common Rail Nozzle</a> . In hindsight, the sale appeared to be a tactical error for Fiat, as the new technology proved to be highly profitable. The <a href="http://www.commonrailparts.net/common-rail-parts/common-rail-injector-valve">Common Rail Injector Valve</a> had little choice but to sell, however, as it was in a poor financial state at the time and lacked the resources to complete development on its own.[5] In 1997 they extended its use for passenger cars <a href="http://www.commonrailparts.net/common-rail-parts/common-rail-injector">Common Rail Injector</a> . The first passenger car that used the common rail system was the 1997 model Alfa Romeo 156 2.4 JTD,[6] and later on that same year Mercedes-Benz C 220 CDI.
    <a href="http://www.commonrailparts.net/common-rail-parts/common-rail-shim-gasket-kit">Common Rail Shim &amp; Gasket kit</a> have been used in marine and locomotive applications for some time. The Cooper-Bessemer GN-8 (circa 1942) is an example of a hydraulically operated common rail diesel engine, also known as a modified common rail.

    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

    I think it will be better for you to connect it from high water. It will be helpful and it will also meet the requirements stated in the article 100. I hope I am clear with my statement. Feel free to contact if you need any clarifications. photo editing companies
