National Electrical Installation Standards

Standards as High as Your Own

Friday, January 6, 2017


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



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.

    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
