2023 110.26 Spaces About Electrical Equipment
HTML-код
- Опубликовано: 27 сен 2024
- New rules for access to and from electrical equipment (biggest change in the entire document?), flat working space, equipment above ceilings, and dedicated space for service equipment.
Thankful for your helpful interpretations and explanations.
Hey you have to move your sprinkler pipe😂😂😂😂😂😂. We’ll be moving electrical before that happens 98% of time. This is a great post Ryan. Thanks!
Excellent👍👍
If we’re following edge distance for wedge anchors correctly this would be a solid reason to need the 6” for a pad, as 3/8” + anchors are only about 1-2” from the edge of the enclosure but require 3-6” from edge of pad. Whenever I see a switchboard enclosure flush with the pad, it’s virtually always not compliant with edge distance. Note: screw in concrete anchors and epoxy require much less but still do have an edge distance requirement.
Thanks for your support, I got lots of information by this video
I'm thankful for the new requirement for clearance all the way to the floor for equipment in the ceiling. Where I used to see this problem quite a bit was for HVAC disconnects in the ceiling of office buildings. I've literally had to stand on top of fixed filing cabinets to service some of these things. But I'm wondering how enforceable it is under certain circumstances. For example, an electrical company puts the basic rough in (including HVAC equipment in a dropped ceiling) in an office building that hasn't even been rented out yet. Then the space gets rented and furniture (including fixed cabinets) start moving in. Now.....I'm a combo inspector. Do I have to tell the new business "you can't put that cabinet under that HVAC shutoff in the ceiling"? Do I have to make them hire an electrician to move the disconnect if they want to put a fixed cabinet in that specific location?
Are you the Authority having jurisdiction?
As an licensed electrician that went through an apprenticeship it is perplexing that the ahj and or inspector doesn't have the same rigorous standards and/or hours to tell me my work is good. And has to go to RUclips to ask questions.
@@andronatroncoulomb9299 My career change to a combination inspector was just within the last 2 years. In that 2 years, I have achieved over 20 certifications from the ICC, and am on the path to becoming a Master Code Professional. Before that, I worked in the field as an electrician for over 20 years, and I still have my Master Electrician licence. But even with all that code experience, the question of "how do we enforce this" often comes up. In those instances, I am not too proud to ask for the consensus of my peers.
For GFCIs' some manufacturers in their literature state to maintain the integrity of the GFCI receptacle, the 'TEST' button should be utilized once per month.
Great job, great video
Listed fire exit/panic hardware can only be installed on outswinging doors.
Amazing video! I happened to find this while i was trying to determine the layout of a utility room in an existing dwelling. The owner wishes to install a sub panel underneath (but not DIRECTLY below) the ducts going to and from their furnace. There is 9" of space between the ducts, and the panel would be placed directly below that gap, and 1-1/2" conduit will be ran out of the top of the panel and between these ducts. Based on your video and 110.26(E), the 9" gap between the ducts and directly above the panel provides sufficient room for the dedicated electrical space for the panel, is this correct?
That sounds compliant!
@@RyanJacksonElectrical amazing! And thank you for the quick reply!
A follow-up to my previous question: I am trying to determine if the height of the ducts are too low. The ducts measure 6'3" from the floor to the bottom of the duct, which would normally conflict with the 6'6" minimum height for working spaces. However, since this is an existing dwelling and the panel amperage will not exceed 200A (will either install a 150A or 200A panel), then the installation of the panel is permitted as long as 110.26(A)(4) is followed. The part I'm not sure about is the NEED for the panel to be in that spot in the basement. 110.26(A)(4) talks about exceptions for equipment that is required by installation instructions or FUNCTION to be located in a space with limited access. In this case, the function of the panel is to reduce the number of home runs needed from one area of the home to the main panel due to the large distance. Could I make the home runs all the way back to the main panel? Sure, but then I would need to replace their main panel to have enough spaces. 110.26(A)(4)(4) says "The maximum height of the working space shall be the height necessary to install the equipment in the limited space. I would argue that 6'3" is enough space to install this panel, but I would love to hear your take on this scenario.
can i ask you something about GFCI?
Sure
Grettings, what I understand from this rule is that it requires clearance from equipment that is not part of the electrical system as a whole, meaning A/C ducts, gas pipes, etc
I had an inspector fail an installation saying that my knife disconnect was in violation of this rule because there is a communication box under it.
My problem with this assessment, is that according to chapter 8, all conventional communication systems are part of the electrical system
At the end of the day, inspectors will be inspectors, but I will like to know from more professional sources if the inspector is right or if he misjudged the situation based on the NEC
The dedicated space is dedicated to the electrical installation, which includes communications equipment.
In residences, front and back doors normally swing in. One reason is to prevent tampering with hinge pins. Commercial buildings will require out swing for ease of evacuations.
Hi Ryan What about the generator concrete pad? Cant extend more than 6 inches of the generator?
Loving it
