The code was changed in 2011, our area is currently under the jurisdiction of 2008. As the code reads, it specifically does not say the panel enclosure has to contain over-current devices or switches at time of use, just that enclosures for over-current devices and switches shall not be used as raceways. I understood it that he want to leave the original panel in place and use it to splice off to the newly relocated panel. I’m not the best at explaining things, so maybe I have created some confusion as relating to the original post. The panel enclosure is not “expressly” for holding wires, cables, or busbars…it is designed (in this case) for holding switches and overcurrent protective devices. Incorrect Statements…The Cabinet is just that…a Cabinet and is subject to to the requirements in Art 312. But, the panel board can’t be used for anything outside of it’s UL testing or listing. The change you are speaking of came in the 2011 NEC, that isn’t adopted yet in my area. It’s not an issue of space specifically, it’s an issue of UL approved listing…the panel boards were never tested for or approved for use as a raceway. And, as you hopefully know, it is a violation of the NEC to use any electrical equipment for anything other than it’s approved UL listing. You will also see that raceways are specifically mentioned in the article you posted.Ĭurently, no panel board manufacturer has a UL listing for the minimum required space to provide for raceway splicing. If you will check later editions for the NEC you will see that the wording has changed and “for this purpose” has been removed. It is very hard to fill a gutter space even close to maximum fill. You need to read the entire sentence before coming to a conclusion. Sorry Robert S there is space provided and splices and feed through are allowed. The conductors shall not fill the wiring space at any cross section to more than 40 percent of the cross-sectional area of the space, and the conductors, splices, and taps shall not fill the wiring space at any cross section to more than 75 percent of the cross-sectional area of that space. Enclosures for switches or overcurrent devices **shall not be used as **junction boxes, auxiliary gutters, or raceways for conductors feeding through or tapping off to other switches or overcurrent devices, unless adequate space **for this purpose **is provided.That would classify it as a “raceway”, and panels are neither UL listed or have sufficient space for this.ģ12.8 Enclosures for Switches or Overcurrent Devices. You can not splice conductors at the interior of panel boards that contain over-current protection or switches unless the conductor terminates at the interior of the panel. My question is if its allowed to splice the feeders, or do you need to run a new feeder line from the new location of distribution panel to meter? You often find distribution panels than need to be relocated, in the bathrooms, not enough clearance, etc.
