zeb Posted April 1, 2007 Report Share Posted April 1, 2007 Ran into this yesterday. Who ever put a new GE 200 amp panel used this for a junction box. Opinions needed. Download Attachment: box.jpg 54.66 KB Quote Link to comment Share on other sites More sharing options...
hausdok Posted April 1, 2007 Report Share Posted April 1, 2007 Hi, Well, it's busy, but it doesn't look like it violates the fill limitation. Hope they've got one or two screws securing that cover in place. A little quibble with the wiring attachment, though, The NM needs to be secured within a foot of where it enters that box, so there are quite a few wires where they screwed that up. Then you've got the large number of wires under that clamp on the upper right. Because it's out in the air and can cool readily, I'm not sure whether that violates the 'no more than 4 bundled' rule.

zeb Posted April 1, 2007 Author Report Share Posted April 1, 2007 The cover didn't have any screws and that was the first thing I thought when I opened it up. Is there a rule of thumb as cubic inches to wire allowed. Quote Link to comment Share on other sites More sharing options...
Richard Moore Posted April 1, 2007 Report Share Posted April 1, 2007 Try 312.8. Yada, yada.....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...Yada, yada, yada. I doubt you are using 5% of that space. Lot of air in there. Secure the cover to keep the kiddies out. Quote Link to comment Share on other sites More sharing options...
kurt Posted April 2, 2007 Report Share Posted April 2, 2007 I was educated by a really smart electrician once when I asked the question "How many wires, space, etc.?"..... He answered, "The amount of wiring allowed is that which fits easily & comfortably", or something like that. I know that will bother the folks that memorize C&V, but there's a certain nice sense to it. Quote Link to comment Share on other sites More sharing options...
Tru View Posted April 9, 2007 Report Share Posted April 9, 2007 Wires do require a specific amount of space for dissipating heat in a junction box. #14 awg. 2 cu. in. #12 awg. 2.25 cu. in. #10 awg. 2.5 cu. in. The yoke on a switch or receptacle 2X cu. in. of the largest conducter in the box. A wire passing straight through (no splices) only counts as one. All the grounds collectively, count as one (the largest ground wire) Quote Link to comment Share on other sites More sharing options...
